Plastic & Pla Biodegradable Sheet Making Machine Plastic & Pla Biodegradable Sheet Making Machine is of Special Screw Type Designs, three-roll calendering method, turn-key project include formula. Process principle: Dehumidifying drying crystallization system–Parallel twin screw extruder(raw material melt foaming plasticizing)—Quick Change Filter—Melt Pump—T-Die Mold—Three-Roll Calender—Cooling Device—Coated Silicone oil system—Trimming Device—Traction—Automatic Tension Winding
Advantage:
* No need Vacuum Drying Method:Conventional drying methods are prone to chemical changes (such as oxidation during the drying process), and the vacuum drying method can better maintain its original characteristics and reduce quality loss if using twin screw compound machine.
* Twin screw extruder melting system: better dispersion,clear and transportation sheet,suitable for more different types of materials. * Ultra high pressure vacuum systemon twin screw extruder to make sure the best quality sheet * Movable three-roll calendering system * Coated Silicone oil systemto remove the tooling easily when produce by injection machine. * Automatic Tension Winding
