Dongguan to the crown Plastic Products Co., plastic pipe factory use mechanical properties of PVC, electrical performance, strong acid strength, chemical stability, but low softening point suitable for the production sheet, wire and cable insulation, pvc drains, seals. In order to improve the fluidity of PVC, PVC to prevent the occurrence of bubbles, PVC plastic can be pre-dried. Drain die casting system should be chunky, large gate cross-section should not be there dead. PVC drain pipe mold to be cooled, chrome plated, so the use of screw-type injection machine nozzle injection melted PVC!
