HDPE spiral corrugated pipe making machine is a special equipment for the production of high density polyethylene (HDPE) spiral bellows. This kind of pipe has good strength and toughness because of its unique spiral structure, and is widely used in drainage, sewage and other engineering fields. The following is a detailed introduction to the HDPE spiral bellows production line
1. Production line composition
Extruder: used to melt and extrude HDPE raw materials into tubes.
Spiral mold: The molten HDPE raw material forms a spiral corrugated structure.
Vacuum sizing and spray cooling systems: ensure accurate tube sizing and rapid cooling.
Pull machine: pull the cooled pipe out of the production line.
Cutting machine: Used to cut continuously produced tubes to the required length.
2. Technical features:
·High efficiency single screw extruder with high speed.
High yield and good plasticizing ability.
·Unique design of spiral mold ensures uniform and beautiful spiral corrugated structure of pipe.
·Vacuum sizing system adopts multi-stage design to ensure pipe.
The size of the material is stable.
·Spray cooling system improves cooling efficiency and ensures pipe quality.
·Tractor adopts crawler structure, easy to operate and clamp
The holding system combines mechanical and pneumatic, making it more reliable.
·The cutting system adopts saw blade and planetary cutting mode, hydraulic feeding to ensure smooth pipe section, and is equipped with dust removal device to keep the working environment clean.
