FROM THE FIRST DRAWING TO READY-TO-INSTALL DELIVERY

Design, tool making & machining – all under one roof

Ready-to-install sintered parts are not created in the sintering furnace alone. The path from customer requirement to finished component runs through a process chain that begins with sinter-friendly design, continues through in-house tool making and the sintering process, and ends with complete finish machining. Schunk Sinter Metals masters and takes responsibility for this entire chain – from a single source, at one site, with one point of contact.

Construction

Sinter-friendly design – solving problems before they arise

The quality of a sintered part is largely determined during the design phase. Geometries that are not designed to be sinter-friendly create problems in the pressing tool, in the sintering furnace, and in the dimensional accuracy of the final product. That's why Schunk Sinter Metals gets involved in component development as early as possible – ideally right from the first idea.

Our designers advise you on sinter-friendly component design: wall thickness distribution, draft angles, tolerance design, and the integration of functional surfaces directly into the pressing process. We use modern CAD systems and FEM analysis for component optimization. 3D data exchange with third-party systems and CAD-CAM connectivity with our tool making and production are standard practice.

Tool making

In-house tool making – precision for complex MIM components

The injection mold is the central element in the MIM process. It defines the component geometry, influences surface quality, dimensional accuracy, and process reliability, and thereby lays the foundation for stable series production. Schunk Sinter Metals has its own tool making department with modern manufacturing technologies in machining, grinding, and EDM, as well as specially qualified personnel who understand and implement the specific requirements of the MIM process.

Multi-cavity molds enable economical series production at high volumes. Through precise design of the gating, cavity geometry, and temperature control, we ensure uniform filling of all cavities and reduce component variation. This optimizes cycle times while ensuring reproducible quality over the entire lifetime of the mold.

The advantages of in-house tool making: tools are built in close proximity to production, changes are implemented quickly and without interface losses, and complex repairs to production tools can be carried out promptly – without production downtime for the customer.

Machining

Finish machining – turning a sintered part into a ready-to-install component

The sintering process delivers components with high dimensional accuracy – but not every application can be served directly with the as-sintered component. Schunk Sinter Metals masters the full spectrum of finish machining:

Heat treatment

Case hardening and direct sinter-hardening selectively increase the surface hardness and wear resistance of sintered components – for applications with high tribological demands such as gears, cams, or bearing caps.

Machining

Turning, grinding, and thread cutting for functional surfaces that cannot be produced with the required precision during pressing – tailored to the specific properties of sintered metals.

Surface finishing

Impregnation with oil or resin for self-lubricating properties or media tightness, steam treatment for improved corrosion protection, surface coating, as well as cleaning and washing for technical cleanliness in line with IATF requirements.

Additional processing options

Joining of assemblies, vibratory finishing for uniform surfaces, brushing, as well as green part machining for geometries that cannot be produced directly in the tool.
