Surface Finishing

With our state-of-the-art surface technologies, we offer both functional and decorative coatings. These techniques not only improve the aesthetic aspects but also the resistance and longevity of the components against environmental influences and mechanical stress.

The functional requirements include corrosion resistance, surface hardness, wear resistance, sliding properties, as well as thermal and electrical conductivity. At the same time, certain external properties such as color, roughness, gloss, and adhesion are required to ensure that the component can optimally fulfill its final purpose.

Anodizing

Anodizing is a surface treatment applied to non-ferrous materials like aluminum for decoration and to improve functional properties. It is an electrochemical process that makes the metal durable and resistant to corrosion/scratches.

Electroplating

Electroplating offers a cost-effective way to enhance the functionality and appearance of aluminum die-cast products. It enables the formation of a thin metal layer on the surface of products, leading to increased durability and corrosion resistance.

Chroming

Chroming provides enhanced durability, corrosion resistance, and an aesthetic appearance for aluminum die-cast products. Through hard chroming, hardness and chemical resistance are also increased, which enhances functionality in

Powder Coating

Powder coating is an efficient method of color coating, where the finest solid particles based on polyester and epoxy resins are applied to an electrically conductive workpiece and baked at temperatures of up to 220 °C. This environmentally friendly coating option offers a wide range of colors and shades, as well as excellent corrosion protection.

Polishing

Polishing significantly enhances the gloss and aesthetics of aluminum die-cast products. By eliminating defects and smoothing the surface, a mirror-like finish is achieved. The process includes steps such as roughing, polishing, brightening, and protection, allowing for diverse surface design. Depending on the material, automated or manual polishing can be used to achieve optimal results.

Vibratory Finishing (Trowalizing)

Vibratory finishing, also known as trowalizing, is a process for the targeted finishing of surfaces of cast blanks for their later use. In this process, the blanks are placed in a vibrating container with special abrasives to remove material. The movement of the abrasive media results in a smoothing effect, creating the desired surface finish. The variety of abrasives used allows for targeted adjustment of the outcome. Vibratory finishing or trowalizing is particularly suitable for small workpieces.

Sandblasting

In sandblasting, we prepare the surface of our die-cast blanks for the final treatment. Here, blasting media is directed at high speed against the workpiece surface to achieve maximum homogeneity, optimal adhesion, and texture. This pretreatment ensures that the aluminum cast part is ideally prepared for the final surface treatment, such as powder coating, which serves both decorative and corrosion protection purposes.
