Product Description

Resistant to High Temperature Steam Sterilization Tungsten Carbide Processing Customized for Medical Instruments
Resistant to High Temperature Steam Sterilization Tungsten Carbide Processing for Medical Instruments
The precision punch with 94% tungsten carbide matrix (YG6X Grade) and nanometer-level edge passivation (R0.02mm) breaks through the burr and delamination bottleneck of traditional SKH51 high-speed steel, achieving perfect cutting with cross-section finish Ra ≤0.8μm in the cutting of carbon fiber/glass fiber/aramid composite tubes.
Tech-breakthrough
  • Matrix material: 94% WC + 6% Co submicron sintering (grain size 0.5μm)
  • Edge design:
    • Two-stage shear angle (15° main edge + 3° micro flat edge)
    • Edge electrolytic passivation R0.02mm (anti-crack ↑400%)
  • Surface engineering:
    • Mirror polishing Ra≤0.05μm (resin adhesion ↓95%)
    • Multi-layer DLC coating (friction coefficient 0.06)
  • Thermal management:
    • Embedded copper core heat pipe (operating temperature ≤80℃)
    • Thermal expansion coefficient matches carbon fiber (2.5*10⁻⁶/K)
Applications
Medical life channel
  • Vascular intervention catheter: cutting burr height ≤ 3μm (to prevent thrombosis risk)
  • Laparoscopic instrument tube: resistant to high temperature steam sterilization (＞134℃)
  • Ventilator bellows: aramid fiber fuzz-free cutting
Car core pipeline
  • Turbocharger oil pipe: glass fiber reinforced nylon anti-explosion cutting
  • Brake system pipeline: carbon fiber/metal composite pipe without cracking
  • Fuel cell hydrogen pipe: chemical corrosion resistant cutting
High-end industrial transmission
  • Industrial robot cable protection tube: anti-abrasive wear
  • Optical cable reinforced core aramid tube: 0.1mm thin wall without deformation
  • Aviation hydraulic Teflon tube: anti-adhesion continuous production
