How Metal Injection Molding Works?
Let’s Discuss Your Metal Injection Molding (MIM) Needs With Us
What is Metal Injection Molding?
Metal Injection Molding (MIM) is an advanced manufacturing technique that combines the versatility of plastic injection molding with the robustness of metal. The process starts by blending fine metal powders with a binder to produce a moldable feedstock. This mixture is then injected into detailed molds using specialized machinery, forming what is known as a “green part.”
Following the initial molding, the binder is removed through debinding, and the component undergoes sintering, resulting in a high-density metal structure with exceptional strength. MIM is particularly well-suited for creating complex geometries and high-precision parts, offering a cost-effective alternative to CNC machining and casting, especially in large-scale production.

Metal Injection Molding (MIM) manufacturing Process
Molding
Metal Injection Molding (MIM) employs a process similar to plastic injection molding, utilizing comparable equipment. In this method, a pelletized feedstock—comprising fine metal powders mixed with a binder—is heated to approximately 200°C and injected under high pressure into a mold cavity, forming a “green part.” After cooling, the part is ejected, and the cycle repeats efficiently.
The binder ensures uniform distribution of metal powders during injection. Utilizing multi-cavity molds enhances production efficiency, enabling high-volume output. To account for shrinkage during the subsequent sintering process, mold cavities are designed approximately 20% larger, with precise shrinkage rates calculated based on the specific material composition used.
Debinding
After injection molding in the Metal Injection Molding (MIM) process, the component undergoes debinding to remove binder materials while maintaining structural integrity. Solvent extraction is a commonly employed method for efficient binder removal. Following debinding, the part becomes semi-porous, allowing any remaining binder to escape during sintering. This process ensures a clean, precise, and high-quality final product with superior mechanical properties.
Sintering
After debinding, components are placed on ceramic setters and loaded into a sintering furnace operating at high temperatures within a controlled atmosphere. The parts are gradually heated, allowing any remaining binders to vaporize completely. Once the binders are removed, the temperature is elevated to facilitate the fusion of metal particles, eliminating voids and ensuring uniform shrinkage. This process results in a dense, solid structure with a density exceeding 97% of the theoretical value, imparting mechanical properties comparable to wrought materials.
