Our Gas-Assisted Injection Molding Process
The process begins with the injection of molten plastic under high pressure into the mold cavity.
After the material fills the cavity, a controlled gas (usually nitrogen) is injected into the molten plastic, creating hollow sections within the part.
The gas expands, pushing the plastic against the mold walls, helping to form the part's outer shape while reducing material use.
The plastic begins to cool and solidify, with the gas helping to control the cooling rate and reduce internal stresses.
Any excess gas is vented out of the mold cavity to prevent pressure buildup and ensure the part’s integrity.
Once the part has cooled and solidified, it is ejected from the mold ready for further processing or finishing.

Ensure Even Wall Thickness for Complex Part Designs
Gas-assisted injection molding ensures even material distribution by injecting gas into the mold cavity during injection. This gas forms a hollow core, which reduces the material volume and allows for more consistent flow. The technique helps prevent common defects such as sink marks or warping by maintaining uniform thickness across complex geometries or varying wall sections. By reducing internal stresses and promoting material uniformity, this method improves the overall structural integrity of the part.
