Plastic mold has been developing about 40 years. It occupies a very important position in the plastic molding process. Plastic mold plays a very important part in the mold industry. Mold production technology is also a one of the important symbols of a country's level in manufacturing process. In the international community, in order to make industrial molds for better development, some countries have propped up the relevant policies. Such as Japan developed a mechanical production of revitalization and make mold as a specific product to be developed in the 80-90 age. The United States has more than 10,000 mould of professional manufacturers the late 1990s. The total output value was more than 100 billion dollars.

In China, the design and yield of mold has been done from 100 years. The proportion of plastic mold in the import and export is as high as 50% to 60% these years.It becomes a comprehensive science and technology. At the same time, people has more and more understanding of polymers and the manufacturing process of the various parameters and change more and more in-depth understanding. The design of mold comes to a new stage as a means of quantify and simulation computer-based. Compared with plastic mold CAD/CAM and the traditional design methods, not only quality, speed and precision but also the mold manufacturing methods and productivity has a significant leap forward. China can supply plastic mould for kinds of pipe fittings, such as PPR PVC PE PB ABS…to the world.The features of molds: high precision, extended service life, short lead time, competitive price, prompt delivery and excellent after-sale service. Since china entered to WTO, it has brought great challenges and brought more opportunities for the plastic mold industry. There is a great advantage on the price because the plastic mold is Zhong Didang products mostly in china. Some products even sell 1/5 to 1/3 on the price of foreign products.

Foreign products impact domestic products weakly, while domestic products are increased in export volume. The High-precision molds were relied on imports mainly before our country entering WTO. At now days, not only highly sophisticated product imports have more convenience, and also encouraging more foreign investment to build factories in China, bringing advanced foreign technology and management experience in mold. The mold of professional training in China has played a role in promoting talent. China's government has worked out relevant policies to promote industrial development rapid prototype. On China's actual situation, we should reduce custom about the product that we couldn't plastic mould independently and perform related preferential policies well. We can accelerate the development of the industry and progress by police guidance.

With the development of the market, the diversification of molding methods and new plastic materials would be developed in the future. In order to meet the needs of the market, whether plastic mould species, structure, performance or processing are bound to faster development. What's more such a rapid prototype development must keep pace with the times.
