By mixing N₂ or CO₂ gas with the molten resin and injecting it into the mold, the weight of the product is reduced and warpage and sink marks are improved.
There are two types of foam molding: physical foaming and chemical foaming. In recent years, the adoption of physical foam, which has a low environmental impact and is applicable to super engineering plastics and recycled materials, is advancing.
JSW sells and tests "MuCell® specification machine" and "SOFIT® specification machine" as a physical foam injection molding machine that combines physical foaming technology and our original screw technology.

Molding example : Panel
The physical foam molding of bioplastics greatly contributes to carbon neutrality.
Foam molding causes an appearance defect called swirl mark, but it can be prevented by using the counter pressure method (CPM).
