Influencing factors of the development of hollow blow molding

1. The technical level of the mold does not meet the requirements;

The blow molding mold is different from the injection molding mold and has its own characteristics. In the mold of the injection stretch blow hollow plastic molding machine, the key is the mold for injection parison. The material of the mold has special requirements for its performance, the coefficient of thermal expansion and contraction is small, the heat transfer efficiency is high, and the thermal conductivity is high. The structure of the mold is heat flow Tao form. Judging from the current level of mold technology in China, it is still impossible to develop and manufacture molds for injection stretch blow hollow plastic molding machines that meet quality standards. It is understood that some mold factories do not know which material is used for the mold of the injection stretch blow hollow plastic molding machine. How can they develop a mold?

2. The mold factory lacks input;

The lack of investment in the hollow blow mold factory has prevented the development of the mold technology level. It is understood that foreign mold factories that develop and manufacture injection-stretch-blow hollow plastic molding machines have their own injection-stretch-blow hollow plastic molding machines. The developed molds must be repeatedly tested on the host until they meet the requirements. However, there is no domestic mold factory that has purchased injection-stretch-blow hollow plastic molding machines as trial production equipment for the development of molds for injection-stretch-blow hollow plastic molding machines. "Stable quality, customer first" has always been our business purpose and philosophy. With excellent product quality and perfect pre-sale, in-sale and after-sale services, we have won the sincere cooperation and trust of customers, and customer satisfaction is always our goal.
