Management of Modification

To meet new market conditions promptly and flexible, we established an extensive management of modification. To secure the flexibility towards our customers is our primary target. We activate the customer orders in “the last moment“, so we are able to react still on changes shortly before the delivery. This offers the customers a tremendous value for the serial production. 

For Traceability all applicable modifications will be registered in a database. The documentation begins with the first serial production of the product.
