Quality management

This is the reason why you want to co-operate with business partners who can offer you a high level of consistent, guaranteed quality, both with regard to products and processes! 
As one of the first companies in its industry, WLT has had its quality management system continuously certified according to DIN EN ISO 9002:1994 since 1995. The current state of certification, now corresponds to the latest version of the standard, DIN EN ISO 9001:2015. 

Furthermore, WLT has made another step in order to reach its aims with respect to customer orientation and process optimisation, exceeding standard requirements by far. A dedicated, substantial project was originated for these purposes. 
The result is a management tool integrating and continuously optimising each corporate division, so that WLT customers can rely on their partner also in the future.
