‌ 5 Key Steps to Premium Carbide Tips ‌

1. ‌ Smart Material Mix ‌

   • Uses ‌ imported tungsten carbide (90%+ purity) ‌ and ‌ high-cobalt alloys (7-12% Co) ‌
   • Custom recipes for different rocks (100,000+ geological profiles)

2. ‌ Precision Pressing ‌

   • Special pyramid shape cuts faster
   • Hydraulic presses apply 300+ MPa pressure

3. ‌ Density-Boost Sintering ‌

   • 1,400°C heat + 100 MPa pressure
   • Reduces air gaps to <0.2%

4. ‌ Laser-Sharp Finishing ‌

   • Accuracy: ±0.008 mm (hair-thin precision)
   • Smooth surface prevents tip loss

5. ‌ Robot-Assembly ‌

   • Automated welding at 800°C (±5°C)
   • X-ray checks every joint
