Precision Surgical Instrument Manufacturing: Solving Your Toughest Challenges

 
From CNC Machined Scissors to Implant Components — Compliance, Durability, Precision Guaranteed
Dakings specializes in high-precision surgical instruments (scissors, forceps, robotic end-effectors) and critical components, addressing industry pain points: tight tolerances, biocompatibility, and rigorous regulatory compliance. Our expertise spans material selection, complex machining, and surface treatment to meet the demands of OR, robotic, and implantable medical devices.

Our Surgical Instrument Manufacturing Capabilities

 
Manufacturing Technologies for Surgical Excellence
  • Precision CNC Machining
    5-axis milling/turning for complex geometries (e.g., thin-walled lens holders, 0.05mm wall thickness) — minimizing deformation via optimized toolpaths.​​​​​​​
    SUBMIT
  • Laser Cutting & Marking
    Clean, burr-free cuts for blade edges; permanent laser marking (logos/IDs) resistant to 96-hour salt spray and repeated sterilization.​​​​​​​
    SUBMIT
  • Surface Treatment
    Passivation (316L stainless steel) for corrosion resistance; mirror polishing (Ra 0.02μm) for blood-contacting components (e.g., heart pump impellers).​​​​​​​
    SUBMIT
  • Heat Treatment​​​​​​​
    Controlled hardening for 4Cr13 scissors (HRC 50-58) to balance sharpness and toughness; stress relief for 3Cr13 forceps to prevent fatigue failure.​​​​​​​

Why Choose Us

 
Medical-Grade Expertise: Custom Solutions, Precision & Quality You Can Trust

Project Expert Team

 
  Our team averages 10+ years of specialized experience in medical component machining—equipped with top-tier 5-axis CNC centers and precision lathes. We handle complexities unique to medical devices: from thin-walled surgical instrument housings (0.05mm wall thickness) to intricate robotic end-effectors, achieving micrometer-level precision (±0.002mm) critical for patient safety and device performance.
 

Customized Solutions

 
We tailor every step to your medical project’s needs: from design optimization (e.g., reducing implant component deformation) to scalable manufacturing. Whether prototyping a new laparoscopic tool or ramping to mass production of surgical scissors, we align with regulatory timelines (FDA/CE submissions) and flexibly adjust processes to accelerate your medical device launch—without compromising compliance.
 

Strict Quality Control

 
Our medical-grade QC process spans the entire lifecycle:   Incoming inspection of biocompatible materials (316L stainless steel, titanium, PEEK) with full traceability (ISO 13485-compliant documentation).   In-process checks for critical features (e.g., blade edge continuity, implant surface smoothness).   Final validation via advanced testing (biocompatibility screening, 96-hour salt spray resistance) to ensure reliability in clinical use.
 

Precision Inspection

 
We leverage industry-leading tools—Zeiss & Hexagon CMMs, Marr optical comparators, and Mitsutoyo precision gauges—to verify tight tolerances (geometric tolerances ≤0.02mm) and surface finishes (Ra ≤0.02μm) for medical components. With a 99.5% pass rate, our inspection data supports your regulatory submissions and guarantees consistent performance in surgical and implantable devices.
 

Materials & Surface Treatments

Materials & Treatments for Surgical Performance
  • Metals


     420 stainless steel (scissors/forceps) for sharpness; 316L (implant tools) for corrosion resistance; titanium alloy (neuro surgical tools) for lightweight strength.

  • Polymers

FAQs

Q1: What materials do you use for surgical instruments, and how do you ensure biocompatibility?

A: We specialize in medical-grade materials tailored to instrument functionality: 420/316L stainless steel (for scissors, forceps) for corrosion resistance and sterilization durability; titanium alloys (for neuro/orthopedic tools) for lightweight strength; and PEEK (for robotic components) for biocompatibility. All materials come with full traceability (certified by suppliers like Fushun Special Steel) and undergo biocompatibility testing (USP Class VI, cytotoxicity screening) to meet ISO 13485 and FDA requirements.

Q2: How do you prevent laser marking fading or rusting on medical devices during salt spray tests?

A: Our laser marking process combines two key steps to ensure durability: 
① Pre-marking surface preparation (plasma cleaning to remove contaminants) for better adhesion; 
② Post-marking passivation or vacuum plasma coating (for metal components) to seal the marked area. We validate with 96-hour salt spray tests, ensuring no fading, rust, or discoloration—critical for long-term instrument identification and corrosion resistance.

Q3: What quality inspections do you perform on critical surgical components, like thin-walled parts or blade edges?

A: For critical components, we implement 10+ inspection checks, including:
 ① Dimensional accuracy (via CMM, with tolerances as tight as ±0.002mm for thin-walled parts like 0.05mm lens holders); 
② Surface quality (50-100x magnification to check for burrs/scratches on blade edges, ensuring no gaps or rollover); 
③ Mechanical performance (blade sharpness testing under microscopy, 10,000-cycle durability tests for hinges). All inspections are documented with first-article and in-process reports, ensuring full traceability for regulatory submissions.
