In order to improve the quality of our input control of materials for gasket production, we have purchased a tensile testing machine.

Now we are able to:
  • Check the mechanical properties of purchased materials.
  • Verify the values stated on the supplier's materials sheets.
  • Check the dimensions, hardness and quality of the material surface.
  • Guarantee the customer's required parameters.
