The piston rod of the NG-SHM Class DP – Servo Hydraulic Testing Machine is plated with Nickel and Chrome, with a coating thickness up to 0.1 mm. This plating serves two key purposes: it protects the piston rod from corrosion and significantly reduces wear during operation. By preventing corrosion, plating helps maintain the mechanical strength and surface quality of the rod, which is critical for maintaining accurate and consistent performance over time.

In addition, the reduced wear from this protective layer extends the piston rod’s lifespan, minimizing maintenance needs and avoiding unexpected downtime. This is especially important in high-force mechanical testing, where the piston is subjected to intense stress and movement. The smooth, plated surface also improves sealing function, supporting better hydraulic pressure control and overall system efficiency.
