Heat treatment of Hollow piston rod

Quenching and QPQ nitriding of hollow piston rods are key steps to improve their performance:

Quenching: Rapid cooling increases surface hardness and enhances wear resistance.

QPQ nitriding: During the nitriding process, a hard nitriding layer is formed on the surface, further improving Hollow piston rod wear resistance and corrosion resistance

Application of Hollow hydraulic rod and QPQ nitriding technology in the furniture industry:

1、 In the lifting mechanism of office chairs, hollow piston rods provide stable support and smooth movement, while QPQ treatment ensures durability for long-term use.

2、In the adjustment mechanism of beds, hollow piston rods are used to adjust the height of the head and foot of the bed, while QPQ treatment ensures the reliability of these components in daily use.

3、In the lifting door and drawer system of cabinets, hollow piston rods are used to provide cushioning and support, while QPQ treatment enhances the corrosion resistance of these components.
