Quality certifcates and tests

All wires manufactured in our company are tracked through permanent quality controls from goods receipt to goods issue or for in-house processing. Our production facilities record and document various test parameters with integrated measurement equipment.

available systems among others
  • Rolling mills: dimensional checks
  • Compliance systems: profile and dimensional checks
  • Enamelling plants: voltage testings, surface inspections
  • Kapton insulation systems: voltage testings
  • Mica film insulation systems: Monitoring of overlapping and offset with camera

Apart from that workers check the quality of their own work every hour. The data recorded here are documented in the procedure documentation as well. In our test facility each batch of the wire is controlled according to inspection plans. The results are documented in inspection protocols. With every delivery the customer receives an acceptance test certificate 3.1 according to DIN EN 10204.
