Our SUS304 cylindrical helical compression spring is precision manufactured by CNC spring coiling machine. This stainless steel coil spring adopts closed unground ends design without end grinding. It goes through stress relief tempering to eliminate internal coiling stress for stable elasticity. Surface treatment is clean bright polished finish without extra plating or coating, relying on natural anti-corrosion property of SUS304 stainless steel.
We are a professional custom compression spring manufacturer offering OEM custom service. We can produce custom compression springs according to your technical drawings or physical samples. The spring has smooth surface after deburring and cleaning, suitable for many light load elastic reset applications.

We provide full custom & OEM service for compression springs. You can send us 2D/3D drawings or physical samples for custom spring development. We support custom wire diameter, outer diameter, free length, coil quantity, end type and surface finish. Our engineering team reviews your requirements and provides technical suggestion for custom compression spring projects. Small batch and mass production are both acceptable.
- Stable elasticity: Stress relief tempering removes internal coiling stress to prevent early fatigue and deformation.
- Natural corrosion resistance: SUS304 material avoids extra coating peeling issue.
- Smooth clean surface: Deburring & bright polishing prevent scratch damage to mating parts.
- Flexible custom OEM: Adjust dimensions and parameters to match your equipment assembly requirements.
- Consistent precision: CNC coiling ensures dimension repeatability for batch production.
Raw SUS304 material inspection before production. In-line dimension checking during CNC coiling process. Elastic performance sampling test after tempering. Final visual inspection for surface defect and deburring verification before packing. All springs follow standard spring manufacturing specifications, custom inspection criteria acceptable for OEM orders.
Sample orders can be delivered within 3–7 working days after drawing confirmation. Mass production lead time depends on order quantity. We support multiple shipping methods including air express and sea freight. We pack springs carefully to avoid deformation during transit. Worldwide shipping available for international clients.
