Before and after coating
Together with our customers, we determine the best possible solutions for each individual component.
In addition to the optimal coating, the most important desired properties (e.g. corrosion protection, tribological behaviour, electrical conductivity, etc.) are explained in a practical way.
In addition, we also provide information on the most economical processes and logistical concepts.
Corporate customers, universities, technical colleges and bachelor’s/master’s degrees take part in our surface coatings training courses.
Developers and designers in particular appreciate the fact that, in addition to theory, they are also taught our practical knowledge.
The participants receive certificates for their participation.
Directly at the customer’s site, our field service determines the individual requirements that are necessary for the successful realization of the project.
Furthermore, our mobile measuring devices can also be used to inspect already coated customer parts.
If a radiological examination is required, our certified radiation protection officers are also available.
Automated setting and riveting
Bolts, rivets, clips, pins and blind rivet nuts can be fed from our automated systems and then set.
Press-fitting of rubber mountings
We are happy to carry out various press-in tasks for you, such as defined press-in of rubber bearings, ball bearings, chassis bearings, spring link bearings, ball sleeve joints and ball bushings.
Application of sealants
Sealants fulfil various functions: For example, sealants can be used to create a barrier to retain liquids, gases, air or other substances, or a long-term elastic connection can be created between different elements. Talk to our experts to find the right sealant for your application /strong>.
We offer all common screw locks and screw pre-coatings according to DIN standards and manufacturer specifications – in addition, special solutions for special applications can also be realized.
Avoiding hydrogen brittle-fracture. In the process of zinc electroplating hydrogen is formed and diffuses in the metal structure. In the special material structure of high strength steels, hydrogen passes through the metal structure and leads to embrittlement of the material. Result is the fatigue and rupture of the part. According to the technical specifications, we conduct precisely specified heat treatments (tempering), to expulse the hydrogen from the material. This process must be conducted latest 4 hours after coating. Dainty documentation of this process is indispensable for the quality management.
Oiling of parts for short-term corrosion protection to preserve the non-coated parts in the selective coating process in the time of transporting and storage until final assembling. Combined with zinc-phosphating, corrosion protection up to 96 hours in the salt spray test are feasible.
Upon customer requirements we take over assembling tasks after surface treatment. Particularly in the case that assembling processes need to be operated after the surface treatment, the result is going to be a reduction of the overall cacle time and reduced effort for transport. The individual components do not have to be transported to our customer for assembling but will be finished and transported by us to the end customer. The scope ranges from simple mounting accessories to the complete overtake of fully automated assembly lines in series production.
Preparation for the optimal surface coating. Metal parts could be magnetised in the production process. This magnetism disrupts the coating process and lowers the quality of the surface coating. Upon your demand, we demagnetise your parts in-house to reduce your efforts and ensure a high quality of the surface coating.
Re-work of uncoated areas. Residues on uncoated areas caused in the process of selective coating must be carefully removed and cleaned. Particularly in the case of bearing seating and flanges, high precision is key to ensure the specified tolerances. This is vital to ensure the function of the part.
For the adherence of predefined coefficients of friction. The defined coefficient of friction is monitored and documented with state-of-the-art test equipment. You can be sure that we fully meet your requirements and use your inspection reports for your documentation. Particularly in the case of safety-related components you should not leave anything to chance.
Detailed exams of the layers within the process development. In terms of process development, every detail counts. Processes can be improved and required characteristics of the layers can be met only with deep knowledge of layer compositions. With state-of-the-art analysis tools, we support your development process, to achieve the required characteristics of your products quick and reliable.
Besides the corrosion protection, it is also critical to meet the required layer thickness or coat thickness distribution on the part. We check the layer thickness during the series production with ultramodern magnetic induction layer thickness measurement devices or X-ray fluorescence analyses and provide our customers a document to indicate the norm conforming layer thickness.
Tensile & compression tests
The tensile test is used to determine the strength and deformation characteristics of materials under uniaxial, uniformly distributed loads over the cross-section in accordance with DIN EN ISO 6892-1. The advantage of the tensile test is that even ductile materials can be tested to complete fracture.
In a bending test, a specimen is plastically deformed until a certain bending angle is reached and the specific characteristic data recorded. With the bending test we determine the deformability and potential irregularities on the surface.
Main feature of the applied functional layers is corrosion protection. We thoroughly check our coatings with state-of-the-art test equipment (salt spray chamber, Kesternich Test, thermal shock oven etc.). The evidence of the corrosion resistance is carried out according to common specifications, e.g. salt spray test according to DIN EN ISO 9227.
Qualitative and quantitative description of the metallurgical consistency by microscopic methods.Coatings are in constant interaction to the material manipulated. Only the detailed knowledge of those interactions and the necessary set-up of coating processes can reliably eliminate undesired sideeffects. Involving us already in early project phases of our customers to select appropriate material and development suitable for coating enables to reduce negative and costly effects on the coating.
Hardness measurement after Vickers to evaluate and document the hardness in the state as delivered and hardness after thermal curing. Layer systems or selective coated parts can be measured. The part itself or, if not feasible, the grinding of the part can be measured as well. Hardness measurement during production is possible. All basis coating materials can be measured.
Upon your request, our own truck fleet enables quick and short-term actions to pick up your parts for surface treatment or return the finished parts.
With a preordained schedule and strictly our own drivers, we know the individual circumstances of our customers rather well and can adapt subsequently. Therefore, our customers have a maximum of planning reliability. Should you get in a difficult schedule situation due to unforeseen events, we will take action after a special agreement and in line with our production to support you in short notice by dispatching your order in our production planning. Loading our trucks with finished parts also outside the usual time frames for freight forwarders, we can contribute that you can get back to a normal delivery mode as soon as possible.

Logistics VDA standard
End-to-end solution starting with picking up of the parts to the shipment of finished parts to the end customer.
Not only the traditional transport from A to B but also the complete paperwork, EDI-setup, monitoring and management of call-offs, management of empties etc. is part of the end-to-end solution. Delivery on behalf of our customers is reducing the overall cycle time and effort for transport.
100% check for missing parts, grade purity and shape deviation, packing in the correct quantity.
Components are automatically sorted and checked for errors in an additional operation. By means of optical measuring procedures, the most diverse characteristics are recorded. If components lie outside the required tolerance ranges, they are sorted out – furthermore, mixing with foreign parts can be excluded by the inspection. Holder tests with various sorting systems in order to be able to map a wide range of workpiece geometries.
Packaging according to lot sizes
100% check for missing parts, purity of grade and shape deviation, packaging in accordance with number of pieces.
