Power Cord Manufacturing Process
Liandung combines decades of OEM experience with professional power cord manufacturing. From R&D to testing, we adhere to strict international safety standards to deliver the most reliable outsourcing solutions for our clients.
1
Raw Material PreparationThe process begins with procuring essential raw materials, including copper wire, PVC resin pellets, and other components required for manufacturing power cords and extension cables.

Metal and Plastic Housing
2
Conductor StrandingThe copper wires are drawn and twisted together to form the copper conductor of the power cord.

3
Core Insulation ExtrusionThe copper conductor passes through a PVC extrusion machine, which applies a layer of insulation to protect the wires and provide electrical insulation.

4
Core Twisting (Lay Length Adjustment)Insulated cores of different colors are twisted together to form a multi-core stranded wire used inside the power cord.

5
Outer Sheath ExtrusionAfter completing the multi-core stranded wire, an outer layer of PVC is extruded over it using an extrusion machine to protect the finished cable from external damage.
