Molding and Processing Technologies



Please imagine a meat grinder. PVC resin is fed to the cylinder via the hopper. The shaft (which is called "Screw") in the cylinder is rotated to push resin forward. Resin is melt by heat and kneaded, while it is pushed forward, and then extruded from the outlet dies. This machine is called "Extruder". The technology is suitable for production of film, sheet, tube or pipe by selecting a suitable die as the case may be.
