Product Process
1. Material Cutting & Preparation
We start with high-strength steel plates. CNC cutting ensures every piece has exact dimensions and consistent strength.
2. Welding and Component Integration
Barrels, end caps, and mounting bases are welded with precision. Automated welding and skilled hands work together for a strong, lasting structure.
3. Heat Hardening Process
Key parts go through controlled quenching and tempering. This boosts hardness and improves wear resistance.
4. Precision CNC Machining
Rods are turned, threaded, and finished on advanced CNC lathes. The result is perfect alignment and smooth operation under pressure.
5. Surface Finishing & Plating
Each rod is polished in several steps, then hard chrome plated. This protects against corrosion and extends service life.
6. Bore Honing
The inside of each barrel is honed to tight tolerances. This ensures smooth piston travel and a perfect hydraulic seal.
7. Final Assembly & Performance Verification
All parts are assembled in a clean workspace. Every cylinder is fully pressure-tested for leaks, stroke accuracy, and performance under load.
