metal injection molding
Metal injection molding (MIM) is a manufacturing process that combines the versatility of plastic injection molding with the properties of metal. In this technique, fine metal powders are mixed with a binder material to create a feedstock. This feedstock is then injected into a mold to form complex shapes.
After molding, the parts undergo a two-step process: debinding and sintering. During debinding, the binder is removed, leaving behind a porous metal part. In the sintering stage, the part is heated to a temperature below its melting point, allowing the metal particles to fuse together, resulting in a dense and strong final product.
