### Compression Of Cast Iron Experiment

Wednesday, July 2nd, 2008

## Introduction

This is an 'A' Level Design & Technology project. At the time when this was done this project was worth 15% of the marks. It helped me get an A grade in 1998. The whole project is reproduced here for your reference. The only parts of the project not shown are the photographs and the graph.

 This is a real A-Level project and as such is intended for educational or research purposes only. Extracts of this project must not be included in any projects that you submit for marking. Doing this could lead to being disqualified from all the subjects that you are taking. You have been warned.

## Aims

This is an experiment to see if cast iron shears at an angle of 45° and also to check if the cast iron samples breaks at pressure at which books say it should break.

## Planning Strategy

I plan to alter the compressive apparatus first to measure the force at which the cast iron samples sheared. I will then work out what size of cast iron sample the apparatus can take before making the individual samples. If I make the samples first then I could end up with 10 samples which were unsuitable for the apparatus.

The book 'S.G. Iron Properties And Applications' puts the average pressure at which cast iron shears at 98kg/mm². The maximum load that the compressive rig will produce is 350kg/mm². The maximum area of the cast iron samples can therefore be worked out.

Maximum area of cast iron samples = Maximum Compressive load ÷ Average Pressure at which iron breaks.

350kg ÷ 98kg/mm² = 3.57mm²

The maximum diameter of the samples is then worked out.

The maximum diameter that each cast iron piece can be is 2.13mm. I shall therefore make all the samples with a diameter of 2mm.

Once I have made and tested the apparatus I will make the samples. I will make them all out of the same long piece of cast iron so that the samples would be uniform. I will make them one after another so that they can be as similar as possible. If I make a few first and some more a few weeks later then small changes in the lathe settings could cause irregularities in the samples which would lead to an unfair test.

In order to make sure that the samples are all tested in the same environmental conditions I plan to do all the compressive tests in the same one hour period if possible.

## Cast Iron

Iron is a widely used metal in industry. It is fairly soft but is often alloyed to form Steel which is very hard. Iron is made in a blast furnace by the reduction of iron ore by carbon monoxide. The carbon monoxide gas comes from the burning of coke.

Iron Oxide (Iron Ore) + Carbon Monoxide ----> Iron + Carbon Dioxide

Limestone is added to remove some of the iron's impurities and then it is ready to be cast into `pigs` so it can be used in the iron industry. This pig iron is melted again and the correct amounts of other elements are added to make it into cast iron.

Cast Iron contains the following:

• Carbon 3.0-4.0%
• Silicon 1.0-3.0%
• Manganese 0.5-1.0%
• Sulphur under 0.1%
• Phosphorus under 1.0%

It is often used to make frames, engine blocks and surface plates.

## What I will be Doing

Many identical cylinders will be compressed using a compression apparatus. The compressive force is provided by a car jack. By looking at the gauge I will be able to measure the compressive pressure at which each of the samples shears. The average of these results will be taken to find the iron's compressive strength. By looking at all the samples I will be able to see if cast iron does shear at an angle of 45° when enough compressive force is added to it.

According to the book S.G. Iron propities and applications the compressive strength of iron is 94-102kg/mm².

## Safety

When the tests are carried out the compressive rig will have a shield around it to prevent any of the iron from being propelled across the room when it breaks. As a lot of force is going to be applied to the samples they could easily explode into many fragments which could be very dangerous. I will also be wearing safety glasses to protect my eyes and ensuring that there is no one near the apparatus when the tests are being carried out.

## To make the iron cylinders

 I took a square piece of cast iron and cut it into a long rectangle with ends of 10mm by 10mm.
 I put this rectangular section into a lathe and made it into a cylinder with a diameter of 9mm.

From this I cut 10 equal length pieces each 15mm long. The top 5mm of each cylinder was cut using the lathe to have a diameter of 2mm as below. The measurements of the diameter were taken using a micrometer screw gauge.

Above you can see the dimensions of each cast iron piece. To ensure accuracy all the blocks had to be identical or as near to identical as it is possible to get.

The larger 9mm diameter base is left to give the cylinder stability when it is in the compressor. Each of the samples is put in the compressive rig and an increasing load is applied to each piece until it breaks. The diagram below shows the compressive rig.

 As the car jack is pumped up it applies a pressure to the iron. The Picture on the left shows the compressor before the pressure is applied, the picture to the right is what is looks like afterwards.

The pressure can be read off from the gauge which is connected to the car jack.

