  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

  Magnetic Alloy Metal Injection Molding Magnetic Alloy Metal Injection Molding (MIM) is a cutting-edge manufacturing process offered by Neway that combines the versatility of plastic injection molding with the superior properties of magnetic alloys. It involves finely powdered MIM magnetic alloy materials , such as MIM-Fe-50Ni, MIM-Fe-3Si, and MIM-Fe-50Co, mixed with a binder to form a feedstock. This feedstock is then injected into molds with high precision. After shaping, the components undergo a debinding and sintering to achieve their final metallic form. MIM enables intricate geometries, exceptional magnetic characteristics, and high production efficiency, making it an ideal solution for various industries. Magnetic Alloy Optional for MIM MIM-Fe-50Ni Magnetic Strength: Exhibits high magnetic flux density, ideal for applications requiring strong magnetic properties. Thermal Stability: Maintains magnetic performance even under varying temperature conditions. Applications: Suited

  Definition of Metal Injection Molding (MIM) Metal injection molding (MIM ) is an advanced powder metal injection molding (PMIM) manufacturing process that produces small, complex metal parts to tight tolerances and high densities. In MIM, metal powders are combined with polymer binders to create a feedstock material that can be injected into molds using plastic injection molding techniques. After molding, the binders are removed through debinding of MIM parts, and the metallic component is sintered at high temperatures to fuse the particles into a solid metal part. Importance of metal selection in MIM Metal selection is crucial in metal injection molding  as it fundamentally impacts feedstock properties, molding behavior, debinding, sintering characteristics, final part properties, and secondary operations. The specific alloy composition and powder morphology drive important factors like densification, shrinkage, mechanical performance, machinability, corrosion resistance, cost, an
