CIM technique is regarded as the preferred net-shape
manufacturing method for making many precision engineering
and electrical ceramic components. CIM Materials Specs

The Technology
The CIM process involves the mixing of selected ceramic
powder with binders to form the feedstock, which is
then moulded in a die cavity to form the required
component shape.
These shapes undergo a debinding
process where binders are removed by using either
thermal evaporation or solvent washing. The parts
are then consolidated in a sintering furnance at temperatures
up to 1800°C, under either oxidising or reducing
atmospheres.
The Advantages
CIM technology is most advantageous especially when
conventional machining methods are too expensive or
incapable to perform. It is ideal for parts that are
of a complex shape and where high throughput rate and
consistent quality are crucial.
Using sub-micron
ceramic power, CIM-products have high surface finish,
very fine grain structures and close to theoretical
densities.
The Applications
The applications of CIM process are virtually boundless.
As ceramic possesses high flexural strength, hardness
and chemical inertness, it yields products that are
of high corrosion resistance, wear resistant and have
a long life span. Ceramic products are used in electronic
assembly, tools, optical, dental, telecommunications,
instrumentation, chemical plants and textile industries.
