Plant location EITEC Bochum

EITEC has been dealing with metallic and non-metallic tools and components using the PVD process since 1991.

Since July 1st, 2018 we have been trading under the name WOLF.

WOLF provides its own research and development to continuously update the service offering for the European region. WOLF is independent in plant construction, offers system solutions for the chemical-free stripping of PVD carbon layers and the machine-readable laser coding of shaft tools to increase profitability.

The WOLF-Team is not only committed to quality according to ISO 9001:2015, but is also constantly looking for environmentally friendly technical solutions and implements them in-house. For example heat recovery and waste avoidance through vacuum distillation.

PVD coatings are nowadays as a well-known technology introduced with regard to wear protection, friction reduction and biocompatibility.

PVD layers are produced in environmentally friendly vacuum processes under plasma conditions and are preferably vapor-deposited on metallic and ceramic surfaces.

The low process temperatures allow coating at temperatures that are below the tempering temperature of steels and thus rule out a structural change (see CVD process).

PVD layers are usually created with a layer thickness of 2-5 µm; the accuracy is given as +/- 1 µm.

PVD layers are usually the last step in the manufacturing of a finished tool or component – unless the coated surface is smoothed by micro-blasting or polishing.

Nowadays, PVD layers are very often applied in combination with surface hardening (HARD EDGE) to ensure sufficient support hardness for the PVD layer.

The variety of layers has increased significantly in recent years due to the demands placed on the performance / lifetime of tools and components.

The technical requirements grow with the performance of the machines, with the commercial requirements for covering the manufacturing costs and the legal requirements for the environment (hard chrome plating is prohibited).

In addition to our coating service, another focus is on innovative in-house developments in plant construction.

 

  • PVD plant construction
  • Toolmark device
  • Device construction
  • Cleaning systems

Trust in our quality certification

Certification

We have been ISO 9001:2015 certified for over 20 years.


Environmental protection

The vacuum processes according to the PVD process run without pollutant-containing emissions! The resulting process heat in cleaning and coating will be used for the heating of the company buildings!
The alkaline baths used in the cleaning process are 100% cleaned by vacuum distillation; the residual sludge, reduced to <5%, is disposed of.


Our certification for the medical and food sector

The use of our DLC layers in medicine and food is harmless and has been confirmed by the Fresenius Institute.
