N₂ Supply Solutions for GAIM

PLASTINUM Gas-Assisted Injection Molding with N₂

Taking process efficiency and quality to the next level by using nitrogen (N₂) to mold plastic parts - with highly efficient, dedicated high-pressure N₂ supply solutions from Linde

Importance of Gas Purity for GAIM

Gas-assisted injection molding - also known as gas injection molding (GIM) - with N₂ is a proven, well-established process to produce hollow parts or parts with hollow sections. It enables you to manufacture lighter plastic components with higher dimensional accuracies. High-pressure nitrogen shapes a hollow or channel in a molded plastic part. The nitrogen forces the melted mass out from the core of the component and presses it against the mold surface. After solidification, the gas is released from the cavity.

Gas purity is important in GAIM with N₂. High-purity gas stops the plastic from oxidizing under high temperatures and gas pressures. Our cost-effective supply solutions for high-pressure nitrogen with low oxygen and no oil content enable you to produce parts at lower cost and with less scrap and downtime.
