The service-lives and surface properties of tools in many cases determine the costs and productivity of manufacturing operations. Our coatings offer the benefits both of minimizing setting-up and downtimes and of reducing tool costs. The unique advantages of Surcoatec technology open up numerous applications in which coating processes could not previously be used. Many of these demand high hardnesses, in addition to the coating of extremely complex surfaces.
Example: Micro drills
The assignment
Development of a coating which will eliminate clogging and thus improve drilling quality.
Objective
- Assurance of constant drilled-hole quality
- Longer service-lives
- Reduction of materials costs (replacement of worn tools)
Result
Drilling tests confirmed an improvement in service-lives by a factor of 12, with a constant high drilled-hole quality. The processes necessary for high-volume production are currently being developed in cooperation with this customer.

Example: Deep-drawing die
The assignment
Development of a coating to protect this forming tool against cold welding with the product material.
Objective
- Improved product quality thanks to less cleaning
- Lower consumption of lubricants
- Wear protection
- Reduction of friction
- Longer service-lives
Result
- The amount of cleaning necessary was reduced
- Servicing intervals, and thus downtimes, have been cut, thanks to improved friction and wear properties
- Fewer replacement tools are now needed, thus also reducing costs

Example: Injection moulding of plastics
The assignment
Development of a coating with a high hardness and optimum sliding behaviour which can be homogeneously applied in the mould runners despite the complex geometry of the mould.
Objective
- Protection against abrasive surface wear
- Improvement of product quality via optimization of flow
- Minimization of cleaning needs
Result
The mould runners were homogeneously coated. Mould service-lives have been significantly lengthened thanks to the increased surface hardness and the coating's non-stick properties.
