Dimensionally stable coating – precision despite protective coating
The application of protective coatings inevitably leads to an increase in component size. In order to maintain precise tolerances, the increase is either neutralized by targeted chemical removal or already taken into account during mechanical processing. Thanks to dimensionally accurate coating, the dimensions of the components remain reliably within the predefined tolerance ranges.
Hard anodising – for maximum durability
Hard anodising, also known as hard anodising, enables the creation of extremely resistant surfaces on aluminium components. The use of high currents and temperatures close to freezing point results in a surface hardness of up to 550 HV (Vickers hardness). This coating increases abrasion resistance and significantly extends the service life of the components.
Ematalising – Minimal friction for precise applications
The Ematal process is particularly suitable for applications where friction must be reduced, whether through mechanical contact (e.g. plain bearings) or through flowing media (e.g. valve housings and nozzles for gases or liquids). In pneumatics and hydraulics in particular, Ematal ensures optimum performance with minimum wear.
Oversized anodising – for XXL aluminium components
BWB Surface Technology offers anodising of particularly large aluminium components. With a weight of up to 2 tons, a length of 22 meters and a height and width of 2.2 x 1.3 meters, even oversized components are coated efficiently and precisely.
