Frequently Asked Questions (FAQ)
-
Q: What is the minimum order quantity (MOQ) for custom coil springs?
A: We accept small orders for prototypes, often starting from 100 pieces. For large-scale production, MOQ can be negotiated based on wire diameter and complexity. -
Q: Do you test the springs before shipping?
A: Yes, we perform dimensional inspection, load testing (force vs. deflection), and surface finish checks. Samples can be sent for approval before mass production. -
Q: Can you replicate an existing spring? Do you need a drawing?
A: Yes, we can reverse-engineer from a sample. We recommend providing a drawing or detailed specifications (wire diameter, OD, free length, number of coils, material). If no drawing, we can create one for your approval. -
Q: What materials are available for custom coil springs?
A: We offer stainless steel (304, 316, 17-7PH), carbon steel (SAE 1070, 1095), alloy steel (chrome silicon, chrome vanadium), music wire, beryllium copper, and Inconel. Other materials are available upon request. -
Q: How long does it take to manufacture a custom spring?
A: Typically 7–15 working days for standard custom springs with simple dimensions. Complex designs or large quantities may require 20–25 days. Rush orders are available. -
Q: What is the warranty coverage for the springs?
A: We offer a 1-year warranty against manufacturing defects such as breakage due to material flaws or improper coiling. Normal wear and tear or misuse are not covered. -
Q: Do you provide free samples?
A: We can provide samples for evaluation; however, the customer usually pays for shipping. For bulk orders, the sample cost may be waived. -
Q: How do I ensure the spring will fit my application?
A: Provide us with your working environment, load requirements, and space constraints. Our engineers can recommend the optimal spring design and provide a technical drawing for your approval.
