We have gathered the questions we most frequently receive about Metal Injection Molding technology, our production processes and our collaboration model. If you cannot find what you are looking for, do not hesitate to contact us directly.
Metal Injection Molding (MIM) is an advanced manufacturing technology that enables small and precise metal parts with complex geometries to be produced at high volumes with repeatable quality.
In the MIM process, fine metal powders are combined with a special binder system to create the raw material called feedstock. This material is injected into special MIM tooling in a manner similar to plastic injection molding. The part then undergoes debinding (binder removal) and sintering processes to gain its final density and mechanical properties.
Thanks to its high precision, ability to produce complex geometries, suitability for volume production and high repeatability, MIM offers a strong alternative to conventional machining, casting and other methods.
MIM offers a strong alternative to CNC machining, especially in projects where small and medium-sized parts with complex geometries are produced at high volumes. For parts with internal channels, thin sections, multiple surfaces or details that are difficult to machine with CNC, MIM reduces the cost per part after the tooling investment.
Decision guide:
The right method should be selected by evaluating part geometry, material, tolerances, production volume, surface requirements and target cost together. At MIMCorex, we evaluate all these project parameters with an engineering approach.
With MIM technology, high dimensional precision and repeatability are achieved depending on part geometry and process conditions. In general, dimensional tolerances in the order of ±0.3% – ±0.5% can be targeted in the MIM process.
For critical dimensions, tighter tolerances can be achieved by optimizing tool design, material selection, injection parameters and the sintering process. After the process, tolerances can be further tightened by applying CNC machining, grinding or other precision finishing operations.
Main factors determining tolerance performance:
The tolerance achievable in MIM should not be considered a single standard value, but should be evaluated on a project basis using the part's technical drawing and production requirements.
At MIMCorex, we can process various metal alloys suitable for the part's intended use, mechanical properties and production requirements:
Yes. With proper material selection and an optimized sintering process, the density of MIM parts can reach values very close to those of wrought steel of the same alloy. Density values of 96%+ are generally achieved.
During sintering in the MIM process, bonds form between the metal particles and the part densifies in a controlled manner. This achieves high density and, consequently, high mechanical performance.
MIM is a strong production technology not only for manufacturing complex geometries, but also for serial production applications where high density, mechanical strength and repeatable properties are required.
MIM technology offers significant advantages in the production of thin-walled parts with complex geometries. With suitable material, tool design and process conditions, wall thicknesses of approximately 0.2 – 0.5 mm can be achieved.
The minimum achievable wall thickness varies depending on part geometry, wall length, material type, flow characteristics, tool design and injection conditions. Particularly in long and thin walls, filling behavior, possible deformation during sintering and dimensional stability must be evaluated together.
During the design stage, our engineers evaluate your part's geometry and manufacturability to determine the optimum wall thickness and process conditions.
Absolutely. We offer a "one-stop solution". The operations we apply after the MIM process:
All these operations are carried out at our own facility, and your part is delivered to you ready for use.
The typical lead time for a new MIM project depends on several stages:
Typically, the tool design and sampling stage (from green part to sintered part) takes 6 to 10 weeks. After samples are approved, serial production times depend on volume but generally range from 4 to 8 weeks.
