Metal Injection Molding (MIM) manufacturing Process
Molding
The Metal Injection Molding (MIM) process is closely aligned with plastic injection molding, utilising comparable equipment and techniques. It begins with a pelletised feedstock, made from fine metal powders mixed with a thermoplastic binder. This mixture is heated to approximately 200°C and then injected at high pressure into a mould, forming what’s known as a “green part.”
Once cooled, the green part is ejected from the mould, allowing for efficient, continuous production. The binder plays a crucial role in ensuring uniform distribution of metal particles, while multi-cavity moulds significantly boost productivity for high-volume manufacturing.
To compensate for material shrinkage during the sintering stage, mould cavities are typically designed about 20% larger than the final component. This shrinkage is precisely calculated based on the material formulation, ensuring excellent dimensional accuracy in the finished product.
Debinding
After the injection molding stage, the component undergoes debinding, a crucial step where binder materials are carefully removed without compromising the part’s structural integrity. Solvent extraction is commonly used to dissolve and eliminate a significant portion of the binder, helping to minimise distortion and preserve the shape of the component.
Post-debinding, the part becomes semi-porous, allowing any remaining binder to escape during the subsequent sintering process. This controlled, two-step approach ensures a seamless transition, resulting in a final component with high mechanical strength and precise dimensional accuracy.
Sintering
Following debinding, components are carefully positioned on ceramic setters and placed into a high-temperature sintering furnace. During this critical phase, any remaining binder is fully vaporised, leaving behind a clean metal matrix primed for densification.
As the temperature rises, metal particles bond through solid-state diffusion, closing internal voids and enabling uniform shrinkage. The outcome is a dense, high-integrity component, often exceeding 97% of its theoretical density. These final parts demonstrate mechanical properties on par with wrought metals, delivering exceptional strength, durability, and reliability in even the most demanding applications.