In order to measure the pressure at which the cast iron shears it was necessary to add a slave needle to the gauge which will tell us the pressure reached before the Iron snapped. In order for the needle to be put in I had to completely dismantle the gauge which is shown above and cut out a small cylinder of brass to lengthen the gauge shaft. A hole was drilled into the end of the brass cylinder so that it could be press fitted over the original shaft. The main needle was silver soldered onto the brass shaft.

 A slave needle was cut out of steel and was put onto the extended shaft so that it could move freely. A short length of brass wire was cut and silver soldered onto the slave needle 40mm from the end as shown to the left so that as the main needle moved it would push the slave needle with it. The needle was slightly curved downwards so that it would 'stick' at the point where it was pushed to by the main needle.

## Results

I carried out the above experiment and I obtained the following results.

 Test Number Pressure at which Cast Iron Sheared (Kg) Pressure at which Cast Iron Sheared (Kg/mm²) 1 310 98.68 2 320 101.86 3 315 100.27 4 300 95.5 5 315 100.27 6 295 93.9 7 300 95.5 8 310 98.68 9 300 95.5 10 305 97.08 Average 97.72

These results are to the nearest 5kg due to the scale on the gauge. The pressure needed to break the sample per mm² is worked out by.

Pressure/mm² = Pressure at which iron sheared / (Π x r²)

These results were then plotted in a scatter graph showing the pressure at which each sample broke.

## Conclusion

These results are very close to what would be expected S.G Iron Properties And Applications said that the compressive strength of iron is 94-102kg/mm² and all but one of my results are in-between the boundaries. The average is 97.72kg/mm² which lies roughly between the two values. By looking at the samples 8 out of the 10 samples showed a shear of 45°. Two of the samples had just been broken up totally and showed no angle but this was probably due to a weakness in the metal or the sample being incorrectly placed in the compressor. The 45° angle can be seen in the photograph below. The angle on the picture appears to be slightly different to 45° but this is because the sample was not quite at 90° to the camera. The angle on the sample is 45°.

The reason that iron break at an angle of 45° is due to the structure of the atoms in the material. They are arranged in a way so that if enough pressure is applied the atoms will slide past each other at 45°.

## Limitations

1. The tests were not all carried out on the same day so the temperature for the tests could have varied. A change in temperature can make the metal expand or contract and so lead to irregularities in the sizes of the samples.
2. The lathe does not cut the metal smoothly, it leaves many small grooves and scratches in the metal which can cause it to be weak in places and so alter the load at which the sample would break. This could also account for the reason that two of the sample totally broke up when put under pressure instead of splitting at a 45° angle.
3. The samples may have had sand or gas inclusions which may make them irregular and so reduce the accuracy of the tests.
4. The scale on the gauge is only to the nearest 5kg so readings more accurate than to the nearest 5kg can not be taken.

## Improvements / Extension Work

1. Instead of testing each sample individually a special rack could have been built to compress all the samples at once. However the pressure needed to compress 10 samples may have been to great to achieve. The shattered samples may also intermix unless they were somehow kept separate.
2. The compressive rig could have been improved if a small pit was drilled into it the same diameter as the base of the iron samples as this would ensure that the samples are standing straight in the rack and do not fall over. This would ensure that the anvil comes straight down on the sample each time to ensure that all the tests are consistent.
3. Different sizes of cast iron could have been used as by using samples with larger diameters it would be easier to see the 45° angle.
4. Test could be done to see if the way that that the pressure applied to the iron affects it's compressive strength. In this experiment the pressure was applied gradually but if the pressure was applied very suddenly the results could be quite different. In order to do this a weight could be dropped from a fixed height which would apply a very sudden pressure to the samples.

### Extrusion of plastic investigation

Tuesday, July 1st, 2008

## Introduction

This is a 'A' Level Design & Technology project. At the time when this was done this project was worth 15% of the marks. It helped me get an A grade in 1998. The whole project is reproduced here for your reference. In is an investigation into the method of making extruded plastic floor skirtings. The name of the company has been changed to CompanyX. The name of the product range has been changed to the Purple range. All the names of the people in the company trees have been errased.

 This is a real A-Level project and as such is intended for educational or research purposes only. Extracts of this project must not be included in any projects that you submit for marking. Doing this could lead to being disqualified from all the subjects that you are taking. You have been warned.

## Contents

I went to CompanyX Extrusions to follow the design process of their recently launched Purple range of floor skirting. I went there to examine what had happened from the original idea to the designing, producing, selling and marketing of the finished product.

