  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...

 Metal Injection Molding (MIM) is a new type of metal injection molding near-net forming technology derived from the plastic injection molding industry. MIM combines the advantages of plastic injection molding , such as low cost and the ability to produce precision, complex shapes, with the advantages of powder metallurgy , such as high strength and good wear resistance metal forming. What is Metal Injection Molding (MIM)? The MIM process begins with mixing metal powder and a binder material. The mixture is then injected into a mold using a plastic injection molding machine. The molded part is then subjected to a debinding process, in which the binder is removed. Then is the sintering process , which is a process that causes the metal powder to bond together and form a solid part. MIM is a versatile process that can produce various metal parts. MIM parts are used in various industries, including automotive, aerospace, medical, and electronics. Although MIM is suitable for...
