Process flow
Raw material →vacuum feeding →material dryness →single screw extruder →spiral mold →low temperature cooling calibrator, high level water tank →water cooler→ dip-in vacuum calibration tank→ dip-in cooling water tank→ dip-in cooling water tank→ spray-code printer→ belt haul-off→ double winder→ finished product inspecting & packing
