What does gas-assisted injection molding do?

Gas-assisted injection molding is a special injection molding process, whose main purpose is to improve the appearance quality, dimensional accuracy and mechanical properties of plastic products by injecting high-pressure gas or low-pressure vacuum.

1. Several specific functions of gas-assisted injection molding process:

Remove bubbles: During the injection molding process, bubbles will be generated in plastic products due to various reasons, and the use of gas-assisted injection molding technology can expel air from the mold to avoid the generation of bubbles.

Improve dimensional stability: The gas-assisted injection molding process can form a balanced airflow inside the mold, so that the plastic material is evenly distributed and the dimensional stability of the molded product is improved.

Improve surface finish: This process can eliminate burrs and marks caused by extrusion, make the product surface smoother and smoother, and improve the appearance.

Reduce looseness: By increasing the air pressure or reducing the vacuum, the contact force between the plastic and the mold can be increased, thereby reducing the looseness.

Optimize detail structure: Gas-assisted injection molding can also optimize the product detail structure by changing the direction and flow of the airflow, and improve the mechanical properties and use effect of the product.

In summary, gas-assisted injection molding technology is an advanced plastic processing technology that can greatly improve the molding quality and appearance of injection molded products and improve product performance and competitiveness.
