Injection molding

In addition to conventional press and sinter powder metallurgy processing, Multi-Metals offers a unique way of forming carbide via injection molding.

Any carbide grade can be injection molded and parts with complex geometry and/or small section thicknesses are ideal candidates.

Injection molding

IM parts

Cemented tungsten carbide powder is blended with polymeric binders to give the mixture proper flow characteristics. This feedstock is then injection molded into tool cavities using plastic injection molding equipment under controlled conditions.

The binder from the molded parts is then removed under closely controlled conditions, leaving a porous part. This part is then sintered either in vacuum or controlled atmosphere conditions to produce parts that are fully dense.
