Automotive Wire High Speed Extrusion Production Line 1500m/min
Components of the Cable Extrusion Process
Raw Material Preparation**: The process begins with the selection and preparation of raw materials. Common materials include copper for electrical conductivity and polymers like PVC (polyvinyl chloride), PE (polyethylene), or XLPE (cross-linked polyethylene) for insulation. These materials must be of high purity and specific formulations to meet the required standards.
Feeding System**: The prepared raw materials are fed into the extrusion machine’s hopper. The hopper controls the flow of material into the extruder, ensuring a consistent and continuous feed, which is critical for maintaining the quality of the extruded cable.
Extruder Machine**: The heart of the extrusion process is the extruder machine. This machine comprises several key parts:
* Screw: A rotating screw inside a heated barrel that pushes the material through.
* Heated Barrel: The barrel heats the material to its melting point, making it pliable enough for extrusion.
* Die: A specially designed tool that shapes the material as it is forced through. The die’s design determines the cable’s final cross-sectional shape.
Cooling System: Once the material exits the die, it is immediately cooled to solidify its shape. This is typically done using water baths or air cooling systems, depending on the material and desired properties of the finished cable.
Pulling and Winding: The extruded cable is then pulled through the cooling system by a capstan or take-up device, ensuring it maintains its shape and consistency. Finally, the cooled and solidified cable is wound onto reels or spools for storage and transportation.
The automated production line is specially used for the manufacturing of wires and cables, which can realize the continuous insulation coating of metal conductors (copper/aluminum). The winding and packaging can be matched with KPS cone-shaped reel fully automatic wire taking-up machine, double-head coiling machine, double-reel semi-automatic wire taking-up machine, etc.
