Functions of Shock Absorber Part
Shock absorber piston moves up and down inside the shock absorber cylinder, forcing hydraulic fluid slowly through precisely designed small valves to provide resistance to slow down the spring movement.
Shock absorber guide supports the piston rod, ensuring its precise alignment within the shock absorber.
Shock absorber valves control fluid flow during compression and rebound to adjust suspension resistance.
PM Shock Absorber Parts Benefits
Shock absorber parts are pressed with iron-based metal powder as raw materials, with high material utilization.
Powder metallurgy allows shock absorber components to achieve strict dimensional tolerances, precise part matching, and reliable shock absorption performance.
PM shock absorber parts can be impregnated with oil to provide a self-lubricating effect, extending their service life.
With precise control of the powder metallurgy process, shock absorber parts offer excellent quality consistency.

A shock absorber valve is the part of a shock absorber that controls the flow of hydraulic fluid between its chambers.
FAQ's
Here are some of the questions we get asked often. If yours isn’t answered, don’t hesitate to contact us, we’re happy to help!
A car shock absorber is a component of the vehicle’s suspension system that absorbs and dampens shock impulses from the road surface, enhancing driving comfort and vehicle handling.
The pistons, guides, and valves within the shock absorber are often made using powder metallurgy, which provides high dimensional accuracy and cost-effectiveness in production.
Shock absorbers are usually composed of the following key parts:
- Piston
- Piston Rod
- Cylinder
- Valves
- Guides
- Oil Seals
- Bushings
- Spring
These components work together to absorb and dampen shock impulses, enhancing driving comfort and vehicle handling.
