The Advantages of Plastic Mold

Plastic mould is a king of tool used in plastic industry to shape the plastic products and to measure their accurate size. In recent years, with the rapid development of plastics industry and the constant improvement of engineering plastic materials, the range of application of plastic products is being extended gradually, providing a vast market for plastic mould. According to different methods of forming, plastic mold can be divided into many categories, such as plastic injection mould, plastic compression mould, plastic extrusion mould, plastic blow mold and so on. Here are different types of plastic moulds for your choosing:

China’s plastic mould has formed a huge industry chain, ranging from raw material processing, inspection equipment to automobile, home appliance, electronic communication, construction and building materials, as well as many other industries. It is estimated that there is a need for plastic mould of about RMB 10 billion just in automobile and motorcycle industry. In the future mould market, plastic mould will have a rapider development rate than other moulds, also a bigger share of the market and prosperous future.

So compared with the traditional metal mould, what is the advantage of plastic mould? How could plastic mould become so popular? The reasons are as follows:

Firstly, plastic mould performs excellent stability, and its corrosion resistance is what common metal mould can hardly do. Especially polytetrafluoroethylene (PTFE), commonly known as “the king of plastic”, its chemical stability is even superior to gold, for it will not be corroded even boiled in the aqua regia for more than ten hours. The materials of Plastic mould have good heat stability, so the mould will have little change in size after heat treatment, which avoids reprocessing of the mould and to some extent ensures the accuracy of plastic mould.

Another feature of plastic mould is light weight and high strength. The hardness of plastic mould material is generally 50-60 HRC, after heat treating the mould has enough surface hardness and rigidity, which can endure the compression stress and frictional force in the process of filling plastics. So the plastic mould enjoys good abrasive resistance and longer life span.

What’ more, plastic mould is relatively cheaper than metal mould, and easy to be recycled. On the other hand, plastics are electrical insulators, and enjoy high security, so they are widely used in molding and machinery industry.

From the above statements, we know the benefits of plastics, and believe that plastic mould will become more and more popular in our daily life. Now, many mould manufactures or china mould suppliers are devoting themselves to plastic mould industry, to produce better and higher quality plastic mould products.
