The finishing of contact parts is crucially important to the end use. Whether a surface is to have the best possible resistance or good conducting properties depends on the field of use. The post-processing is of crucial importance to ensure that a coating layer can be applied as evenly and with as good an adhesion as possible. It guarantees an ideally prepared surface. These essential processes include vibratory finishing and rounding off edges, which are done using vibration machines and automated vibratory tumblers. The degreasing of all manufactured parts is done using the latest fully automated systems. For a thermal post-processing, various types of continuous annealing furnaces are used. In addition to this, a wide range of different parts can be subjected to a 100% test and inspection where required. The latest generation of test machines can measure and sort mass-produced parts in any desired position.
