Advanced Large Part Manufacturing Technology
Structural foam molding is an advanced process that creates lightweight yet exceptionally strong plastic parts, making it ideal for large part production. At Norco Plastics, we achieve structural foam components using our high-pressure injection molding machines with specialized foaming agents that create air bubbles when heated, forming a cellular core with a solid outer skin.
Our large tonnage injection molding capabilities are perfectly equipped for structural foam parts, combining high clamping force up to 2800 ton with precise control of injection pressure and plastic melt flow. Unlike traditional low-pressure structural foam machines that use nitrogen injection, our high-pressure process with foaming agents delivers superior results through our conventional injection molding equipment. This advanced approach allows us to manufacture large plastic components with excellent dimensional stability, reduced material consumption, and enhanced structural integrity.
For applications requiring both size and strength, structural foam molding offers the ideal solution by creating large parts with thick wall sections without the sink marks, warpage, or excessive weight typically associated with conventional injection molding processes. The large tonnage process enables consistent structural foam molding quality across complex geometries and challenging design requirements, all while utilizing our high-pressure injection technology.
