Summary of the Historical Development of PET bottle embryo

Compared with the forming die of ordinary plastic products, the PET bottle embryo group cavity mold has the inherent characteristics of high precision and low rigidity. The price of a set of PET bottle embryo group cavity mold is even higher than that of the mainframe. Therefore, the mold closing mechanism must be able to play a good role in protecting the mold. 

In order to achieve this function, the mold closing mechanism must have sufficient stiffness, excellent mold locking and opening speed characteristics, uniform formwork deformation and good deformation repetition accuracy.

PET bottle embryo injection molding equipment is a high-end equipment, the idea of development is different from the development of ordinary injection machines. Some domestic units take the research and development of PET bottle embryo injection molding machine as ordinary medium-and low-end products, and change the screw barrel as a PET injection molding machine, which has embarked on a wrong route from the very beginning, so it is always hovering at the low-end level. 

First of all, it is necessary to correct the development idea and develop the PET bottle embryo injection molding machine as a high-end product in order to develop a high-performance PET bottle embryo injection molding machine adapted to the market. 

With the development of hot runner technology, the development of group cavity mold, especially the geometric growth of the application of PET bottle, put forward higher and higher requirements for the performance of PET bottle embryo injection molding machine. In order to adapt to the development of the market, the mechanism and structure control of PET bottle embryo injection molding machine further reflect the performance characteristics of special injection molding machine, mainly in the aspects of high speed, high efficiency, precision and so on.
