Surface Treatment and Silicone Coating of Metal Parts
In our production process, we place great emphasis on in-house surface finishing, as it has a decisive impact on the quality of our products. We use various methods to ensure that the surfaces of our workpieces meet the specified surface finish requirements.
One of the methods we use is sandblasting. In sandblasting, a high-pressure air jet with fine sand particles is directed at the workpieces. This process efficiently removes impurities, rust and other deposits, resulting in a clean and even surface. This is particularly important to improve the adhesion of coatings or joints.
In addition to sandblasting, we also use the Rotofinish process. The workpieces are placed in a rotating drum in which abrasive media such as balls or chips are used. While the drum rotates, the workpieces are gently ground and polished. This results in a uniform surface with improved surface quality and texture.
Finally, we use Trowal systems for surface treatment. In these special machines, the workpieces are cleaned and treated in a water bath with special chemical solutions. This process is particularly effective in removing oil residues and preparing the surface for subsequent processes such as coating or electroplating.
The combination of these methods ensures that the internal surfaces of our products meet the required quality standards and therefore plays an important role in the manufacture of high-quality products. We remain committed to constantly seeking improvements in our surface finishing processes in order to continuously increase customer satisfaction and the quality of our products.
Silicon Coating of Metal Parts
The silicone application process is an additional step in our manufacturing process, for which we use a state-of-the-art volumetric dispensing system. This system was specifically designed for industrial bonding, sealing, and potting applications and provides us with a high degree of accuracy and repeatability.
At the heart of this system is a high-precision 3-axis gantry robot that ensures repeatable silicone application. One of the main applications of this dispensing system is applying silicone beads to metal parts. This process requires the highest precision, as the quality of the bonding and sealing depends largely on the accurate dispensing and distribution of the silicone. Particularly noteworthy is the versatility of this system, as it can process a wide range of materials—from low- to high-viscosity, unfilled and abrasive to heat-activated materials. This flexibility enables us to manufacture a wide variety of products and meet a diverse range of customer requirements.
After the silicone beads have been applied, the finished products must cure to ensure a firm bond. This step completes the siliconization process and ensures the desired results in terms of bonding and sealing. Siliconizing is used in the food industry, the automotive industry, medical technology, the construction industry and many other sectors.
EXTERNAL SURFACE TREATMENT
To ensure that our products aren’t limited to a monotonous “metallic gray,” we offer a wide range of surface finishing options tailored to our customers’ individual preferences. We place great importance on ensuring that the surfaces of our products are not only visually appealing but also functional and durable. For this reason, we work closely with external specialty firms that are certified to DIN EN ISO 9001/16949 and meet high quality standards.
Our customers can choose from a wide range of surface finishes to tailor their products perfectly to their needs. With these diverse options, our customers can be confident that their products are designed to meet high quality standards – not only in terms of functionality but also in terms of appearance. We are proud to collaborate with our certified partner companies to offer our customers suitable surface treatments.
