In order to guarantee our customers complete processing, Rieger also offers small assembly work. These range from the assembly of the finished product on racks which are needed in the production to the assembly of modules which goes to the end customer.
A large number of the workpieces that pass through the finishing process at Rieger are used in areas with high temperatures. To ensure in advance that the coating will last under these conditions, it is possible to carry out a temperature test. In this test, your workpieces are placed in an oven that can reach a heat of 400°C. The temperature and the time period are variable according to your needs. This test shows how the coating reacts to and withstands high temperatures. In addition, tempering serves to reduce hydrogen embrittlement, which can be caused by hydrogen in the material. Furthermore, tempering increases the hardness of the electroless nickel layer.
This area at Rieger deals with the preparation of materials. Mechanical preparation primarily means polishing, grinding and brushing in our in-house polishing workshop. These processes remove holes and so-called bumps on the still unprocessed surface of the workpieces. The advantage is a more uniform and smoother surface after or for the different surface treatments, such as chrome or nickel. Mechanical preparation can also be used as an intermediate step. This is often the case when the workpieces are of a very decorative nature. For example, the material is polished again after the copper in chrome plating to achieve a smooth, uniform surface.
At Rieger, customers have the advantage of getting preparatory work and surface finishing from a single source. This saves time and money and simplifies the process for our customers.
