Features

1. High plastic extrusion capacity
The design of screw can strengthen cutting and avoid decomposing by overheat. Fast melting of plastic can be realized in order to extrude plastic at high speed.

2. High performance cooling system
The inner water-cooling and fan-cooling of high-precision copper wing-piece to guarantee heating balance and precise temperature control.

3. Special output flow path designed for melted plastic guarantees high quality of extrusion.
4. Power-saving. This cable sheath extrusion line consumes power of 0.18º/kg, saving more than 78% of power compared with common extruder (0.32º/kg).
5. High performance electric control system and temperature control instrument. Precision is ±2º. Outside diameter tolerance of jacket is ±0.2 mm.

5. Material loading and drying system
Material loading: SAL-800G
Drying: SHD-400

6. Cooling trough
The cooling trough of this cable sheath extrusion line is made of 2mm stainless steel. It consists of heating trough and fixed trough, with 4-meter movable trough and the moving distance is 1m. The inner size of cooling trough (width × depth) is 360 × 400mm.

7. Compression air dryer

8. Electric control system
This cable sheath extrusion line uses PLC and touch screen to control. Each control cabinet controls the electric parts of the extruder unit and the caterpillar. The cabinet controls the temperature, line speed, screw rotational speed, extruder current, meter counter, etc. It will send alarm when it’s overloaded. When change the speed of this cable sheath extrusion machine, the PLC will set corresponding parameter automatically. In addition, three emergency stop switches are designed on the whole line (caterpillar, extruder and take-up stand).
