Our material experts can help you select the optimal material based on your application’s environmental conditions, load requirements, and budget constraints. We also offer various surface treatments including passivation, electroplating, and powder coating to enhance spring performance and appearance.
Custom Spring Design & Engineering Support
As a leading custom compression spring manufacturer, we understand that every application has unique requirements. Our engineering team works closely with clients to develop springs that perfectly match their specifications:
Design Parameters We Consider:
- Spring rate (load per unit deflection)
- Free length and solid height
- Wire diameter and outer diameter
- Number of active coils
- End type (closed, open, ground)
- Material selection based on environmental factors
- Surface finish requirements
- Fatigue life expectations
We utilize advanced CAD software and finite element analysis (FEA) to simulate spring performance under various conditions before production begins. This ensures your springs will perform reliably in real-world applications.
Prototyping & Sample Production
For complex projects or new designs, we offer rapid prototyping services to validate your spring design before full-scale production. Our CNC machines can produce sample springs within days, allowing for quick testing and design iterations if needed.
