SJ90/25 Flat Wire Extruding Machines.

1.Use:

This unit is suitable for coating the wire and cable with thermoplastic cable materials such as polyvinyl chloride, polyethylene, PE, XLPE, low-smoke and halogen-free by hot extrusion.

Flat cable/Ribbon cable extruder production line
1. Adopt custom head
2. Inveter control
3. Automatically monitor and adjust wire width
Application:
This extrusion line is applied to producing UL2468, 2651, 2678 and other computer flexible flat cables.
Characteristics:
This extrusion line adopts non-adjustable crosshead and special accumulator for flexible flat cable. The inverter control solves the problem of uneven thickness and wire tension, and prevents the copper wire from retreating after being cut. The equipped outside diameter controller helps monitor and adjust the outside diameter of the cable.
