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:
Precision CNC Cutting
High-strength steel plates are laser-cut with CNC machines to
ensure accuracy and consistent material strength.
Welding & Assembly
Experienced technicians perform precision welding on cylinder
barrels, bases, and heads using automatic welding stations.
Heat Treatment
All core components undergo high-temperature quenching to improve
hardness and wear resistance.
CNC Machining
Cylinder rods are machined and threaded using CNC lathes to ensure
perfect alignment and smooth operation.
Polishing & Chrome Plating
The rod surfaces are finely polished and hard chrome plated for
corrosion resistance and extended service life.
Grinding & Honing
Inner cylinder walls are honed to precise tolerances to ensure
smooth piston movement and pressure sealing.
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.
