Surgical Forceps Head Manufactured via MIM
Client: Global Medical Device Manufacturer —New Jersey, USA ←2025
The Challenge
A leading medical device company needed to produce complex surgical forceps heads with integrated jaw serrations, a ratchet locking mechanism, and ergonomic finger ring geometry. The part required 316L stainless steel for biocompatibility, with mirror-polished surfaces and dimensional accuracy of ±0.02mm on mating features. The previous manufacturing method involved multi-step CNC machining with extensive hand finishing, resulting in high costs and quality inconsistency.
Our Solution
We implemented a specialized MIM process using medical-grade 316L powder with optimized binder formulation. Our tooling design incorporated the complex serration patterns and undercuts directly into the mold, eliminating the need for EDM. A two-stage sintering process with controlled atmosphere achieved full densification while maintaining precise dimensional control. Post-sintering tumbling and electropolishing provided the required surface finish.
Results
70% cost reduction vs. CNC machining, ±0.02mm dimensional accuracy on critical features, Ra 0.2μm surface finish after electropolishing, 316L biocompatibility certified per ISO 10993, production volume of 500,000 units/year, 99.7% first-pass yield.
"YuJiaxin Tech revolutionized our surgical forceps production. The MIM process delivered consistent quality that hand-crafted methods could never achieve at scale."
