Factors Affecting Injection Molding Process

Plastic varieties: During the molding process of thermoplastics, there are volume changes caused by crystallization, strong internal stress, large residual stress frozen in the plastic parts, strong molecular orientation and other factors. Therefore, compared with thermosetting plastics, their shrinkage rate is larger, the shrinkage rate range is wider, and the directionality is obvious. In addition, […]

The ten most common injection molding processes for plastic molding

Injection molding: also known as injection molding, its principle is to add granular or powdered raw materials into the hopper of the injection machine. The raw materials are heated and melted into a flowing state. Under the push of the screw or piston of the injection machine, they enter the mold cavity through the nozzle
