Understanding MIM Shrinkage The shrinkage in Metal Injection Molding (MIM) is a critical consideration in the manufacturing process. During MIM, metal powders are mixed with a binder to create a feedstock, which is then molded into the desired shape. After molding, the parts go through a debinding process to remove the binder, and then they are sintered at high temperatures to achieve the final metal part. Shrinkage in MIM occurs primarily during the sintering phase . During sintering, the metal particles in the feedstock bond together and densify, causing the part to shrink. The shrinkage can vary depending on several factors, including the material used, the specific MIM process parameters, and the part's geometry. Typically, the shrinkage in MIM falls within the range of 15% to 20%. It means a part initially molded will reduce size by 15% to 20% during sintering. The mold used for MIM is designed to produce parts slightly larger than the final specifications to compensate fo...