## Planning Strategy

I will be going to CompanyX for one afternoon a week for 10 weeks. I plan to spend three afternoons at the extrusion site, two afternoons in the Sales office, two at the marketing department and two afternoons at the storage and packaging department.

By splitting my time up so that I spend different afternoons in the different departments I will be able to see how the company operates as a whole and so get an idea of how the various parts of CompanyX interconnect. I will prepare questions in advance so that I can find out as much information as I need on every visit. I will talk to several people on each visit, hopefully the manager in charge of the section and one of the ordinary employees in the section. This way I will be able to get information on how the area is operated by the management and also how the ordinary employees work in the section. From this I should be able to obtain a balanced view of how CompanyX operates. I will take notes whilst I am at CompanyX and write them up when I got home to ensure that the information is fresh in my memory. From these notes I will be able to prepare a report on the extrusion of the Purple range of floor skirtings.

## The Company

CompanyX makes extruded plastic parts. Most of their products are used in the building industry for stairs and for carpets. The parts are made at K---- Street and then sent to their C---- Street factory where they are packaged and distributed.

CompanyX operates on a three shift rotating pattern from Monday's to Friday. The shifts are from 6.00am - 2.00pm, 2.00pm - 10.00pm and 10.00pm to 6.00am.

CompanyX has it's own tool room, quality control laboratory, die cleaning store and a material recycling facility.

One of their newest products is the Purple range of floor skirting. It consists of a plastic skirting board with the pattern already printed onto it. This makes it easier for the architects and decorators to match the skirting to the decorations. It is also easier because normally a pattern has to be separately applied to the skirting but there is no need for this with the Purple range.

CompanyX do not stock large quantities of each of their products. If a certain product is ordered they just produce a new batch. They are able to do this as each product has a quick turnaround. The product can be quickly made then a few hours later that extruder can be making a totally different product. They have 12 extruders so they can make many different products simultaneously.

Like all of CompanyX's other products the Purple range is made using extrusion. This is where soft plastic is forced through a die to make the right shape

## The Sales Team

The sales team is responsible for collecting the orders from customers and passing them on to the manufacturing department. It provides a service from Monday to Friday. The area managers from the sales team will install their products for customers and also give advice on which product is most suitable for them.

## Marketing Department

The marketing department provides marketing for all the CompanyX products. It is responsible for producing product literature, samples, market research, corporate hospitality and exhibitions to promote it's products.

CompanyX have their own design and printing facilities for any promotional literature.

## Quality Control Department

Some of the bigger CompanyX customers have included the Ministry of Defence and the National Health Service, they have insisted on checking their suppliers such as CompanyX to make sure that the goods being supplied are of good quality. CompanyX therefore had to ensure that they had good quality control procedures in place to satisfy their customers. CompanyX Extrusions have kept their quality standards high and because of this they have obtained the BS 5750 certificate. This certificate confirms to their customers that they have good quality control procedures in place.

## The Beginning

In 1995 CompanyX noticed that a German company was importing decorative floor skirtings into the country. CompanyX decided to make their own version of it. This was to be different to all their other products as this was the first decorative skirting that they had ever tried to design. They contracted an outside company to do some research into floor skirtings. From this research they had a rough idea of the sort of product they wanted to make. It had to be attractive and functional and be easy to fix onto the wall. There was no formal design process for this product. The design team just made freehand sketches until they came up with a shape that was pleasing to the eye.

CompanyX then had to work out how to get a decorative effect onto the skirting. They got an outside company to try laminating the plastics with the patterns but this proved too costly and it only worked with hard plastics.

They found an English company which had had a lot of success with laminating plastics for small children's toys such as 'Pogs'. CompanyX consulted them and found out that they put their patterns on the toys using heat transferred plastic foils. An American company designed a variety of patterns for them and sold them the finished foils in 170m long rolls.

## The Manufacturing Process

The actual plastic used for the Purple range is PVCP. They buy it in bags of small pellets. These are only about 5mm long to ensure that they can be melted down easily. The pellets are also produced by extrusion. Soft hot plastic is forced through a die containing many circular holes by an extruder. Pellets are cut by a rotating blade which is on the end of the die. There are around 300 colours of plastic pellets available that are made in this way.

When CompanyX get an order in for an existing product they can very quickly set up all the machines ready to make that product. The most important part in the extruders is the compressive screws which push the plastic through the dies.

