Other services
We implement the following additional services for you:
Combination layers
By combining PVD coating and anodic oxidation, we are able to create a variety of color effects with metallic feel (tactile properties) of an object. Furthermore, we offer electroplating-PVD combinations for the production of highly resistant coating systems. This gives us expertise that leaves hardly anything to be desired when it comes to surface finishing – and all from a single source.
Ultrasonic cleaning
Ultrasonic cleaning is a very effective method of removing surface contamination. This is a so-called power sound application.
Advantages are gentle pore-deep cleaning without scratching, brushing or scraping, easy and fast handling as well as short cleaning times of a few seconds to a few minutes.
Ultrasound can also be used to effectively clean surfaces with complicated geometry, such as recesses and crevices.
Mechanical processing
Depending on the material and the type of further treatment, the workpieces are processed with a wide variety of grinding wheels to remove coarse material, obtain a smooth surface, remove oxides or optimally prepare parts for polishing.
This is a fine machining process in which so-called roughness peaks of the surface structure are leveled by material removal and deformation. Polishing is mainly used to create a smooth surface in order to achieve a high gloss when coating later on. In addition, it is often applied to treat intermediate layers before chromium plating.
This surface treatment is mainly used to create textured surfaces on components made of steel, stainless steel, bronze or brass, for example. Brushing is also used for cleaning, descaling and derusting of workpieces. A wide range of brush types is available for the most diverse applications.
Blasting is a method of surface treatment in which the so-called abrasive is thrown or blasted onto the metal surface. Depending on the field of application, different blasting media with different grain sizes (e.g. corundum and glass beads) are used. Contaminants such as coatings, scale or rust can be effectively removed. So-called decorative blasting to create certain surface structures is another application.
Surface analysis
Our surface analysis laboratory is equipped with characterization devices necessary to ensure undisputed high quality of the produced coating on a daily basis. The qualified quality engineers with thorough understanding of coating physics constantly cooperate with the production department and this allows the fastest response to any coating problems.
Over the decades, our company has also developed professional cooperation with several other institutions and companies. Cultivating these relationships expands our understanding of characterization technologies and, in turn, the quality service offered by our company.
