Graphite mold industry analysis

1, Mold introduction

Mold in the use of basic technology and equipment of industrial production is very common, mold industry is the basic industry of the national economy. In the industrial production of modern enterprises, the parts of the product can generally use different stamping, forging forming, die casting forming, extrusion forming, plastic injection or other forming processing methods, which are matched with the forming mold, so that the blank forming process can meet the requirements of Chinese product design parts. All kinds of tools and products used in our daily production and life, large machine tool bases, fuselage shells, small embryo head screws, buttons and shells of various household appliances are all closely related to molds. In recent years, the rapid economic development of the mold design industry, graphite materials, new processes and constantly increasing mold factories continue to impact the mold market, graphite with its good physical and chemical properties gradually began to become a better material for mold production in China.

2, Excellent performance of graphite mold

1. Excellent thermal and electrical conductivity; 2. Low linear expansion coefficient, good thermal stability, heat shock resistance; 3. Chemical corrosion resistance and most metals are not easy to react; 4. Cu matrix temperature at elevated temperatures (most of which are sintered at temperatures higher than 800 ° C). The strength increases with temperature; 5. Good lubrication and wear resistance; 6. Easy to process, mechanical design processing performance is good, can be made into a more complex shape, high precision mold.

3, Graphite mold processing technology

First of all, it is designed by the mold designer based on the product (part) of the use of the requirements of the mold structure, by drawing drawing, and then by the technicians in the field by drawing machining machinery (e.g., lathes, planers, milling machines, grinding machines, EDM, wire cutting, in each mold part and other equipment) holes, and then assembled and tested until it can produce a qualified product.

4, The status and development of graphite mold

Today, the graphite mold industry plays a vital role in the process of human life and development, and the development of many cultural industry management departments (such as mechanical and electrical, automotive, home appliance light industry, electrical instrumentation, communications, ordnance, etc.) needs to rely on the technology of the mold industry to improve and develop. Other countries in the world have invested a lot of human resources and financial resources to continue to develop and research the graphite mold industry.
