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, and achieves 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
