1. Clamp the mold to the edge of the row cavity
2. Injection of molten plastic
3. Compression injection into molten plastic
4. Cooling and stripping
The moving model pushes the entire cavity and completes the pressure-holding action
The pressure established in the cavity is evenly distributed on the surface of the product
Greatly improve the precision and dimensional stability of the surface of the product
Low internal stress during injection molding, suitable for parts with high transparency requirements
