The Production Process of Electrical Power Cord and Extension Cord

1.Raw Materials: 

 The first step involves procuring the necessary raw materials such as copper wire, PVC plastic, and other components required for manufacturing the power cords and extension cords.

2.Wire Stranding: 

The copper wire is stranded together to form a bundle that will become the core of the power cord.

3.Core Wire Extrusion: 

The core wire bundle is then passed through an extruder that coats it with PVC plastic insulation to protect the wire and provide electrical insulation.

4.Core Wire Cabling: 

The insulated core wire is then twisted together to form a cable that will be used for the power cord.

5.Jacket Wire Extrusion: 

The jacket wire is then extruded with PVC plastic insulation that will protect the cable from external damage.

6.Automated Cutting and Terminal Crimping: 

The cables are cut to specific lengths and fitted with plugs and sockets using an automated machine.

7.Injection Molding:

The plugs and sockets are then molded into the plastic casing that will form the connectors for the power cord.

8.High Voltage Testing: 

The power cords are then subjected to high voltage testing to ensure they meet safety standards and can handle the required electrical load.


The finished power cords are then packaged and labeled according to their specifications.

10.Finished Product: 

The final step is to check the quality of the finished product before shipping it to customers.
