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.

    Warehouse

    We operate a well-organized warehouse with a large inventory of excavator hydraulic parts, including cylinders, pumps, valves, and seals.
    With ample stock and efficient logistics, we ensure fast delivery to meet urgent orders and global demand.
