Ceramic Powder Injection Molding

Powder injection molding of metal and ceramic parts 67 the starting material for pim usually termed feedstock is a homogeneous pelletized mixture of metal or ceramic powder and an organic multi component binder.

Ceramic powder injection molding. Powder injection molding is a near net shape manufacturing technique for complex metal or ceramic components. Powder injection molding pim enables the cost effective series production of durable precision metal mim or ceramic cim parts. The major benefit of the multistage process. First through a combination of plastic wax and metal or ceramic powder a material is generated which can be processed by injection moulding.

The binder is used for the artificial plasticisation of the ceramic powders and for the formation of the desired shape through injection molding. By custom machine and tool technology this feedstock can be injected similar to. The ceramic injection molding process begins with very fine ceramic powders. The first step in the manufacturing process figure 1 is the careful choice of the ingredients of the compound that in general consists of a polymeric binder system and the metal or ceramic powder.

Ceramic injection molding is an innovative new process at indo mim under a six sigma controlled environment. What is ceramic injection molding cim. 1 when powder technologies are in question the key step in production process is choosing the adequate ceramic powder. Feedstock preparation injection molding debinding process and sintering fig.

Cim is also a good option when you need to replace plastic and. This material is generally named feedstock. There are additional manufacturing processes after the molding but the process starts. Using a blended powder product called feedstock which is made from alumina and a binder material the feedstock is forced into a mold of the finished part under high pressure and literally molded into the desired shape.

Using sophisticated mixing technology the powders are compounded with thermoplastic binders to produce a homogeneous pelletised feedstock. The ceramic injection molding process consists of four basic steps. The binders form a liquid medium which carries the ceramic powders into the mould during. Before the injection molding the powder is mixed with binder to form a homogeneous mixture that is used to form the shape of the capillary.

The binder and the powder are combined in a variety of compounding equipment such as extruders and mixers. Ceramic injection molding is ideal for high volume production of complex tight tolerance components. The cim process gives production engineers and product designers more versatility in the use of ceramics as an alternative material with higher productivity lower manufacturing cost s and improved product performance.
