For the glue of the MIM, it is the core of the MIM technology. In the MIM, adhesives have two basic functions: they enhance fluidity to fit injection molding and maintain the shape of the billet. In addition, it should also be easy to remove, pollution-free, non-toxic, reasonable cost characteristics. As a result, various adhesives have emerged. In recent years. It is gradually changing from a simple adhesive to a non-toxic one.

Adhesives are usually composed of low molecular weight components, polymer components and some necessary additives. Low molecular component viscosity, good fluidity, easy to remove; Polymer components have high viscosity, high strength, and can maintain the strength of the formed billet. In order to obtain a high powder load, a high precision and uniform product can be obtained by matching them.
