Woundcore Quality Testing Process

Rigid quality control of all material is maintained from the time of their arrival in the stores to their issuance for production in our test laboratories, which are equipped with sophisticated testing instruments for electrical and mechanical properties.

 

 

"The sole guarantee of endurance and reliability is Quality". At VSPL this philosophy is implemented through stringent quality control measures that ensure strict compliance with specified standards. Quality control checks are carried out very strictly to ensure that only quality products reach our customers. Quality is monitored right from inspection of correct raw material to final stages when the products are thoroughly tested for:

Dimensional Testing accuracy.

  • Test on insulation coating to determine insulation resistance.
  • Iron loss tests.
  • Silicon percentage tests.
  • Laminating factor tests.
