Frequently Asked Questions

What is a volute spring and how is it different from a regular coil spring?
A volute spring (also called conical spring) has a tapered profile where the coil diameter gradually decreases from one end to the other. This design allows for a compact compressed height and provides progressive spring rate, ideal for applications where space is limited.
Can you supply springs with thickness outside the 0.5-2mm range?
Yes, we can customize springs with thicker or thinner wire diameters upon request. Please contact us with your specific requirements.
What materials are available for these springs?
Standard materials include high-carbon spring steel (e.g., 60Si2MnA) and alloy spring steel (e.g., 50CrVA). Stainless steel (e.g., 304, 316) and other materials are also available for special environments.
How do you ensure the tempering process is consistent?
We use a 220V electric tempering furnace with precise temperature control (±5°C). Each batch is monitored and recorded to guarantee uniform heat treatment.
Do you provide test reports or certificates?
Yes, we can provide material test reports, dimensional inspection reports, and load testing data. Certificates of compliance are available upon request.
What is the typical lead time for custom volute springs?
For standard sizes, lead time is 7-15 working days. Custom orders may require 15-30 working days depending on complexity and quantity.
What packaging options do you offer for export?
We offer standard carton packaging, wooden cases, or pallet packaging to protect springs during transit. Custom packaging can be arranged.
Can you supply springs that meet specific international standards?
Absolutely. We can manufacture springs according to DIN, JIS, GB, and other customer-defined standards. Our production process is flexible to meet your compliance requirements.
