Structural Foam Molding Vs Injection Molding

Create thick and intricate parts and components without creating any depressions or sink marks.

Structural foam molding vs injection molding.

Structural foam molding is a process where the addition of a blowing agent and modification of process parameters creates a sandwich construction that has a solid skin on the outer layers and a foam core in center. Structural foam molding process. Two components for example polyol and isocyanate which are combined in order to create polyurethane are stored in liquid form in separate containers. Structural foam molding sfm is an injection molding process that is used to make strong durable and lightweight molded plastic products.

Structural foam allows a range of thickness from 1875 to 5 while injection molding is generally limited 06 to 1875. Structural foam molded products have cellular cores surrounded by rigid integral skins. Structural foam molding can result in higher quality products than traditional injection molding in some cases. Perhaps the best way to explain the difference between the two methods is to describe structural molding and its benefits.

Since it consumes fewer resources structural foam molding is more efficient and less expensive than other injection molding processes while delivering similar results. Structural molding produces high strength parts that are lighter. Structural molding shares some similarities with injection molding but these are the main differences between the two processes. Products made with structural foam molding can even be used in place of concrete sheet metal fiberglass or wood.

Our focus is injection molding machines structural foam machines extrusion machines and wet paint systems. Thicker wall sections while both structural foam and injection molding offer variable walls it s structural foam that gives you the most flexibility and the thickest wall sections. The structural foam molding process vs. 2r automation llc provides controls and hydraulics expertise for plastics machinery.

The springfield name remains from the machines. Original creator springfield cast products which was bought by hoover universal in 1975. Structural foam injection molding. Briefly structural foam molding is the method used to process.

Foam molding technology the structural foam process is a low pressure injection molding process where an inert gas is introduced into melted polymer for the purpose of reducing density and hence weight of the finished product. Their weight can be reduced by 10 to 30 in comparison to injection molding parts without affecting structural integrity.
