Frequently Asked Questions (FAQ)
Q1: What materials are used for rust-proof springs?
A: We offer stainless steel (304, 316, 316L), spring steel with various anti-corrosion coatings (zinc plating, epoxy, PTFE, Dacromet), and other alloys. For 100% corrosion resistance in harsh environments, stainless steel is recommended. We can also customize based on your specific chemical exposure.
Q2: How do I request a free sample?
A: Simply contact us with your requirements (dimensions, load, material, quantity). We will provide a sample quotation. For small samples, we may offer them free of charge with the buyer covering shipping, or we can include the sample cost in a future order. Please discuss with our sales team.
Q3: Can you make springs with non-standard sizes and shapes?
A: Absolutely. Custom sizes are our specialty. We can work from your drawings, CAD files, or even a physical sample. Our engineers will review and produce springs that match your exact specifications.
Q4: How do you ensure the corrosion resistance of the springs?
A: We use high-quality raw materials and apply proven surface treatments. For stainless steel springs, the material itself provides inherent corrosion resistance. For coated springs, we perform salt spray tests (NSS) to verify performance. Each batch is inspected for coating thickness and uniformity.
Q5: What is the typical lead time?
A: Standard custom springs: 15–25 working days after confirmation. For urgent orders, we can expedite to 10–15 days. Free samples are usually shipped within 5–7 days.
Q6: Do you have any certifications?
A: We have internal quality control systems and can provide material test reports, dimensional inspection reports, and salt spray test reports upon request. Specific certifications (e.g., ISO) can be arranged if required; please inquire with our sales team.
Q7: What is the minimum order quantity (MOQ)?
A: For standard sizes, MOQ is typically 1000 pieces. For custom designs, MOQ may be lower depending on complexity and production setup. We are flexible and welcome small trial orders.
Q8: How do you package the springs for shipping?
A: We use anti-rust paper, plastic bags, and cartons or wooden crates depending on the size and weight. For export, we ensure packaging is suitable for long-distance sea or air freight to prevent damage and corrosion.
