[ Jiuzhi Plastics News] In recent years, China's injection molds have developed rapidly in quality and quantity, but compared with foreign advanced technology, the technical level of most enterprises in China still needs to be improved. At present, compared with the advanced technology level of foreign countries, China's injection mold industry mainly has the following problems.
The contradiction between supply and demand is difficult to solve
The domestic market acceptance rate of injection molds has been less than 74%, of which large, precision, long-life molds have lower satisfaction rates. At present, molds in industrialized countries are accelerating their transfer to China, and international procurement is increasing. The market demand is strong, production development is still difficult to keep up with, and the situation of short supply will continue for some time.
Unbalanced industrial development
Although the products of individual enterprises have reached or are close to the international advanced level, overall, the accuracy, production cycle and service life of the molds are still far from the foreign countries, and the overall level of industrial development is low.
Overall, the level of technology is backward
According to the molding characteristics, the injection mold is divided into two types: thermosetting plastic mold and thermoplastic plastic mold; according to the molding process, it is divided into plastic mold, blow mold, casting mold, thermoforming mold, hot stamping mold (compression molding), injection mold, etc. The hot stamping die can be divided into three types: overflow type, semi-overflow type and non-overflow type. The injection mold can be divided into cold runner mold and hot runner mold by the pouring system; Can be divided into mobile, fixed two.