## Extrusion Of The Purple Range

To force the plastic through the die they use compressive screws which rotate slowly at about 30 RPM. As they rotate the plastic moves along them. These screws heat the plastic to make it soft. As the plastic moves along the screw it gets compressed due to the thread of the screws getting closer together. The diameter of the screws also decreases so by the time the plastic has reached the end it is very compressed and flows easily through the die.

Each screw is around 1.5m long and is made up of a steel core. The screws used for soft plastics are single screws which have a much shallower thread than those used for harder plastics as they do not need to apply as much force to the softer plastics. The screws for hard plastics are twin screws which have two screws next to each other which rotate in opposite directions.

Twin Screw

The compressive screw is housed in a barrel and it is an exact fit to ensure that plastic cannot work it's way back along the barrel. Four metal Micre Bands are placed around the barrel. These bands heat the compressive tube up to around 160 -170 ºC which is sufficient to make the plastic soft and workable.

Soft Plastic Screw

The screws consist of four separate zones.

At the thickest end is the Feed-Zone. This is where the plastic pellets drop onto the screws. These pellets are fed into the machine by a hopper which lets the PVCP pellets freely fall onto the screw by gravity. CompanyX also do extrusions with harder plastics, in these machines the pellets are fed onto the screws by a pump.

The hoppers on the extruders are kept continuously filled by a simple suction pump which sucks the pellets from a feeding funnel at the bottom of the machine into the hopper at the top of the machine. This makes it much easier to keep the extruders full of pellets as if they did not have these pumps in place someone would have to climb up about 2 metres of stairs to fill the hopper.

Hopper

After the Feed-Zone the thread of the screw starts to get closer together and so compresses the plastic. This is know as the Compressive Zone. In this zone the amount that the plastic is compressed depends on the type of plastic. Soft plastics such as used in the Purple range are only slightly compressed as they are soft enough to be easily extruded without the extra pressure. The harder plastics are put under a lot of pressure to get the soft enough to go through the die.

The third zone is the Decompressive Zone. This is only present in the screws that are used to extrude hard plastics. In the extrusion process of hard plastics bubbles may build up in the plastic as it is pushed along the screw. If these are not got rid of then this could ruin a whole batch of products. The Decompressive Zone is the area where the bubbles are got rid of. Here the thread of the screw gets wider and so releases the pressure that the plastic was under. The barrel in this area has many small holes in it's surface. The area around this part of the barrel is also under a vacuum which sucks all the air out of the barrel. The plastic is not sucked out as it is not molten enough to get out at this point. It is also no longer under pressure so it will not be forced out of the holes.

In soft plastics, air bubbles are simple able to leave the barrel by flowing up the screw. They therefore do not need a Decompressive zone. Instead at several points along the screw they have jagged edges known as mixers which simply mix the plastic as it passes through them. These mixers make sure that the plastic is of an even composition and make sure that any air is not trapped in the plastic.

The final area of the screw is the Metering Zone. Here the plastic is once again put under pressure as the diameter of the screw narrows to it's smallest point. The plastic is compressed heavily so that it will be able to flow out of the die easily.

## The Die

The dies are custom made by CompanyX for whichever product they are making at the time. They are around 300mm long and have a diameter of about 200mm. In order to function properly they must be at a temperature of about 140 - 150 ºC. If they were fitted cold onto the extruders then it would take about two hours to heat up to the correct temperature which is not acceptable as it is costing CompanyX around £35 per hour to keep their extruders functioning. A few hours before the dies are needed they are taken out of the die room and put in a pre heater which heats them up. When they are needed they are wheeled onto the factory floor and fitted onto the extruder. It then only takes about 25 -30 minutes for them to settle at the right temperature. This period of time is known as the settling down period. This pre heating technique allows CompanyX to get the maximum possible use out of each of their extruders.

Once the plastic has passed through the compressive screw it is soft and is at the right temperature to be extruded. However it is also spinning and so it's motion needs to be altered from spinning round to go straight onto the die. This is achieved by having a breaker plate in-between the screw and the die. This is a metal cylinder around 50mm long which has many small holes in it. When the plastic reaches the cylinder it is forced to go through the holes and so passes in a straight line towards the die.

A range of dies that CompanyX can use

The soft plastic goes through the die and is now in the correct shape. It is still molten so it has to be kept in the right shape and cooled down quickly. The plastic passes through a series of toast racks if it is a soft plastic or calibrators if it is a hard plastic. These toast racks or calibrators are exactly the same shape as the original die and so allow the plastic to keep it's shape while it is cooled down.

