Axial Pressing Technology

Precision across the board – sintered structural parts and sintered bearings from Schunk Sinter Metals

Our customers benefit from the advantages of our continuously enhanced sintering technology, our 90 years of experience and in particular from our sinter know-how through. Our product portfolio ranges from sintered bearings weighing fractions of a gram for micro motors to complex structural parts weighing several kilograms.


Metal Powder

Base powder – pure metals and alloys

We exclusively use metals and alloys of leading powder manufacturers. Our quality inspection guarantees that the powder fulfils the specified powder properties such as flow, fill and compression characteristics.


Mixing

Ready-made mixtures and our own mixtures

All mixtures are produced from specially-developed and strictly-defined formulas. This allows us to ensure that all our materials meet the high quality standards of the automobile industry. We define customized material properties together with you for your products and design them in a manner compatible with your application and with sintering technology.


Pressing

The use of mechanical, hydraulic and electric presses. Pressing forces of 30 to 8,000 kN

In our presses powder is compacted in molding tools into workable components called green parts. As we have mechanical, hydraulic and electric presses, we can select and use the press which is best suited to your special component.


Sintering

The highest degree of strength and dimensional accuracy through „hardening in the sinter heat“

The green parts form firmly-bonded contacts through diffusion processes during the heat treatment, or what we call sintering. By hardening in the sintering furnace, we achieve top values for strength and dimensional accuracy. Changes in dimensions (volumes, increase in length or shrinkage) are precisely pre-calculated and taken into consideration when designing the molding tool.


Finishing and Refining

We deliver ready-to-install components

The refining competences of Schunk Sinter Metals go well beyond the commonly-used finishing processes such as machining, calibrating, surface treatments, impregnation, thermal aftertreatments, etc. For example, it can be advantageous to carry out machining procedures on so-called green parts to enhance the effectiveness of finishing work. We decide on and individual basis together with you what refinement procedures are most technologically and economically sensible for your component and application.
