PU (Polyurethane) Precision Tube Extrusion Line

Description:

PU(polyurethane) tube features wonderful resistance performance against high pressure, vibration, corrosion, bending and weather, in addition, with the properties of convenient and flexible, this kind of tube is widely applied to air-pressure tube, pneumatic components, liquid conveying pipe and protection tube etc.

The particularity of PU tube application requires extrusion equipment to have the basic characteristics of “precise size control and high efficiency”.

Equipment Features

- PU Screw optimized by Japanese technological processing, can perfectly adapt to the PU material which is with high thermal sensitivity, flowability and melting viscosity, thus ensure even plasticization and high output efficiency;
- Core rods and die are made of Sweden “ASSAB” S136 die steel, precision grinding, which ensures the inner flow surface glossiness and anti-corrosion. Structure of mold adopts “high pressure volumetric type”, which is initiated by our company, can provide stable and high-speed extrusion for the tube material with tiny fluctuation;
- High precision processed melt pump with moving device, flexible moving. Front and back installed with melt pressure sensor _ Italy “GEFRAN” Brand, front melt pressure closed-loop feedback control system _ Italy “GEFRAN” instrument. Offer high stable output and automatic extrusion fluctuation adjusting;
- With the new “automatic accurate control of vacuum” technology: vacuum and water system controlled separately. In this way, we can coordinate the multilevel water balance control system with vacuum system, ensures stable vacuum degree, cooling water level and water flowing.
- BETA LaserMike measuring system, forming closed-loop feedback control, eliminating diameter deviation on-line;
- Puller equipped with multilayer wear-resisting synchronous belt, without sliding phenomenon. High level precision roller drive traction, YASKAWA Servo driving system or ABB AC driving system, realize extremely stable pulling.
- Special designed Winding machine with tension induction regulator, apply to soft pipes, keep winding under natural relaxation state, when tension condition change, the fluctuation within manageable scope, avoid tube over drew by too fast winding speed and too slow speed of winding.
