PVC (PE) multi-hole pipe production line is applied to produce PVC, PE multi-hole pipes with the specifications of 3-hole, 4-hole, 5-hole, 6-hole, 7-hole and 9-hole. The line is also called plum blossom pipe or honeycomb pipe just because its section likes plum blossom. Due to its special multi-hole structure, the line adopts dedicated multi-hole integral die, equipped with high-speed mixing screw, and therefore its production speed and pass-rate of production are high and the inner and outside wall are smooth. The multi-hole pipes are mainly used in threading and laying optical cable, has the advantages of convenient threading, mutual interval, high anti-pressure, strong anti-freezing and good sealing etc. With strong impact resistance, anti-pressure and high toughness, it also achieves the characteristics of line pipe barrier isolation, easy operation, quick cable threading, good adaptability to operation environment and low project investment etc. The line is widely used in telecom, mobile, broadband network, military communications, railway, transportation and other communications pipeline. Unit characters: the unit can choose different types of main engine according to processing materials. PVC main engine adopts the conical twin-screw extruder, ensuring the plasticizing effect, high speed, and high pressure extrusion. PE main engine adopts efficient BM mixing polyethylene dedicated screw, ensuring high speed, efficient and precise extrusion. The multi-hole pipe die (PVC, PE) is designed specially based on the characteristics of the processing materials, which guarantees the stability of high-speed extrusion and the brightness and cleanness of the inner and outside walls. The tractor adopts imported variable frequency speed regulating, up and down drive method and has powerful traction to meet the needs of the unit's high-speed production.
