What's the difference between injection molding machine and blow molding machine?

The difference of materials used in injection molding machine and blow molding machine;

Injection grade materials for injection molding machines and blow grade materials for blow molding machines.

Injection molding machine and blow molding machine are two different processing machines. In the process of producing products, the temperature adjusted by the machine is different. If the material is returned for other processes, it will do great harm to the mold and the machine! It is not recommended to use returned materials for products with two different processes!

Even if it's the same, it's all made of pet. It's different. One is the injection stage, and the other is the blow molding stage, which is used for injection molding machines and blow molding machines. If there is electroplating, it is electroplating grade. Therefore, the physical properties of these two materials are different, and the tensile properties of injection grade are not as good as those of blow molding grade, so injection grade cannot be used for blow molding.
