Ceramic Powder Injection Molding

The binders form a liquid medium which carries the ceramic powders into the mould during.

Ceramic powder injection molding.

Using sophisticated mixing technology the powders are compounded with thermoplastic binders to produce a homogeneous pelletised feedstock. The binder is used for the artificial plasticisation of the ceramic powders and for the formation of the desired shape through injection molding. The powder injection molding is divided into four production steps. Feedstock preparation injection molding debinding process and sintering fig.

The major benefit of the multistage process. This material is generally named feedstock. Powder injection molding is a near net shape manufacturing technique for complex metal or ceramic components. The ceramic injection molding process begins with very fine ceramic powders.

First through a combination of plastic wax and metal or ceramic powder a material is generated which can be processed by injection moulding. 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. There are additional manufacturing processes after the molding but the process starts. The ceramic injection molding process consists of four basic steps.

Powder injection molding pim enables the cost effective series production of durable precision metal mim or ceramic cim parts. 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 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. The binder and the powder are combined in a variety of compounding equipment such as extruders and mixers.

With us as your partner you can successfully interlink all process steps. Ceramic injection molding is ideal for high volume production of complex tight tolerance components. Cim is also a good option when you need to replace plastic and. 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.

1 when powder technologies are in question the key step in production process is choosing the adequate ceramic powder. 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. What is ceramic injection molding cim.
