Plastic sheet production line is a kind of plastic machinery. Sheet machine, sheet production line, sheet equipment, sheet extruder.
1.PVC plastic sheet production line preheating: This is the boot before the mold heat action, need to preheat to mold heat.
2. Clamping: opening and closing mold reasonable adjustment, is conducive to improving product stripping and product feed effect.
3.PVC plastic sheet production line preheating: steam into the solid mold, the mold preheating, so that the mold is preheated at the same time, will remain during the condensate and cold air discharge. Role: to improve the mold temperature, to enhance the apparent product melting degree.
4. Through the heating: to improve the product core, the internal sintering. Penetrate heat consumption, waste steam more serious.
5. Both sides of the heating: to further enhance the heating effect, improve product surface quality.
6. back to temperature (insulation): all valves closed, make full use of mold waste heat, so that the product heat insulation. Is conducive to product surface sintering, can better save energy (steam).
7 vacuum cooling: vacuum valve open, vacuum pump vacuum. So that mold and products within the waste heat and water all emptying, remove part of the blowing agent, to avoid product swell. So that the formation of negative pressure within the mold, is conducive to product stripping.
