FAQs About Metal Injectiom Molding-TWO

5, Does the part shrink during the debinding?

No, there is shrinkage during the sintering, it’s roughly 20% smaller. But don’t worry about that, the powder-binder ratio is closely controlled, the feedstock consistency results in predictable uniform and isotropic shrinkage.

6, Why do you use MIM?

MIM is suitable for the parts with high precision and complex geometry, that conventional manufacturing technologies can’t make, such as forging, die castiong, etc.

7, what materials can be used in MIM?

Almost all kinds of metal alloy can be used in the MIM process, normally including high strength steels, stainless steels plus Ni and Co super alloys. Other materials processed include refractory metals, titanium and copper alloys.

8, What is the lead-time for MIM?

Theoretically, the lead-time for tool building and sample submission is 30-40 calendar days. However it depends on the structure of the part.

9, Are there any limitations in MIM?

Sure, as with other conventional technologies, there are some limitations for MIM. Generally, MIM is limited to parts less than 450g ( no more than 50g economically and effectively) in weight.

10, What tolerances can MIM achieve?

Typical MIM tolerances range from ± 0.3% to 0.5% of the dimension. In detail, tolerances highly depends on product geometry. Tolerances beyond that can be achieved by afterward machining.

11, What surface treatments can be done?

The part made by MIM can be plated, blackened, polished, heated, passivated, chromed, etc as done as the part made by conventional manufacturing technologies.
