Plastics Directory: a Source for Captivating Products, or Technology for Making Such Products

With its malleability (plasticity) and ability to accept different colors, plastic is a material that can convert even day-to-day utility articles into decor items. And a plastics directory is your one-stop resource for all kinds of highly saleable products (or the technology and equipment needed to make them).

A quick look at some typical plastic products reveals the huge variety possible.

The Compact Disc (CD) in your computer or video player

The jerry can you use to store different kinds of liquids

The kitchen balance you use to measure out cooking ingredients

The plastic film that shows off your products as they are

The intriguing and fascinating range of toys that your children, or you, play with

The sturdy components made with engineering plastic

Replicas that can reproduce an uncanny look of the originals, such as ivory carvings and silk clothing (rayon)

A good plastics directory is your source for products to sell (or use). Or if you prefer to produce the products, the plastics directory’s sections on plastic machineries, equipment and materials could help you locate several suppliers of these, and get competitive bids.

Plastics Directory – A Niche Directory

The discussion in the previous section illustrates how niche directories are particularly valuable for a niche audience. Persons interested in plastics products would find a plastics directory the ideal resource to locate products, equipment and ever services (like consultancy services) they are looking for.

Very often, the directories accommodate only businesses located in specific countries. For example, a UK Plastics Directory might only list suppliers in the UK. This is a way to promote the businesses in one’s own country. In fact, such niche directories are sometimes produced by regional development agencies seeking to promote the development of specific industries in their regions.

Another way such niche directories provide value to their users is through specialized categories. Whereas a general business directory might have a single category like plastics, or a few categories like plastic machinery, plastic products and plastic materials, a niche directory could have more elaborate categorization.

For example, here is one classification system adopted by a plastics directory:

Plastic Films

Plastic Flow Control Equipment

Plastic Hardware

Plastic Injections Molding Tooling & Services

Plastic Materials

Plastic Packaging Machines, Equipment & Supplies

Plastic Products

Plastic Raw Materials & Supplies

Plastic Safety Equipment

Plastic Sheeting

Resins

(Source: http://www.plastics-malaysian.com/ )

It would be evident that with the above kind of categorization, specific users could organize their searching much more purposefully.

One way for the niche directories to add even more value is through how-to articles, market news and other resources of business interest. Such a plastics directory could be a complete resource for those interested in plastics.

Conclusion

A plastics directory is a good example of a niche directory. Such niche directories could provide much greater value to a niche audience than a general business directory. For example, more specialized and elaborate classification, tailored to the particular industry, would help readers to quickly locate the precise products or services they want. Supplemented with how-to articles, market development news, and such resources, these niche directories could add even more value.

Making Plastic – Plastic Moulding

Ever wondered how plastic is moulded into the exceptionally useful things that we employ in our daily life? Is it as simple as melting plastic and lathering the sides of a mould with it and cooling it, much like chocolate? The answer, actually, is no. Moulding plastic is a little more complex than that. Plastic is made using a process often called plastic injection moulding.

What is this type of moulding

Plastic injection moulding is the method of manufacturing parts made of thermoplastic and thermosetting plastic by melting and forcing into moulds where they cool to form the desired object.
How does plastic injection moulding work?

The process of plastic injection moulding usually begins with an industrial designer or engineer who designs a product. This is followed up by the work of a toolmaker or mould maker who makes the mould to fit the design created. These moulds are metallic and usually made using either steel or aluminum.

Using machines, they are made to acquire the exact shape desired by the design. Once this is done, the process of actually making the plastic follows. This involves thermoplastic and thermosetting plastic being fed into a heated barrel and mixed. This melted material is then forced into the cavity of a mould and there it cools and hardens to form the desired part.

Some characteristics of the process:

1. I uses melted and mixed thermoplastic or thermoset plastic as the base
2. It uses a plunger which acts like a screw or a ram to force the melted material in the mould
3. It makes a shape that is open-ended and has taken the shape of the cavity of the mould
4. It shows a parting line and gate marks on the finished products and the ejector pin marks can also usually be made out

Some history

Alexander Parkes invented plastic in 1851 in Britain. This was worked on and bettered by John Hyatt, an American inventor in 1868. He also patented, in 1872, the first injection moulding machine. In the 1940s, the need for mass production of plastic products increased and saw the invention of the first screw injection machine by inventor James Hendry of America. This increased not only the speed of production but also the amount of precise control that could be exercised on the finish of the product.

