This precision-engineered MIM medical scissor handle is manufactured via advanced Metal Injection Molding technology from high-grade medical stainless steel, specifically designed for surgical instruments, dental tools and clinical devices. Combining the design flexibility of plastic injection molding with the exceptional mechanical strength of metal, our metal injection molding medical scissor handle delivers complex, ergonomic geometries at scale—ideal for high-precision, biocompatible medical components that demand consistent quality and cost efficiency. All our products meet ISO 10993 and ASTM F138 medical standards, ensuring safety and reliability in clinical applications.
Crafted from premium 316LVM stainless steel (or 17-4 PH for high-strength applications), our medical scissor handles are certified for biocompatibility, superior corrosion resistance and full compatibility with standard sterilization methods including autoclave and ethylene oxide. This ensures long-term performance even with repeated sterilization cycles, critical for reusable medical instruments.
Our MIM process enables near-net-shape production of complex thin-wall geometries that would be prohibitively expensive or impossible with traditional machining methods. We achieve tight tolerances of ±0.02mm for as-sintered features, eliminating most secondary operations and reducing overall production costs while maintaining exceptional dimensional consistency across large production runs.
Every handle features an ergonomic finger loop design optimized for extended use, reducing hand fatigue for medical professionals. All surfaces undergo rigorous deburring and edge rounding to create smooth, patient-safe contours with a surface roughness of Ra ≤0.8μm, minimizing irritation and bacterial adhesion.

We use fine medical-grade metal powder with a particle size of D50 < 15μm, mixed with a proprietary thermoplastic binder system to create a homogeneous feedstock. This ensures uniform flow during injection molding and consistent sintering performance, critical for producing complex thin-wall geometries with uniform mechanical properties.
High-precision tool steel molds (H13/SKD61) are CNC-machined to replicate every detail of the handle design, including finger loops and pivot holes. The feedstock is injected under precisely controlled pressure and temperature to form "green parts"—near-net-shape replicas with complete geometric detail.
Green parts undergo a two-stage debinding process: solvent extraction removes the majority of the binder, followed by thermal debinding to eliminate residual polymer. The resulting "brown parts" are then sintered in a controlled-atmosphere furnace at 1350–1400°C, densifying to >97% theoretical density and achieving mechanical properties equivalent to wrought stainless steel.
Critical features such as pivot holes and mounting interfaces are CNC-machined to achieve ±0.01mm tolerances. Automated vibratory deburring and hand finishing remove all sharp edges, followed by electropolishing and nitric acid passivation to enhance corrosion resistance and create a bright, smooth surface.
Every batch of surgical instrument MIM parts undergoes comprehensive quality control to ensure compliance with medical standards. We use Coordinate Measuring Machines (CMM) to validate all critical dimensions against CAD specifications, and optical profilometry to verify surface roughness. Our stringent quality management system is certified to ISO 9001 and AS9100, ensuring consistent quality across all production runs.
