• Sand blasting

  The sandblasting is one of the processes of surface treatment and is mainly used for removing rust, soiling, colour residues and other impurities. In the method, a blasting agent is thrown at high speed onto the surface to be treated. Sandblasting enjoys great popularity in the metalworking industry and in construction. On the one hand, the method can be used for efficient removal of impurities and for the preparation of surfaces, but on the other hand also serves for the production of optical effects such as, for example, the matting of glass or stone surfaces.

• Sheet metal processing

  The sheet metalworking includes various for manufacturing custom sheet metal products. The starting material of the sheet metal processing is a sheet metal sheet or coarse sheet metal, which is brought into the desired shape and the desired design by cutting, forming, joining and finishing in various processing steps. Due to the multiplicity of different functions and applications, different methods for sheet metal processing are used in the metal processing industry. The most common methods include welding, cutting, bending, punching, shaping, rolling and joining.

• Spot welding

  The spot welding is also referred to as resistance spot welding and is one of the welding methods without using protective gas. The method is based on the punctual heating and liquefaction of two workpieces pressed on one another by applying a strong voltage. Compared to other welding processes, spot welding is characterized by good productivity, a high degree of automation and a low material distortion. For this reason, the joining method is used primarily in bodywork and vehicle construction, in sheet metal processing and in the electrical industry.

• Steel profiles

  Steel profiles are steel components which have the same cross-section over their entire length. Steel profiles are usually produced by rolling, drawing or pressing and are used as construction steel or for the production of rails, ladders or struts. When using steel profiles, it is crucial to tune the decisive material or component parameters to the application. It should be ensured that the static moment, the moment of resistance and the moment of inertia of the surface correspond to the load requirements of the respective application.

• Supplier management

  The term supplier management describes the systematic management of the relationship between a company and its suppliers. Supplier management aims to optimise its own value chain economically and technically through a transparent comparison of suppliers. Supplier management has become increasingly important in recent years, as the share of external value added in German companies has steadily increased. In industry, the share of external output is now around 70%, which means that the value added to external enterprises is shifted. This shift leads to the fact that the cost-effectiveness of procurement processes offers an increasing potential for improvement.

• Surface hardening

  The use hardness refers to a thermochemical process in which the mechanical properties of the edge layer of metallic components are improved in a targeted manner. In this case, the surface is first carbonized, then hardened and then let on. The use hardening is carried out in the hardening process and allows the user to impart a significantly higher surface hardness to the edge layer of the workpiece. Use-hardened components are distinguished by a correspondingly high wear resistance with increased bending fatigue strength and are thus particularly predestined for use in transmission technology.
