MIM how to select binder?

Binder is the core of MIM technology, and MIM is an important difference compared with conventional powder metallurgy method. The main function of the binder is to act as a carrier for the flow of the bonded metal powder particles and to maintain the shape of the workpiece.

MIM binder should meet the following requirements:

The contact angle of the powder is small, and the adhesion ability is strong, and the reaction is not with the powder;

Injection temperature range of viscosity change is not big, but the cooling viscosity change fast

Non stick mould;

With less dosage, the mixture can produce better rheological properties with less binder;
