Low-density foam sheets are used as a raw material for a wide range of products, including building materials, automobiles, home appliances, and daily necessities. We develop and sell multi-layer and high-foam multi-layer sheet manufacturing equipment. We also manufacture foam extrusion lines that use CO2 as the main foam medium. Thise "tandem extrusion system" can cover a wide range of foaming ratios by connecting two extruders, one for kneading the resin and additives while with the other for cooling them.
