Development status of mold industry: |
Types of molds and development process: |
Molds are indispensable process equipment for modern industries, especially automobiles, aviation, electronics, electrical appliances, instruments, instruments, weapons, daily necessities, etc. 80%-90% of the products produced by these industrial sectors rely on molds shaped. Mold technology directly restricts the development of manufacturing, product upgrading and competitiveness.
As the foundation of equipment manufacturing industry, mold is known as the "mother of industry". 75% of rough-processed industrial product parts, 50% of finished parts, and most plastic products are processed by molds. As the basic industry of the national economy, molds are involved in various industries such as machinery, automobiles, light industry, electronics, chemical industry, metallurgy, building materials, etc., and are widely used. The upstream of the mold industry mainly involves two industries, namely materials and mold processing tools. The need for advanced machining tools has been urgent in recent years. The ratio of investment in fixed assets to the growth of mold output in the mold industry is 1:1.2 on average in the entire industry. If the sales of the mold industry increases by 40 billion yuan, it means that the demand for mold processing equipment has reached 50 billion yuan. |
Generally, plastics, rubbers, metals, glass or minerals are subjected to high temperature, high pressure or high impact to form objects of a certain shape. Molds are often used to produce products in large quantities. Therefore, molds have become an indispensable tool. Therefore, the development of the mold industry It can not only improve the output and precision of industrial products, but also drive the technological progress and competitiveness of the manufacturing industry.
The mold is classified according to the molten state of the molding material:
