For municipal drainage pipe manufacturers, production speed directly affects profit and market competitiveness. The 3rd-generation water-cooled high-speed corrugated pipe extrusion line improves production efficiency by 20%~50% versus conventional equipment.

Proven Production Speed

1. DN110mm: Idle speed 8-12 m/min

2. DN300mm: Idle speed 6.95 m/min

Key Technologies for High-Speed Running

1. Aluminum Die Direct High-pressure Water Cooling + Dual Vacuum System Aluminum mould delivers 3× higher thermal conductivity than steel mould, doubling cooling efficiency to guarantee well-formed corrugations without deformation at high running speed. The forming machine adopts horizontal chain drive with dual vacuum shaping.

2. Dual Extruders & Double-layer Die Head Fitted with high-efficiency screws, max output reaches 300–400 kg/h. Uniform plasticization ensures stable extrusion under high-speed working conditions.

3. PLC Online Automatic Belling Automatic size adjustment via PLC runs synchronously with the whole line to reduce downtime and labor cost.

Excellent Compatibility with Recycled Materials

Pure HDPE tends to cause uneven inner wall due to high tensile strength. This line allows 20%~30% recycled PE (max 50%) to produce a smooth inner surface and slash raw material cost greatly.

Core Advantages

✅ Higher capacity: up to 50% faster output

✅ Stable quality: efficient cooling ensures high yield rate

✅ Cost saving: wide recycled material usage and low energy consumption

Ideal equipment to improve profitability amid booming infrastructure construction.
