Precision injection molding refers to an injection molding method in which precision is very high, it is difficult to achieve required injection using a general-purpose injection machine and a conventional injection process compared with conventional injection molding. With rapid development of polymer materials, engineering materials occupy a certain position in industrial production. Because of its light weight, resource saving and energy conservation, many industrial product components have been replaced by engineering plastic parts. Precision molded plastics are widely used in industrial products such as instrumentation, electrical and electronic, aerospace, communications, computers, automobiles, video recorders, and watches.

In recent years, mould manufacturing costs have continued to rise, so whenever we always discuss topics such as how to reduce mold cost. Therefore, this paper tries to analyze various aspects of mould manufacturing, in order to reduce cost of mould manufacturing.
Before drawing master assembly drawing, process drawing should be drawn and conformed to requirements of part drawing, process data. Size guaranteed by next process shall be marked with words "process size" on drawing. If no other machining is performed after molding except for repair of burrs, process diagram is exactly the same as workpiece drawing.
Germany is one of the first countries in Europe to produce molds. Its mould manufacturing technology and quality have been recognized by users all over the world. It is well-known in the world and is one of the most important high-end mould suppliers in the world. After years of practice and exploration, German mould manufacturing companies have formed a consensus: whole industry must be coordinated, teamwork, technological innovation, learn from each other's strengths, make progress together, and play a good overall advantage to achieve industry success.
Mold is an important process equipment in material forming processing. Products that can be produced often have many times value of mold itself, and mold can easily mass produce a large number of parts with value and satisfying quality requirements. Therefore, molds are widely used in machinery, electronics, automotive, information, aviation, aerospace, light, military, transportation, building materials, medical, biological, energy and other industries. About 60%-80% of parts and components in above industries rely on injection moulding process.
In metal processing and manufacturing industry, everyone should be familiar with WEDM-LS, WEDM-MS and WEDM-HS. They all refer to WEDM machine, which are widely used in mould manufacturing industry. So what is difference between these three processing technologies?
Since 2000, global mould industry has been steadily rising, with an average growth rate of more than 5%. By 2017, global mould industry market has reached 200 billion US dollars. In developed countries such as United States, Germany and Japan, automotive-related mold demand accounts for more than 50% of total mold demand, and global automotive molding market has exceeded $55 billion. In this fierce competition and rapid development, global automotive molding manufacturing industry has seen nine major development trends.
