Molds are templates used in the production of many products, and can be produced and manufactured according to the different needs of many products. According to different products, the design of molds can vary greatly, while their main structure is basically the same. The mold is mainly composed of a pouring system, a temperature control system, molded parts, and structural parts. The pouring system and molded parts are the parts that come into direct contact with the plastic and vary with the plastic and the product. They are the more complex and variable parts in the mold, requiring high processing smoothness and precision.

In this process, its shaping is mainly based on the design requirements of the product. By using such molds, many production processes of the product can be reduced, and it can be molded in one go

Contradictions and obstacles in the development of China's plastic mold industry

The requirements of modern industry for injection molded parts are not only high precision, but also good internal quality. In order to meet these requirements, it is necessary to develop and utilize new injection mold technologies. Currently, new injection mold technologies introduced from abroad are gradually being promoted and utilized in the southern coastal areas, which have played a significant role in improving the quality of injection molded parts. In recent decades, the domestic plastic mold industry has developed rapidly, and the demand and requirements for talent have also become increasingly high. But it is still difficult to solve this thorny problem domestically, which has become the main obstacle to the development of China's mold industry.

It is understood that there are varying degrees of difficulty in recruiting personnel in mold production areas along the coast. In order to attract talents, many local mold companies even recruit across regions, provinces, and cities. Three types of talents make up the mold industry. The "golden collar layer" personnel are proficient in mold design software and mold structure knowledge, and have accumulated a lot of practical experience in their actual work. They are very suitable for serving as technical leaders or technical supervisors in various enterprises. The "gray collar layer" refers to personnel who specialize in designing and processing molds in their positions, accounting for 15% of the mold technology positions in enterprises. Blue collar workers "refer to technical staff responsible for the specific operation and daily maintenance of molds in production positions, accounting for 75% of enterprise positions and currently the largest demand. This has become one of the main obstacles in the domestic mold industry, and strengthening the training of professional talents is an urgent matter for the mold industry.
