To provide customers with high quality and reliable electrical wire and cable, ZMS is available in strict quality tests in all product production processes.
raw material test
The testers in our quality testing department will carry out strict inspection on purchased aluminum rods and aluminum clad steel., and after they have been qualified, they will issue a quality test record and place them in the warehouse for later use; on the contrary, materials will be tagged as unqualified and retested, if you are not yet qualified, will be sent back.
Production process test
Initial Product Inspection: when cable production work starts, the production of different cables is required or when there is an adjustment of production techniques, there will be inspection work by operators and after all these processes have been tested, testers will complete an initial product inspection record based on the relevant test procedures, while if the initial inspection is tested without qualification, there will be a rework or remanufacture until they are qualified, later, products can be produced in large quantities after confirmed and signed by testers. After the products are completed in each process, They will be inspected in the inspection and waiting area for testing and can be placed in the next process after being inspected and qualified..
Finished product testing
Finished wire and cable products will be tested on appearance by packing staff and sent to quality inspection department by special inspectors for batch sample inspection based on complete and qualified special inspection record..
