Hydraulic cylinders utilized in construction equipment must embody robustness and dependability. These components endure strenuous usage in challenging environments, and any service failure could lead to costly downtime, project setbacks, and maintenance hurdles.
Production Process:
The meticulous production process includes: Material feeling → Tempering → Cylindrical lathe cutting → High-frequency quenching → Cylindrical grinding → Hard chrome plating → External grinding, ensuring high-quality output.
The external surface undergoes hard chrome plating after tempering and surface high-frequency quenching,
making it durable internally and externally, complemented by a smooth finish.
