The first is the development of the production of plastic products based on the design of plastic mold, plastic mold is a basic tool for a production of plastic products, mold precision directly affects the accuracy and completeness of the structure and size of plastic products. All kinds of plastic products are required to go through the design and manufacture of plastic mold, injection molding and surface treatment process, the precision mold complex structure, high surface quality and technical standards, is technology and capital intensive products, the production process requires the application of high speed machining and ultra precision machining technology, rapid prototyping technology, automatic control technology, polymer application of materials processing technology, involving machinery, metal materials, polymer materials, chemical materials, electronic and electrical, automation control, high comprehensive technology.
1. General Situation of plastic products industry
Plastic is made of synthetic or natural polymers as raw materials, such as plasticizers, fillers, lubricants, injection agent and other additives as auxiliary components, made of plastic material and a small amount of solid material under certain temperature and pressure. Plastics are widely used in modern society due to their light weight, strong plasticity, low manufacturing cost and wide functions. At present, the synthesis of polymer materials has become an indispensable new materials with iron and steel, wood and cement together constitute the four basic materials in modern society, supporting the development of modern society is one of the basic materials, widely used in information, energy, industry, agriculture, transportation and other areas of the national economy. In recent years, the rapid development of China's plastic products industry, the scale continues to expand, has become an important part of China's national economy.
2. General situation of mould manufacturing industry
Mold is a plastic, rubber, metal, powder, glass, glass fiber reinforced plastic and other materials processed by processing equipment of the basic process equipment, belongs to the production process of intermediate products, for the final product production. Die processing is one of the important ways of material forming, compared with mechanical processing, has less process, high material utilization rate, low energy consumption, easy production, high efficiency advantages, so it has been widely used in automobile, energy, machinery, electronics, information, aerospace industry and daily life. According to statistics, 75% of rough machining of industrial products, 50% of the finishing parts by the mold, 80% of the household electrical appliance industry, parts of the mechanical and electrical industry more than 70% of the parts also need to go through the mold processing. Mold industry can often lead to the development of related industries, therefore, mold industry is often referred to as benefit amplifier.
