Safety via production culture:

ZWT was first certified to DIN EN ISO 9002 in 1999, and then in 2004 to the new norm DIN EN ISO 9001:2015. Successful renewal occurs on a continuous basis.

Alongside the factual basis of certification we also invest continuously in securing and maintaining our production culture:

  • regular training and further education of all employees
  • comprehensive quality department
  • comprehensive production documentation
  • repeatable, permanently monitored production processes
  • regular in-house quality assurance audits
  • process of continuous improvement
