Mixing
Mix <20 µm typical powder with polymer (binder) system to produce the MIM feedstock. Theoretically speaking, the smaller the particle is, the bigger its specific surface will be, which is good for molding and sintering.
Granulation
The evenness of the mixture directly influences its fluidity and further influences the technical parameter of the injection molding, and the density and other performances of the final material.
Molding Injection
Mold complex components from the feedstock using standard plastic injection molding equipment & techniques. During injection molding, the mixture is heated in the injection molding machine into plastic material with rheology, and then injected into the mold under certain pressure to mold a blank.
Sintering/Debinding
Remove the plastic binder by sintering parts in a high temperature H2/N2 pusher furnace. The high density of MIM component is achieved through high sintering temperature and long sintering time, which greatly improves the mechanical property of the component.
Secondary Operations
Parts can be machined, coined, heat treated, plated, and black-oxided and so on.
Considering the performance requirements on product strength, corrosion resistance, heat conductivity coefficient, density, hardness, etc., as well as the applications of the products, we will provide suggestions in the selection of materials and alloys. HZMIM provides various alloys, used for various industries such as automobiles, electronics, medical and tool accessories. When necessary, we can also create the customized alloys.
The injection molding materials include:
17-4PH (Sintered state) | 17-4PH (Heat treatment) | 316L | 310 N2-sintered | 310 Ar-sintered | 420 (Heat treatment) | 430 | 440 |
1110 | 4140 (Sintered state) | 4140 (Heat treatment) | 4605 (Sintered state) | 4605 (Heat treatment) | FN02-2% Nickel Steel | FN08-8% Nickel Steel |
430 | FeSi3 | FN50-50% 20Nickel Steel | Pure%20 Ir |
