Gas Assist

Gas-assisted injection molding

This service is for large, dense parts that are made with a hollow inside.

Used in cost saving initiatives for weight reduction and cycle time reduction. Process strength in all 4 facilities with the know how to update to any facility in a matter of days. Thomson has the infrastructure to feed the Nitrogen gas to any injection molding machines directly vs. bottle that creates its own safety and process concerns. In our GA and NC plants, investment previously made for a 1500 Gallon external tank that allows for the proper infrastructure. Investment made in 2021 of $500,000 to improve high pressure gas control equipment that includes diagnostic information through USB data transfer.

Decades of experience as a leader in gas assist molding.
