GPT Automotive Wire Extrusion Line

GPT Automotive Wire Extrusion Line

GPT cable (General Purpose Thermoplastic) is an automotive low-voltage wire under the American standard (SAE J1128) system, widely used in the conventional circuit systems of American, Japanese, and domestic vehicle models.

The GPT automotive wire extrusion line is a specialized equipment designed specifically for producing automotive low-voltage cables that comply with SAE J1128 standards, suitable for wire harness manufacturing of American, Japanese, and new energy vehicle models.

Composition of Production Line

The GPT automotive wire extrusion line mainly includes the following core equipment:
Pay off Stand: Release copper conductors to maintain stable tension.
Preheating Unit: Heat the conductor to improve insulation adhesion.
Extruder: Melt PVC coat the conductor.
Cooling Tank: Segmented cooling and shaping insulation layer.
Haul off: Control the speed of the production line.
Take-up Reel: Automatic winding of finished wires.
Testing Equipment: Spark tester, laser diameter measuring system, etc.

Process Flow

Pay-off → Preheating → Extrusion coating → Cooling and shaping → Spark detection → Printing → Take-up.
