Types of electrical cable extrusion machines

Electrical cable extrusion machines come in various types to meet different requirements when manufacturing cables. Below are some of the commonly used cable extrusion machines.

• Single-screw extruder

  The single-screw extruder is the most common component of electrical cable extrusion lines. It uses a helical screw located in a barrel to push and melt raw materials. Generally, the helical screw has three zones: a feed zone, a melting zone, and a pumping/dispersion zone. The melting in different zones happens because varying temperatures are set. As the helical screw rotates, it conveys the material forward until it reaches the end of the barrel, where the material takes shape or is cut into pellets. Single screw cables can be economical options for producers.

• Multiple screw extruder

  Like single-screw extruders, multi-screw extruders melt raw materials using screws. However, they have more than one screw, usually two to twelve. This leads to better material processing and higher output. The two main types of multi-screw extruders are twin-screw extruders and other multi-screw patterns. Materials can be mixed and melted homogeneously thanks to the unique design of the screws. Multi-screw extruders occupy a small floor space, but they are more costly than single-screw variants.

• Direct crosshead

  A direct crosshead is a device that puts the insulation layer onto the conductor of a wire in a straight manner. With shorter cable feeds and less scrap, this spray-on method is more efficient than typical extrusion methods. The absence of cable tails from direct crossheads also reduces expenses associated product manufacture. Direct crossheads are simple to use and can insulate wires made of various materials, including PVC, PE, Kynar, Santoprene, FEP, and PVDF.

• Pipe flipper

  The extrusion device known as a pipe flipper is employed to flip cables in order to make straight cuts. Pipe flippers are also known as pipe turners. They are essential tools for cable extrusion lines since they facilitate the cutting of cables and wires in a straight manner. A cable cutter with a flying saw in the stand can make straight cuts while the cable or wire is flipped in an upright position. For the most effective production, flip machines like this one are employed in conjunction with saws that instantly cut as the cable is flipped, doing tasks like cutting and striping simultaneously.

Specification and Maintenance

The specifications of cable extrusion machines can vary depending on the model, make, and production capabilities.

• Production Capacity: The production capacity is often measured in kilograms per hour (kg/h) or pounds per hour (lbs/h). It indicates the amount of cable material the machine can process and produce in a given timeframe. For example, a cable extrusion machine with a production capacity of 100 kg/h can produce up to 100 kilograms of cable per hour.
• Cable Diameter Range: The cable extrusion machine can produce cables of different diameters. The diameter of the cable is typically measured in millimeters (mm) or inches. For example, a cable extrusion machine may have a diameter range of 1 mm to 10 mm, indicating that it can produce cables with diameters within that range.
• Power: The extrusion machine's motor drives the extrusion process. The machine's motor power is measured in kilowatts (kW) or horsepower (hp). Higher motor power may be necessary for handling and processing more complex cable materials.
