  Metal Injection Molding (MIM) process is a manufacturing process that marries the versatility of plastic injection molding  with the strength and resilience of powder metallurgy . MIM offers a unique proposition for mass production, enabling the creation of complex, precision parts across various industries. This blog aims to comprehensively understand the MIM process, its pros and cons, and the critical considerations for mass production. What is Metal Injection Molding Metal Injection Molding (MIM) is a transformative manufacturing technology that has been shaping the industrial landscape for decades. But what exactly is MIM, and how has it evolved? Let's delve into MIM's definition, history, and role in various industries. Definition and History MIM is a process that combines the high-volume capability of injection molding with the benefits of metallic materials. It involves mixing metal powders with a binder to form a feedstock, which is then injected into a mold to crea

  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
