Introduction to the mixing process of metal powder injection molding

Metal powder injection molding (MIM) can produce many has the characteristics of precision and complex shape parts, such as various external grooving, male, powder metallurgy micro gear and powder metallurgy small module gear, etc., and in the process, mixing is a key working procedure, the next big macro new materials for you detailed introduce what is mixed metal powder injection molding, and how the process.

I. what is mixing

Mixing is the process of mixing metal powder with binder to get uniform feeding. The MIM technical experts of daihong new materials have found that the mixing process is of great importance because the feeding properties will affect the performance of the injection molding products. This involves a variety of factors such as the way and order in which the binder and powder are added, the mixing temperature, and the characteristics of the mixing device.

Ii, mixing device

The commonly used mixing devices include double screw extruder, z-shaped impeller mixer, single screw extruder, plunger type extruder, double planet mixer, double CAM mixer, etc.

Iii. Mixing process

Mixing method is generally the first to add high melting point components melting, and then cooling, adding low melting point components, and then batch adding metal powder. This can prevent gasification or decomposition of components with low melting point, and the addition of metal powder in batch in MIM mixing process can prevent the rapid increase of torque caused by too fast cooling and reduce the loss of equipment.

The above is the introduction of metal powder injection molding mixing process, we hope you can pay more attention to dahong new materials co., LTD., if you have any technical problems, welcome to consult dahong new materials technical team, will provide you with good solutions and services.
