Hydraulic Cylinder Manufacturing Process

Our factory operates with advanced semi-automatic production lines and strict quality control to ensure each hydraulic cylinder meets OEM standards. The production process includes:

1. Precision CNC Cutting
   High-strength steel plates are laser-cut with CNC machines to ensure accuracy and consistent material strength.

2. Welding & Assembly
   Experienced technicians perform precision welding on cylinder barrels, bases, and heads using automatic welding stations.

3. Heat Treatment
   All core components undergo high-temperature quenching to improve hardness and wear resistance.

4. CNC Machining
   Cylinder rods are machined and threaded using CNC lathes to ensure perfect alignment and smooth operation.

5. Polishing & Chrome Plating
   The rod surfaces are finely polished and hard chrome plated for corrosion resistance and extended service life.

6. Grinding & Honing
   Inner cylinder walls are honed to precise tolerances to ensure smooth piston movement and pressure sealing.

7. Assembly & Testing
   All parts are assembled in dust-free environments. Each cylinder undergoes 100% pressure testing to detect leakage, stroke deviation, and performance under load.
