There are many kinds of molds and there are many classification methods. Usually, molds are divided into stamping molds, plastic molds, casting molds, etc. according to different processing objects and processing techniques. In recent years, with the continuous development of the plastics industry, especially the modern new material industry such as engineering plastics, and the enhancement of public awareness of energy conservation and environmental protection, plastic molds have also been fully developed as an important basic molding tool for the production of plastic products.

Plastic molds rank first in my country's mold import and export. According to statistics from the General Administration of Customs, my country's total plastic mold imports in 2019 were 870 million US dollars, accounting for 44.87% of the total mold imports; plastic mold exports totaled 3.967 billion US dollars, accounting for 63.51% of the total export value.

"Scientific energy conservation and emission reduction, taking the road of low-cost development" has become a long-term development trend in various industries, and "replacing wood with plastic" and "replacing steel with plastic" have become one of the important ways to save energy and reduce emissions, especially in the automotive field. On the other hand, with the further tightening of global emission and fuel consumption regulations, the weight reduction of automobiles has become more and more realistic. It is foreseeable that the market share of plastics in the field of automobile materials will further increase, thereby creating a good market environment for plastic molds and application categories. and the scope will be further expanded.
