PU (Polyurethane) Precision Tube Extrusion Line
Product Overview
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.
Machine Components
Core rods and die are made of S136 die steel, precision grinding, which ensures the inner flow surface glossiness and anti-corrosion. The mold uses a high-pressure volumetric structure that provides stable, high-speed extrusion with minimal fluctuation;
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.
Puller equipped with multilayer wear-resisting synchronous belt, without sliding phenomenon. High level precision roller drive traction, servo driving system or AC driving system, realize extremely stable pulling.
Advantages & Features
PU Screwoptimized 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;
High precision processed meltpump with moving device, flexible moving. Front and rear industrial melt-pressure sensors provide closed-loop pressure feedback control. Offer high stable output and automatic extrusion fluctuation adjusting;
High performance online laser diameter measurement system, forming closed-loop feedback control, eliminating diameter deviation on-line;
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.