The hot plastic is drenched in cold water as it passes through these toast racks and the area between each toast rack is under water so the plastic can cool down as quickly as possible.

The calibrators of the hard plastics are almost identical to the toast racks of the hard plastics except that as the plastic passes through the calibrator it is pulled through a vacuum. The calibrators have many small tubes in them that suck the plastic onto them. This helps to make the surface of the plastic as smooth as possible. If there was a tiny scratch in the die then this mark could be passed onto all the plastic that passes through it but the Calibrators help to get rid of these scratches by sucking the plastic into the shape that it is meant to be.

The extruder plastic passing through the toast racks
and being sprayed with water to cool it down

As the plastic passes out of the row of toast racks it is blasted with a jet of pressurised air which blows any water droplets off it. This is very important as any water on the plastic could cause bubbles to form under the decorative foil when it is applied which would result in that batch of products being scrapped.

As the plastic is pushed out of the extruder by the screws it is also pulled off by a separately controlled Haul-Off which consists of two belts which pull the plastic between it. The two machines are separately controlled so this can create problems for the plastic. If it is pulled out much faster than it is being pushed out by the extruder then the plastic will stretch and end up being much thinner than it is supposed to be. If it is pushed out faster than the haul off is pulling it out then it could end up too thick or it could even end up buckling.

A Haul Off

This can be put to use if the size of the plastic needs adjusting slightly. If they find that the plastic coming out of the machine is too thin they simply slow down the haul off slightly and if the plastic is coming off slightly too thick then they speed up the haul off.

## Decorative Foils

As the plastic skirting passes out of the haul off is goes through the foil heat transfer machine. The plastic passes through a cloth to make sure that it is totally dry. The foil which is slightly too big is rolled onto the plastic and heat is applied to the area where it needs to stick to the skirting. The foil is applied under tension to ensure that it does not buckle or have any bubbles in it. The excess foil is pulled away by another roller leaving just the skirting with the decorative pattern on it.

Foil Transfer Machine

Once through the foil transfer machine, a protective plastic film is rolled onto the plastic. The soft plastics are then rolled into rolls by a mechanical roller. Hard plastics cannot be rolled and are therefore cut into lengths of about 2-3 metres by the haul off before being tipped into boxes.

## Cutting The Finished Product

The haul off has a counting mechanism built into it so that once a set amount of plastic has passed through, it guillotines the plastic if it is a soft plastic. The haul offs which are used with hard plastics use a saw to cut the plastic to the correct length.

Guillotine

## Fitting The Purple Range

When used in the UK the finished product is designed to be glued onto the walls by using a solvent-based glue. The product is not flat and has a gap but CompanyX recommend applying a lot of glue so that the gap is totally filled. The method of fixing the skirting to the walls is slightly different in the rest of Europe where due to EEC regulations they cannot use solvent based glues. Here a strong form of double sided sticky tape must be used.

## Quality Control

Samples are regularly taken of the products as they come off the extruders. Each product has a specification sheet which details the acceptable error limit. If any of the plastic does not conform to the standards then that batch is scrapped.

The sizes of the plastic are checked with an electronic micrometer. The samples are then taken to a testing room. Here they are cooled to freezing point and a 1kg weight is dropped on the sample from a height of 1m to test the strength of the plastic.

A hand held scanner known as a spectrometer checks the colour of the plastic to make sure it is exactly right. CompanyX buy in their plastic in the colour they want them so if something is wrong with the colour they have to go to the plastic manufactures to find out what is wrong with the colour.

CompanyX make sure that the foil stays on the plastic by using the selotape test. For this a fixed length of ordinary selotape is stuck onto the sample and the ripped off. To pass this test none of the foil should come off with the selotape.

An abrasive test is done to test the strength of the sample. An abrasive wheel is lowered onto the sample with a fixed amount of pressure and is allowed to rotate 200 times. Only a certain amount of plastic is allowed to come off in this test.

To see how the sample ages CompanyX place it in an oven at 60°C. One day in this oven ages the sample by 16 days so they were able to make sure that it could survive for a year easily in less than a month. The Purple range is designed to last five years so that after five years they hope that the companies will have to order a new batch of the product to replace the old skirting.

If a sample fails any of these tests then the whole batch is scrapped. The soft plastics can be sold back to the plastic manufacturers who melt them down and make new plastic pellets out of them but hard plastic have to be sold onto a scrap merchant for a loss.

