Products
We supply full-category shock absorber components, including pistons, stampings, rubber seals, piston rods, springs, and self-developed banding/grooving machines.
Lightweight Formed Metal parts
Lightweight Formed Metal parts from XIAYI split the job three ways: an ST14 base, an ST13 dish shim alive through one million elastic cycles, and an ST12 hollow plate that drains water while cutting weight. Your supplier ships the set factory-matched for automatic lines.
The Lightweight Formed Metal Parts kit is a three-layer composite: a raised cylindrical base, a concave dish-shaped elastic buffer shim, and a hollow flow-diversion locating plate. Each layer uses a different steel — ST14 for strength, ST13 for elasticity, ST12 for lightness — because one material can never be right for three different jobs. The hollow plate adds drainage and anti-slip while cutting weight.
What Each Layer Does
| Layer | Substrate | Function |
|---|---|---|
| Raised cylindrical base | ST14 deep-drawing steel | Wraps the buffer rubber's outer ring, restricting radial expansion; wide flange disperses vibration load |
| Dish-shaped buffer shim | ST13 soft stamped steel | Absorbs impact through tiny elastic dish deformation — flexible shock absorption, no sharp-corner cutting |
| Hollow flow-diversion plate | ST12 cold-rolled steel | Three arc long holes drain water vapor and silt; hollow ribs form three-point bite limit — and cut weight |
Independent Line for Each Layer
- Separate coil bins & spectrum tests — ST14/ST13/ST12 never mixed, each leveled and verified independently
- Own forming station per part — 6-station drawing for the base, 4-station arc stamping for the shim, 3-station hollow punching for the plate
- Unified composite aging — all three semi-finished layers heat-treated together at 120 ℃ for 4 h to kill springback
- Synchronous deburring & matched plating — three layers stacked and cleaned together, zinc-plated on the same fixture for uniform coating
- 3D coordinate paired inspection — the system auto-matches full-set dimensions and rejects missing or mismatched parts
Layer-by-Layer Durability Proof
| Layer | Verified Result |
|---|---|
| Cylinder base (ST14) | No wall collapse after million-cycle lateral vibration; no pitting after salt spray testing |
| Dish shim (ST13) | No fatigue crack after 1,000,000 reciprocating elastic-deformation cycles — elasticity retained |
| Hollow plate (ST12) | Three-point bite ribs unworn, diversion holes unblocked for long service |
| Composite kit | No dimensional drift after 1000 hot-cold cycles (−40 ℃ to +110 ℃); abnormal-noise failure rate down 75% |
FAQ
Q: Why three different steels instead of one strong grade throughout?
A: Because the jobs differ: the base needs fatigue strength, the shim needs elastic rebound, and the plate needs lightness at low cost. Matching substrate to function keeps every layer durable — hard steel in the shim would just transmit noise.
Q: Our sealed kits trap water and rot the rubber. Does the hollow plate help?
A: Yes — the three arc long holes drain water vapor and silt automatically, so the rubber never soaks. That drainage is also why the bite ribs stay functional for the life of the part.

Ningbo XiaYi Electromechanical Tech Co., Ltd. supplies layer-matched composite kits with unified dimensions for automatic assembly. Send your rubber geometry for a set proposal.
About XIAYI layered engineering: the ST14/ST13/ST12 assignment is not a cost trick — each layer was tested in its own duty cycle, and the composite set is assembled from three validated parts, not three guesses.
