Our hydraulic cylinders, built for construction equipment, are engineered to be rugged and exceptionally reliable. Withstand heavy-duty applications in challenging environments, reducing the risk of costly downtime, project delays, and maintenance issues.
Refined Production Process:
From raw materials feeling to tempering, we proceed with precision: cylindrical lathe cutting, high-frequency quenching, cylindrical grinding, hard chrome plating, and finally, external grinding, ensuring top-tier performance.
Post-tempering and high-frequency quenching, the external surface undergoes hard chrome plating for superior durability.
This meticulous process ensures the surfaces are both internally and externally hardened and smoothed, enhancing longevity and efficiency.
