IQC - Temperature resistance test of copper wire

IQC is the first quality control barrier before production. Transformers used in different fields have different requirements of Temperature resistance for copper wires. Our IQC team will use oven to perform Temperature resistance test of the copper wire in strict accordance with the requirements provided by our engineer, recording the test data and results. 

Eliminate unqualified raw materials to ensure the quality of the subsequent production process or final products and save production costs.


In Liqin, IQC is one of the most important team belongs to Quality Department,who plays a very important role during the whole production progress.


For different raw materials, we have corresponding testing items and equipment to assist our IQC to do the tests.


  • Raw material: Copper wire

  • Test item: Temperature resistance test

  • Test equipment: Oven
