Is MIM Right For You?

Most of the time, complexity is never an obstacle for metal injection molding. Not only that, but it also enables us to produce parts in short periods. However, it may not be the right manufacturing method for every component.

Components must meet certain limitations such as weight and size to carry out an economical production. Even though these factors are negligible for metal injection molding, it may not be preferred due to its low-cost policy.

The overall precision of Metal Injection Molding production is considered to be between 3% and 5%. The precision that cannot be achieved after the process is completed can be achieved through various finishing processes.

Parts to be produced with Metal Injection Molding should not weigh more than 200 grams for economic production. Although the manufacturing of heavier parts is possible, it is challenging to manufacture economically. For some components, it may be possible to achieve an economical cost by reducing the weight of the parts.

Not only the weight, but the size of a component is also a matter in MIM. The larger and thicker the parts, the fewer components that can be placed into the furnace, and longer the process takes for each batch. To be economical, we recommend working with our engineers to optimize your part for the MIM process.

Thousands or millions of parts can be produced economically and quickly with MIM. However, as it is in standard manufacturing methods, MIM also has mold cost, and it is recommended to consider the mold investments for low-volume parts.
