Our Technology: shaping powders by injection moulding

METALS-CERAMICS-COMPOSITES

The technology is an elegant blend of fine particle science, polymer science, theory of advanced low and high pressure injection, high - energy diffusion science, material science and metallurgy. Fine particulate materials are blended to form the design alloy, while the particle size distribution is matched to the design and sintering characteristic of the component. The high surface energy fine particles are thermally activated to form bonding necks between them. The shape retention is transferred from the binder to the necks, prior to the complete removal of the polymeric binder system from the moulded green body. The bonds are strengthened and grown into full density structure during the high energy diffusion sintering, The result is the transformation of powder into a full density, net shape, high precision complex metal or a ceramic or composite component with multiple design properties.

The MIM / CIM materials have pesudoplastic behavior in contrast to plastics which are Newtonian fluids. As such the injection system has been modified to suit the rhelogical properties of MIM/CIM feedstock. Moving further, the cavity steels for MIM have been bench marked. The venting systems and the thermal management systems have been redefined noting the high thermal conductivities and the binder systems of the MIM/CIM feedstock. These collectively defines Ceramet's leading and unique MIM / CIM technologies and capabilities.
