MIM is Metal Injection Molding, a metalworking process in which finely-powdered metal is mixed with binder material to create a “feedstock” that is then shaped and solidified using injection molding. The molding process allows high volume, complex parts to be shaped in a single step. After molding, the part undergoes conditioning operations to remove the binder (debinding) and densify the powders. Finished products are small components used in many industries and applications.
Due to current equipment limitations, products must be molded using quantities of 100 grams or less per “shot” into the mold. This shot can be distributed into multiple cavities, making MIM cost-effective for small, intricate, high-volume products, which would otherwise be expensive to produce. MIM feedstock can be composed of a plethora of metals, firstly the most common material is stainless steels which is widely used in powder metallurgy, but now a few enterprises master the mature producing technology of using Brass and Tungsten alloy as material, and make the MIM products has more performance and wide use in various industries. KELU is the who has capability to use Brass, Tungsten and Stainless Steels as MIM materials for mass production. After the initial molding, the feedstock binder is removed, and the metal particles are diffusion bonded and densified to achieve the desired strength properties.
The advantages of MIM is realizing the small parts with high efficiency in mass production, and having the tight tolerance and complexity at the same time. On the final products, we can use different surface treatments to get different surface effect to match different requirements.
