Direct answer: Zhengna Technology manufactures custom compression springs for OEM applications where load, deflection, material, fatigue risk, and batch repeatability must be controlled from sampling to production.
| Buyer check | Why it matters |
|---|---|
| Material and wire diameter | Controls load, fatigue life, corrosion resistance, and forming stability. |
| Load points and working range | Confirms the spring performs in the real installed condition. |
| Heat treatment or stress relief | Stabilizes force, dimensions, and fatigue behavior after forming. |
| Surface treatment | Matches corrosion, appearance, and assembly environment requirements. |
| Inspection and packaging | Protects traceability, load consistency, and deformation-free shipment. |
Provide wire diameter, outer diameter, free length, load at height, material, finish, quantity, and operating environment.
Yes. Zhengna Technology can inspect dimensions and load points according to buyer drawings and functional requirements.
Material, stress level, working stroke, surface condition, heat treatment, environment, and production stability all affect fatigue life.
