High-magnification foam mold technology
-Challenge- Pursuit of further weight reduction for EVs
Foamed plastics are increasingly adopted as a material that contributes to energy saving and weight reduction of automobiles.
For instrument panels and door trims, it is required to achieve both light weight as well as texture in terms of surface design and a pleasant feeling to the touch.
-Solution- Lightweight by foaming technology
Injection foam molding technology of PP resin is used to form the core (foamed) layer and the skin layer.
SEKISUI’s proprietary technology enables high-aesthetic appeal, high-shock resistance, and high rigidity, while reducing weight by 25-35% compared to solid resin parts.
