We offer sintered components according to customerdrawings in iron, steel, stainless steel, differenct copperbased alloys and SMC (Soft Magnetic Composites).
After compaction the components must be sintered to give them the required properties.
Sintering provides the final mechanical properties, while both the magnetic properties (for soft magnetic components) and the corrosion resistance of stainless steel components can also be considerably affected.
Sintering is usually performed in a belt conveyor furnace in a controlled atmosphere.
Sintering is a type of heat treatment which normally is carried out at a temperature a few hundred degrees below the melting point of the base material. Thus, steel is generally sintered at 1120 °C.
During sintering the powder grains in the components grow together through a process of atomic diffusion and the final properties emerge.
Apart form minor sintering shrinkage the component geometry formed during compaction is retained.
Sintering is performed under a gaseous shield and under precisely controlled conditions in a furnace consisting of a preheating zone (where the lubricant in the powder mixture is expelled), a sintering zone and a cooling zone.
Sintering brings to an end the basic powder metallurgical process.
Depending on the requirements placed for the finished components, they are often subjected to one or more after-treatment processes.
There are several types of powder compaction. At Dansk Sintermetal A/S we only use conventional powder compaction in fixed tools.
In the process the powder is ...

The silencer can be used for all valves, cylinders and in compressed air units where there is noise. The SIVANI silencer is manufactured in dimensions to fit ...
We offer sintered components with surfacetreatment.
We produce selflubricating bronzebearings.
Steam treatment or black oxidation is a process which uses the porosity of sintered components. Components are treated in dry steam at approx. 550° C, where the ...
Powder-compacted components of soft magnetic materials are being increasingly used in both AC and DC applications.
The primary reason is that powder compaction ...
