Sintered molded parts

Sintering is a process that has become established for large series of machine components due to its tight dimensional tolerances, smooth surfaces and high cost-effectiveness. Plain bearings and molded parts in particular are made of sintered metals. We specialize in providing solutions to related requests.

Sintered parts are pressed into a precisely defined shape under high pressure. At the beginning of the sintering process, mixtures of metal powder are pressed using a complex tool. The resulting pressed part is sintered at a temperature of up to 1350°C. In order to achieve the highest possible precision, the finished part is calibrated and - if necessary - heat-treated, surface-coated, mechanically reworked, joined or assembled. Sintered parts are manufactured ready for installation in most areas of industrial production and are impregnated with individual lubricants and hardened or galvanically finished.

Compared to other manufacturing processes, sintering technology enables maximum utilization of the material with the lowest possible energy consumption. Thanks to our diverse experience, we can guarantee our customers customized and cost-effective solutions.

Key advantages

The advantages of powder metallurgical products are obvious.

Sintered components have the highest dimensional accuracy, even with complex geometries, and are characterized by the reproducibility of large quantities. Together with you, we define customized material properties for your components and design them to suit the application and sintering process.

Cost savings

Our customers benefit from the technological advantages, our decades of experience and our extensive know-how in sintering technology. Choosing sintered products brings you very specific advantages:

– ready-to-install components at low unit costs
– Material yield of almost 100%
– Components in all finishing levels and material qualities

Material classes, sintered materials

The properties and designations of the materials for sintered parts are standardized in material data sheets according to DIN 30910. The sintered materials are divided into different classes, which are identified by letters; the criterion for classification is the porosity, expressed as the ratio of material to total volume of the sintered part. Due to its properties, each material class is particularly suitable for certain areas of application.
