Hydraulic optimization tips
🔹 Anti-cavitation design： thread fluid dynamics optimization
🔹 Quick response： < 20 minutes to switch the mold, support small batch multi-species
🔹 Intelligent prediction： recommendation of optimal preload torque based on pressure data
Parameters | Conventional turning | Cold heading process |
Cost | ￥8.6 per piece | ￥4.2 per piece |
Production rate | 120 pieces per hour | 800 pieces per hour |
Life expectancy | 2 years | 5 years |
The process breakthrough of cartridge valve screw cost reduced by 50%
Cold heading instead of turning, surface carbon tungsten coating instead of hard chromium plating, strength and corrosion resistance double

Build Your Custom Solution in 3 Steps
1. Select Your Groove Type – Optimize for Strength or Flexibility
Choose from 10+ engineered groove profiles – from standard V-grooves for general applications to specialized T-slots for heavy machinery.
Our CNC machining ensures ±0.005mm tolerance for perfect load distribution.
Pro Tip: 90% of industrial clients select helical grooves for vibration resistance.
2. Choose Tooth Type: Precision Cutting or Smooth Engagement
Select triangular teeth for high-speed cutting (ideal for aerospace alloys)or rounded teeth to reduce wear in repetitive assembly (common in automotive).
Custom tooth pitch options available – Our engineers recommend 2.5mm pitch for 80% of polymer applications.
3. Design Your Head Shape: Functional Aesthetics Meets Installation Efficiency
From low-profile hex heads (ISO 4762) to tamper-resistant Torx designs, select shapes that align with your tooling ecosystem.
Pro Tip: 70% of clients pairing button heads with recessed grooves reduce installation time by 40%.
Precision-engineered from concept to delivery: Streamlined 5-stage process with 1-hour response, 72h prototyping, and ISO-certified quality control.
