Nitrogen Gas Molding
Custom Gas-Assist Molding for Lightweight, Complex Part Designs
Our nitrogen gas-assist molding process enables the creation of strong, lightweight parts with complex geometries and minimal warpage.
Strength and Efficiency Through Nitrogen Gas-Assist Molding
Lomont Molding offers advanced nitrogen gas-assist molding services that improve strength, reduce part weight, and eliminate common molding issues such as sink marks and warp.
This low-pressure process injects nitrogen gas into thick sections of the part during molding, displacing material and forming hollow areas that maintain structural integrity while saving material. It’s ideal for creating large, complex parts that demand both rigidity and weight savings.
Gas-assist also allows faster cycle times and reduced stress in molded parts, making it a go-to solution across industries like furniture, medical equipment, consumer products, and industrial applications.
Gas-Assist Molding Capabilities and Common Uses
Material Efficiency
By hollowing thick sections with pressurized nitrogen, gas-assist molding saves material while retaining part strength.
Improved Surface Quality
Reduces cosmetic defects such as sink marks and warping in large or thick-molded areas.
Design Flexibility
Enables designers to include thick ribs or structural elements without overpacking or increasing cycle times.
Ideal for Large Parts
A great fit for furniture frames, appliance panels, handles, medical equipment housings, and more.
Key Advantages of Nitrogen Gas Molding
Lightweight Strength
Forms hollow sections inside thick areas, providing excellent structural integrity with less weight.
Lower Material Costs
Less resin is required thanks to nitrogen displacement, reducing overall part cost.
Shorter Cycle Times
Faster cooling and ejection cycles allow for higher throughput and improved productivity.
Minimized Warpage and Sink
Gas pressure ensures more uniform part cooling and material distribution, improving consistency.
