Hydraulic cylinders for construction equipment must epitomize durability and reliability, enduring extensive use in challenging environments. Any service failure translates into costly downtime, project interruptions, and maintenance challenges.
Production Process Overview:
The production journey includes: Material selection → Precision tempering → Cylindrical lathe operations → High-frequency quenching → Cylindrical grinding → Hard chrome plating → External surface grinding.
Post-tempering, coupled with surface high-frequency quenching, our products receive an external hard chrome finish.
This process ensures a robust internal and external structure, accompanied by a flawlessly smooth surface.
