1. What is MIM technology?
MIM (Metal Injection Molding) is a manufacturing technology that combines the shape making complexity of Plastic Injection Molding with the material flexibility of Powder Metallurgy.
2. Is the metal melted during the molding process?
No, only the binders are melted allowing the powders to flow like a plastic material. Upon cooling the binders solidify giving the part strength for handling. The part must be subsequently sintered to high density to achieve the required mechanical properties.
3. How does MIM differ from the Conventional PM process?
Conventional PM uses high, uniaxially applied pressure to coarse metal powders in a die set to produce moderately complex components. Typically, no further densification is gained during the sintering process. Densities achieved by this method are typically in the range of 80-90% of theoretical which limit the physical properties that can be achieved for the given alloy. MIM products are not limited in shape complexity due to the flexibility of the injection molding process. The fine metal powders used - combine with higher sintering temperatures to allow MIM to achieve near full density in the final article. This allows MIM products to have similar properties as wrought materials.
4. Does the part shrink during removal of binders?
No, the part will not change size in the debinding phase of the process. However, since sintering achieves near full density of the powders, the part will undergo a size change of up to 20%.
5. Why should I use MIM?
MIM excels in producing small, highly complex parts that are difficult or cost prohibitive to produce with conventional technologies such as machining or casting.
