host system

Screw design: Adopting single screw or twin screw configuration (screw diameter 50-75mm), optimizing the groove depth and compression ratio for different materials. For example, PVC processing commonly uses conical twin-screw, while PE/PP is suitable for parallel twin-screw.

Temperature control module: zone heating (barrel divided into 4-6 sections) combined with air cooling system, temperature control accuracy reaches ± 1 ℃, avoiding material degradation. For example, the processing temperature range for PVC is 160-190 ℃, while for PE it is 180-220 ℃.

Drive system: equipped with variable frequency motor or servo motor, with extrusion speed fluctuation rate ≤ 1%, suitable for high-speed extrusion requirements (such as corrugated pipe production line speed up to 30m/min).

Mold and runner optimization

Multi cavity mold technology: support efficient production modes such as "the first mock examination with four outlets", reduce equipment investment costs, and apply to the mass manufacturing of φ 16-200mm wire pipes and water supply pipes.

Composite co extrusion head: can stack different materials (such as PPR+fiberglass reinforcement layer) or colors to meet the needs of functional pipes.

Cooling and shaping system

Vacuum Spray Box: Made of SUS304 stainless steel material, with a vacuum degree of -0.08~-0.1MPa, and equipped with multi-stage water cooling modules to accurately control the roundness of the pipes (tolerance ± 0.1mm).

Three dimensional adjustment device: supports height and horizontal fine-tuning, suitable for the shaping requirements of complex shaped pipes.

Traction and cutting system

Multi mode tractor: Wheel traction is suitable for flexible hoses, track traction (traction force up to 8kN) is suitable for hard pipes, and speed synchronization error is ≤ 0.1%.

Intelligent cutting device: Circular saw blade cutting machine (accuracy ± 0.5mm) is used for small-diameter pipes, and planetary cutting machine (accuracy ± 1mm) is suitable for large-diameter pipes.
