Manifold services such as (complete) tool processing, polishing, jet blasting and coat removal complete the scope of services and performance. This allows us to guarantee optimally aligned treatment. The in-house logistics system supports the integrated surface engineering concept. In times of increasingly short deadlines, it provides for a mode of work organisation that is ideally integrated with customer processes.

Creating ideal preconditions

  • By means of polishing, the required surface roughness of the active tool surfaces is achieved without damaging the micro structure
  • An optimum polishing process creates the best conditions for a subsequent surface treatment

Saving costs through multiple use

  • Forming and hard-metal tools can be repeatedly used
  • No costs for manufacturing of completely new tools


Chemical coat removal:

Removal of coats on steel and hard-metal tools takes place by means of a chemical-thermal procedure which does not impact the base material. The surface quality is maintained and the polishing requirement reduced.


Mechanical coat removal:

In mechanical coat removal the coat is removed using an abrasive technique. This is accomplished within a short period of time with minor abrasion of the base material. The surface can be levelled
and restored for a new coating.
