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 process that merges the design flexibility of plastic injection molding with the strength and durability of metal. It begins with fine metal powders mixed with a binder to create a moldable feedstock. This mixture is injected into intricate molds using specialized machines, forming a “green part.”
After debinding and sintering, the component becomes a high-density metal structure with exceptional strength. MIM is ideal for producing complex geometries and high-precision parts, offering a cost-effective alternative to CNC machining and casting, especially for large-scale production.

Metal Injection Molding (MIM) manufacturing Process
Molding
Metal Injection Molding (MIM) utilizes a process akin to plastic injection molding, employing similar equipment. In this method, a pelletized feedstock—composed of fine metal powders blended with a binder—is heated to around 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. Using 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, the component enters the debinding phase, where binder materials are carefully removed to maintain 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.
