Key Points Keep The High Quality
| 1) Raw matrail . |
| Thickness less than 20mm. we choose SUP9/55Cr3/SAE5160H as the product material |
| Thickness from 20-30mm. wE choose SUP11A/50CrVA |
| Thickness more than 30mm. We choose 51CrV4 as the raw material |
| Thickness more than 50mm. We choose 52CrMoV4 as the raw material |
| 2) Quchenging Process |
| We strickly controled the steel temeprure around 800 degree. |
| we swing the spring in the qenching oil among 10 seconds according to the spring thickness. |
| 3)Shot Peening. |
| Each assmembing spring set under stress peening . |
| Fatigue test can reach over 150000 cycus |
| 4) Painting |
| Each leaf under cataphoresis painting. |
| Salt spray testing reach 500hours |
