Applications and Characteristics of Special-shaped Pins in the Medical Industry
How Our Machining & Cold Heading Processes Solve Practical Problems
Specific Product Applications in Medical Industry
Life Support & Monitoring Equipment
  • Neonatal incubators & infant warmers: Positioning pins, limit pins, hinge pins for door panels, support brackets, and adjustment mechanisms.
  • Anesthesia machines & ventilators: Special-shaped locking pins, positioning pins for gas circuit modules, control panels, and internal structural components.
  • Patient monitors & portable ultrasound devices: Anti-rotation special pins for internal supports, component fixing, and module assembly.
Surgical Instruments & Minimally Invasive Devices
  • Laparoscopic / endoscopic instruments: Special-shaped drive pins, limit pins, and connecting pins for handle assemblies, bending sections, and actuating mechanisms.
  • Orthopedic & dental instruments: Special locking pins, stepped pins, and knurled positioning pins for surgical drills, handpieces, and implant tools.
  • Surgical robot arms: High-precision special-shaped pivot pins, joint pins, and transmission pins for small-space, high-load motion structures.
Diagnostic & Laboratory Equipment
  • Biochemical analyzers & hematology analyzers: Special drive pins, eccentric pins, and guide pins for sampling mechanisms, reagent trays, and pump assemblies.
  • CT / MRI equipment: Non-magnetic special-shaped pins for internal shielding, platform positioning, and non-interference motion systems.
Rehabilitation & Assistive Devices
  • Rehabilitation robots & exoskeletons: Special joint pins, stepped pins, and anti-falling pins for limb movement structures.
  • Orthopedic braces & prosthetics: Biocompatible special-shaped positioning pins and fixing pins for adjustable support components.
Key Characteristics of Medical-grade Special-shaped Pins
  • High precision & complex geometry: Can realize stepped, knurled, eccentric, flanged, grooved, and other non-standard shapes.
  • Stable fitting & anti‑rotation / anti‑loosening: Special structural design ensures no displacement under vibration and repeated assembly.
  • Medical materials & biocompatibility: Mainly 316/316L stainless steel, titanium alloy, meeting ISO 10993 requirements.
  • Sterilization resistance: Resistant to autoclaving, EO, and alcohol disinfection without corrosion or precipitation.
  • Hygienic design: Smooth surface, no dead angles, easy cleaning, suitable for medical-grade cleanliness.
  • High strength & long service life: Stable performance under high-frequency movement and long-term use.
Practical Problems Solved by Our Machining & Cold Heading Processes
High precision for complex special shapes
  • Cold heading for high-efficiency near-net-shape forming.
  • Precision machining for tight tolerances, ensuring stable assembly and interchangeability.
Consistency & stability in mass production
  • Cold heading provides stable dimension, grain structure, and mechanical performance.
  • Reduces deformation and improves reliability in medical equipment.
Cost reduction for medical components
  • Combined cold heading + machining reduces material waste and processing time.
  • Improves cost efficiency without compromising medical-grade quality.
Surface quality & cleanliness
  • Supports polishing, passivation, electropolishing for Ra ≤ 0.8 μm.
  • Free of burrs, cracks, and contamination risks.
Customization for medical devices
  • Flexible development for non-standard pins according to assembly space, motion mode, and load.
  • One-stop solution from design to mass production.
