Ceramic Powder Injection Molding

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 powder injection molding.

The binders form a liquid medium which carries the ceramic powders into the mould during. Ceramic injection molding. 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. The ceramic injection molding process begins with very fine ceramic powders.

There are additional manufacturing processes after the molding but the process starts. Using sophisticated mixing technology the powders are compounded with thermoplastic binders to produce a homogeneous pelletised feedstock. This material is generally named feedstock. First through a combination of plastic wax and metal or ceramic powder a material is generated which can be processed by injection moulding.

Feedstock preparation injection molding debinding process and sintering fig. 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. What is ceramic injection molding cim. 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 is used for the artificial plasticisation of the ceramic powders and for the formation of the desired shape through injection molding. 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. With us as your partner you can successfully interlink all process steps. Cim is also a good option when you need to replace plastic and.

The ceramic injection molding process consists of four basic steps. Ceramic injection molding is ideal for high volume production of complex tight tolerance components. By custom machine and tool technology this feedstock can be injected similar to. 1 when powder technologies are in question the key step in production process is choosing the adequate ceramic powder.

The binder and the powder are combined in a variety of compounding equipment such as extruders and mixers. The major benefit of the multistage process. Ceramic injection molding is an innovative new process at indo mim under a six sigma controlled environment.
