FAQ
Here are some of the questions we get asked often. If yours isn’t answered, don’t hesitate to contact us, we’re happy to help!
-
How does MIM differ from conventional injection molding, machining, and die casting?
-
Compared to injection molding: MIM produces metal parts with significantly higher strength and hardness than plastic parts. Compared to machining: MIM is ideal for small, intricate, or multi-cavity parts, offering higher material utilization and lower per-unit costs in mass production. Compared to die casting: MIM supports a wider range of materials (e.g., stainless steel, titanium, superalloys), achieves higher density (≥95%), and delivers superior mechanical properties.
-
How do you ensure the quality of the parts you manufacture?
-
We apply full-process quality control across every stage: incoming material inspection, mold precision verification, MIM process parameter monitoring, debinding & sintering control, CNC/turning tolerance checks, and final surface treatment with dimensional measurement. Each batch undergoes AQL sampling inspection, and we provide full material certifications and inspection reports on request.
-
What is your experience with high-precision parts?
-
We have extensive experience producing high-precision MIM parts for 3C electronics, medical devices, and automotive applications — with tolerances as tight as ±0.02mm and surface roughness down to Ra 0.4μm after polishing. Our precision is backed by CNC machining, CNC turning, and coordinate measuring equipment, ensuring consistent quality even at high volumes.
-
What is the maximum complexity achievable with MIM?
-
MIM allows the production of highly complex geometries, including internal cavities, undercuts, thin walls, fine teeth, and intricate 3D structures that would be difficult or expensive to manufacture using traditional machining.