Since then, this type of moulding has been used widely in the production of everything right from milk cartons to entire car panels and automotive parts. Since it is not a very costly material, it is best suited for mass produced goods.

Advantages of this type of moulding:

1. The rate of production are very high and therefore mass production is much benefitted
2. Since tolerance levels are high, they can be repeated
3. The labour cost is very low
4. The losses in scrap are very minimal
5. The products require very minimal finishing
6. A wide range of materials can be used

Disadvantages using this type of moulding:

1. Although labor expense and scrap loses are minimal, the cost of equipment and therefore investment is high
2. The running costs have the potential to be high
3. There is also need to design the correct parts

The Processible Plastic for Mold Making

1. Introduction
The processible plastic — Hongke material is a fundamental casting material with high density, high precision and high stability and is suitable for cutting in high speed. It is widely used abroad in aviation, navigation stage properties, and electrical appliance where high quality mold and module are required.
Concurrently, only few countries in the world are able to produce this kind of processible plastic. With the development of high technology, the demand for high quality mold with a complicated curve shape, and difficult technique in manufacturing is increasing, As a result of their own limitation, the traditional casting material such as plaster, paraffin and wood etc, can not realize CNC numerical control rnanufactuimg and satisfy the need for development. Therefore the processible plastic replaces the primeval mold making material. Particularly in the 90’s, with rhe spread of numerical control manufacturing technique, the phenomenon is even more outstanding. In early 80’s, similar materials has been invented for smiuktmg cutting arid mold making on numerical control machine, but in our country this kmd of material relied totally on import until 1997. This fully demonstrated the importance of this kind of material for our mold making industry. For example mold making,casting mould,plastic injection mold etc.According to statistics, till April 1998, we have already 400 set of numerical control center (5 axises, 5 axises) of our mold making industry. It showed product simulating cutting requiring processible plastic. The demand is evident. As specified in 95 national plan, the annul output after 2000 of automobile will reach 2 million 7 hundred. Some 175 to 440 kinds of basic body type of automobile will leave for renovation and reform. The cycle for automobile type renewal is 6-10 years in our country. In the foreseen years the processible plastics will be used more extensively in life. Therefore the processible plastics – Hongke plastics is produced to meet the demand, its performance index has already reached the international standard for likewise products.

2. Develop of the product
At the moment, only few countries are able to manufacture processible plastics worldwide. Before 97, china has spent over tens of millions US dollars on this material. To produce and nationalized the material and to cut the cost and replace the import products become urgency. It’s a common knowledge that mold-making industry is the mother of modern industry. It is a significant symbol of industry development of the country. One cannot separate the development of mold material when talking about mold making. In the recent years, our mold making industry is transiting into modem industry development, CAD/CAM technique, numerical control manufacturing are widely used, consequently the requirement for the mold material is higher. Once a technician of a famous mold workshop discuss with us about producing a kind of basic casting material for high speed cutting on the numerical control machine, which should not be transfigured by the process,
of which the amount of abrasion of the knife should be low, and doesn’t absorb moisture
and is antisepsis, with a sufficient degree of finish on the surface^ and be preservable over
long-term. The factory is allocated with CAD/CAM technique together with advanced
numerical control manufacturing center. But the so-called ” processible material” has been
relied on import, which is expensive to buy and gives a long cycle for supplying. Hence we
made a survey over the mold making industry, and the result verified that the material has
a potential huge market. At that time, no such material was available nationwide, it is totally
relied on import. Therefore Honke material co. Ltd. began to engage itself on the research
and development of the material, during the formulation of the prescription, through
selecting various chemical structure of macromolecule to adjust, modify, and add ancillary
preparations and filling, can prepare double component mash like material and panel
material of different high and low density and performance index. When basal material is in
the basic system of macromolecule, add different modification monomer material of all
conditions, such as elasticizer, activator, and filling etc can greatly improve the
technical performance of the processibel material. Below is a brief description at initial period of matching the material and reaction procedure.
