GIT (gas-assisted molding) & Vacuum Molding

Gas-injection and vacuum molding — strong, light, sink-mark-free parts

Thick walls, handles and frames that have to be strong and light — where standard molding leaves sink marks, warpage and trapped air.
Gas-assisted (nitrogen) molding blows a hollow core through the thick sections, while vacuum-assisted molding pulls the air out of the cavity before filling.
The result: stronger, lighter parts with no sink marks or burns — at lower pressure and a shorter cycle.

  • Gas (nitrogen) creates hollow sections — stiff & lightweight
  • No sink marks, low injection pressure, less material
  • Vacuum removes trapped air — no burns or bubbles
  • Better weld lines, faster fill, shorter cycle

How it works

Gas-assisted (nitrogen) molding

We inject the plastic, then high-pressure nitrogen pushes a hollow channel through the thick sections. That cuts internal stress, removes sink marks and saves material — at low injection pressure, with less warpage, and with gas-reinforced ribs that add stiffness without adding weight.

Vacuum-assisted molding

Once the mold closes, we pull the cavity down to a vacuum and then inject. With the air gone, the cavity fills easily at lower pressure and higher speed — no trapped air, no burns or bubbles, cleaner weld lines and a shorter cycle.