## On Site Testing

Once the product had passed all these quality control targets it was decided to give it a real life test. In April 1996 CompanyX installed the product at F---- School in M---- and in D---- Hospital. CompanyX installed the skirting in areas such as the canteen in F---- School where they knew it would get a lot of wear. After six months they went back to these places to check the progress of the skirtings. CompanyX found that the product had worn well so they decided to launch it in November 1996.

## Marketing

The marketing department was involved from the start of the manufacture of the Purple range. They had to conduct a survey to find out if there was a need for the product and also to find out what architects might want from a wall skirting. CompanyX pay 'Focus Groups' consisting of architects, designers and distributors to have an open discussion on what they would like to see out of a product. They found that the Purple range would have a good market in modern office buildings and in private hospitals. Once they had found that there was a market for it they could start planning the marketing whilst the production team made the product.

The Purple range is different from most other products as it is "Architect Specified" which means that if an architect is designing a building he may put in that the building is to use Perspective's wall skirtings. As CompanyX are the only people to make this product it means that if they can convince the architects to add this skirting to their designs then they are guaranteed some sales.

The marketing department have the job of making the product known to the industry and the architects. They produce single A4 information sheets that are sent to approximately 5500 distributors and architects which costs them £3700. They also produced more expensive material such as brochures, sample boxes, and 'clapper board' sample cases which are given to serious potential customers. As their sample boxes cost £5 and 'clapper board' sample cases cost £10 they can't afford to give them out to everybody. They had to organise a launch day to which many customers were invited. They also got news of the range into about 20 of the trade journals for which they pay up to £90 for having a photo printed in the editorial.

It costs around £250,000 for them to research and promote a product but it is essential as people can't buy a product if they don't know about it.

## Sales

The sales department is divided into 12 areas, each dealing with a specific area of the country. Each sales person is responsible for all the distributors in his or her area only. CompanyX sell their products to 80-100 main distributors around the country. They prefer not to deal with the builders directly and if they do ring up they are referred to their nearest distributor. The diagram below shows this relationship between CompanyX and it's contractors.

Distributors buy CompanyX goods because they have the largest range of products in the floor and stair edging business. The have an 80% market share in the UK. A lot of their competitors can sell the goods more cheaply than CompanyX, but the greater range of products that CompanyX sell ensures that they should be able to keep their lead in the UK markets for the foreseeable future.

When an order is telephoned in the sales person can quickly call up the details of any of their products or customers from a database. With having the sales people only responsible for a certain area of the country the sales people can quickly get to know the customers and so are able to deal with their orders more efficiently. Once the order has been taken it is sent by an internal network to the factory where the products can either be fetched from the warehouse or a new batch can be made.

CompanyX then store the products till they can be sent to the customer. They have regular delivery of the products throughout the country ranging from every other day for the London area to only once a week for Scotland.

The sales people also are responsible for dealing with any problems or queries that the customers may have about the range of products.

## Conclusion

The Purple range of floor skirtings was launched on the 11th November 1996. I visited them up to June 1997 and only a small amount of The Purple range had been sold. They initially produced a small batch which was worth several thousand pounds but did not sell any of it. This floor skirting now has to be scrapped because the protective plastic on the product starts to deteriorate after six months.

There lack of sales is partly because they have many other products to sell and market so the Purple range gets left out in favour of CompanyX's older but more marketable products. If they do want to sell it they need to have a more effective marketing strategy to make sure that all the architects know about it. It will only be bought if the architects specify a CompanyX floor skirting in their plans so they need to send samples and information out to the architects so that they know what the product is. They have sent samples to distributors but they will not but it unless architects start wanting the Purple range in their designs.

As having a decorative floor skirting is only cosmetic to a building the architects or builders would probably prefer to use the cheaper plain floor skirting in order to cut costs. Therefore it will only be bought for buildings where there is extra money to spend on making the interior look better.

It is also only designed to last 3-4 years which is a factor which will turn a lot of people off this product. People do not want to have to change their floor skirtings every few years, they want them to last for a long time. CompanyX naturally would like companies to buy a new batch of the Purple range every 3-4 years but many of these companies are much more likely to want a harder wearing alternative that needs a lot less maintenance.

They however are not too worried by the lack of orders because with products such as this it usually takes a few years before the orders start to come in. The Purple range is a good idea for a floor skirting and in use looks much more attractive that the usual plain floor skirtings so it is certain to become quite popular in the next few years.
