Key Benefits Of Structural Foam Molding

bg2

Structural foam molding is a widely used low pressure injection molding process in which an inert gas is injected into melted polymer for the purpose of reducing weight and density of the end product while enhancing its strength. The lower pressure and forces involved in the process allow more economical molding equipment to be utilized resulting into high productivity of very large parts or producing multiple parts on a single machine in a single cycle comparatively lower price in comparison to the conventional injection molding.

The structural foam injection molding process utilizes a molten resin that has been injected with a chemical blowing agent or nitrogen gas. This blend is then injected into the mold, where the gas or the agent expands and efficiently fills the mold with foam. The surface cells collapse, when the foam flows through the mold, producing solid skins against the walls of the mold. The core of the part remains structurally foamed.

The overall weight of the part is reduced by up to 20 percent as the outer skin is solid and the center of the wall is foam. The parts made with this process are sturdier and thicker than any other processes and have minimal warpage.
