Cell Molding
- Target : C/Stand, C/Rear : Lightweight (25%↓), zero bending, zero deformation, high-quality appearance
-
-
Cell MoldingHigh diffusion rate of supercritical fluid (SCF) Increased mobility of plastic molecules (30%↑ flow rate)
-
Core BackAfter the first injection molding is completed, the mold is core-backed with a certain pitch to complete the molding (lightweight)
-
Counter PressureMolding with internal pressure maintained at 40 Bar or higher (Air Pusher Controller)
-
Equal & Speed CoolingUniform heating, cooling 3D H&C structure mold design, processing and manufacturing
