Springs FAQ Common Questions
Q: How do I choose the right spring for my application?
A: Consider these factors: load requirements (compression/torsion/tension), environmental conditions (temperature, corrosion), space limitations, and cycle life expectations. Our engineers can help select the optimal spring configuration based on your specific needs.
Q: What maintenance do springs typically require?
A: Most springs require minimal maintenance when properly specified. For harsh environments, consider protective coatings or regular lubrication. Inspect springs periodically for signs of fatigue, corrosion, or deformation - especially in critical applications.
Q: Can you manufacture custom spring designs?
A: Yes, our facility specializes in custom spring solutions. We can produce springs to your exact specifications regarding dimensions, materials, coatings, and performance characteristics. Submit your drawings or requirements for a quote.

| Music Wire (ASTM A228) | 2000-2300 MPa | Good (with coating) | -40°C to 120°C | Precision instruments, mechanical components |
| Phosphor Bronze | 600-900 MPa | Excellent | -60°C to 150°C | Electrical contacts, marine hardware |
Springs FAQ Common Questions (Continued)
Q: How does spring wire diameter affect performance?
A: Wire diameter directly impacts spring characteristics. Thicker wire provides greater load capacity but reduces deflection. Thinner wire allows for more flexibility but has lower load ratings. We calculate optimal wire diameter based on your required spring rate and space constraints.
Q: What's the lead time for standard spring orders?
A: Standard springs typically ship within 2-3 weeks. Expedited options are available for urgent requirements. Custom designs may require 3-6 weeks depending on complexity. Contact us for exact timelines based on your order specifications.
Q: How do you ensure consistent spring quality?
A: Our quality assurance process includes material certification, dimensional verification, load testing, and surface inspection. We use automated optical measurement systems and statistical process control to maintain tight tolerances (typically ±5% for spring rate).
Surface Treatment Options
- Electroplating: Zinc, nickel, chrome for corrosion resistance
- Passivation: For stainless steel to enhance corrosion resistance
- Powder Coating: For color coding and additional protection
- Oxide Coating: Black oxide for aesthetic and mild protection
Springs FAQ Common Questions (Final Section)
Q: What's the difference between active and inactive coils?
A: Active coils participate in spring deflection under load, while inactive coils (typically at the ends) provide mounting surfaces. The number of active coils affects spring rate - more active coils create a softer spring. Our designs optimize this balance for your application requirements.
Q: Can springs be designed for constant force applications?
A> Yes, special constant force springs maintain nearly uniform force throughout their deflection range. These use a unique spiral-wound design rather than traditional coil configurations, ideal for applications like retractable cords or counterbalance systems.
Q: What documentation do you provide with spring shipments?
A> All orders include material certifications, inspection reports, and dimensional data. For custom springs, we provide comprehensive engineering drawings and performance test data. Additional documentation like PPAP or IMDS reports available upon request.
