Single wall corrugated pipe extrusion line: It mainly uses PE, PP, PVC as raw material, through the corresponding moulds inside and outside produces smooth uniform corrugated pipes. The forming blocks made of hard steel, dealed with a rigorous use of CNC finishing materials produced to ensure that the hardness of the molding module and precision molding machine for the closed structure, module link in the overall closure base, in forming do from the running tunnels. Produced pipes by the production line are mainly used in wire and cable products threading pipe, washing machine drains, vacuum cleaner, ventilation pipes, tubes, etc. Wooden cases and wooden pallet
