Automotive Industry

Compared to other businesses the automotive industry requires a much larger variety of components made from different materials. 

Numerous castings, forgings, stampings or machined parts require a specific surface finish, or plastic components must be coated in our Rotamat coaters: Every single component is subject to clearly defined surface finish specifications.  The processing targets range from the deburring of engine blocks, the descaling of connecting rods, the edge radiusing of seat belt tongues, all the way to the polishing of high performance motor sports components. 

Especially for the automotive industry there are no guidelines for “the” most suitable solution.  With the experience of hundreds of successful applications our experts can quickly develop optimum surface finishing solutions for specific components and finishing demands.  They are always doing this with a clear focus on integrating the finishing equipment into the customer’s manufacturing operation and on cost efficiency.

Depending on the particular surface requirements either a mass finishing or shot blasting process may have to be utilized.

When it comes to descaling, de-flashing and surface homogenization of forgings and die-castings, mostly shot blasting is utilized. For example, for cylinder head covers, steering knuckles, pump housings or connecting rods.

Mass finishing is usually the preferred finishing method for nearly all assembled steel or light metal components like turned and milled work pieces for transmissions, chassis, bearings or clutch elements.

The Rotamat coater is utilized to create the perfect surface finish on mass produced small parts. Operating buttons and control elements must frequently have a decorative coating, while sealing and O-rings require mostly a functional coating, for example, a lubricant. Numerous Rotamat coaters are used for the application of a primer on parts that must be lined with rubber or metal.

The overall result: The components receive a targeted and repeatable surface finish that fully complies with the functional and optical specifications…long lasting and within tight tolerances.
