What types of custom precision springs do you manufacture?
We specialize in manufacturing a wide variety of precision metal springs, including compression springs, extension springs, torsion springs, wire forms, and helical antenna springs. We also provide precision CNC machined parts to offer comprehensive hardware solutions for our global B2B clients.
What is your manufacturing capability regarding spring wire diameter?
We are equipped with advanced CNC coiling machinery that allows us to manufacture springs with extremely tight tolerances. Our wire diameter capabilities range from ultra-fine 0.03mm micro-springs up to heavy-duty 16mm industrial springs.
Do you specialize in micro-springs for electronic components?
Yes, manufacturing electronic micro-springs is one of our core competencies. We design and produce highly precise, small wire-diameter springs specifically engineered for switches, connectors, sensors, and other critical electronic assemblies.
Can you manufacture springs based on custom CAD drawings or OEM samples?
Absolutely. With over 20 years of expertise in hardware manufacturing, our engineering team excels at translating custom CAD designs or physical samples into high-performance mass-produced parts.
Do you provide engineering support or spring design optimization?
Yes. If you are experiencing issues like spring buckling, fatigue failure, or spatial constraints, our technical team can review your specifications and recommend optimizations in spring index, pitch, or material to ensure optimal performance.
What materials do you commonly use for custom spring production?
We source premium-grade raw materials to ensure durability. Our common materials include Stainless Steel (such as 304 and 631), Phosphor Bronze, Beryllium Copper, Carbon Steel, and Music Wire, depending on your application's requirements.
Why is Beryllium Copper or Phosphor Bronze often used in your electronic springs?
These materials are highly sought after in the electronics industry due to their excellent electrical conductivity, superior fatigue strength, and reliable corrosion resistance, making them ideal for battery contacts and antenna springs.
How do I choose the right stainless steel grade for my application?
For general corrosion resistance, 304 stainless steel is an excellent standard choice. If your application requires higher tensile strength and heat resistance, 631 (17-7 PH) stainless steel is highly recommended. Our engineers can guide you based on your operating environment.
What surface treatments do you offer for metal springs?
To enhance longevity, corrosion resistance, and aesthetics, we offer a variety of surface treatments including zinc plating, nickel plating, gold/silver plating (often used for electronic contacts), passivation, and black oxide.
What quality control standards do you follow during production?
We adhere to strict quality management systems throughout the entire manufacturing process. From raw material inspection to first-article approval and final shipment testing, we ensure every batch meets precise international B2B standards.
How do you ensure precision in ultra-fine 0.03mm micro-springs?
Manufacturing at the 0.03mm scale requires exceptional technical mastery. We utilize state-of-the-art multi-axis CNC spring coiling machines and optical inspection equipment to maintain strict dimensional tolerances and consistent load profiles.
How do you test the fatigue life and load capacity of your springs?
We utilize advanced force testing equipment and fatigue cycle testers to verify that the spring rate and maximum load capacity precisely match your engineering specifications, ensuring long-term reliability.
Can you provide material certificates and inspection reports?
Yes. For full traceability and compliance, we can provide material certifications (mill test reports) and detailed dimensional inspection reports with your shipments upon request.
What information do I need to provide to get an accurate quote?
To provide a fast and precise quotation, please share your 2D/3D drawings or the following details: wire diameter, outer/inner diameter, free length, number of active coils, material grade, surface treatment, and required order quantity.
What is your Minimum Order Quantity (MOQ) for custom springs?
We understand that B2B projects require flexibility. While we have massive production capabilities for large-volume orders, we also accommodate lower MOQs for prototyping and initial product testing. Contact our sales team to discuss your specific volume needs.
What is your typical lead time for prototypes and mass production?
Lead times depend on the complexity and volume of the order. Generally, prototypes and sample orders can be completed quickly, while mass production lead times are highly competitive. We prioritize efficient scheduling to meet your project deadlines.
Do you have experience exporting products internationally?
Yes, we have extensive experience serving international B2B clients across various regions. We are familiar with global shipping logistics, international trade terms (Incoterms), and export documentation.
How do you package delicate micro-springs to prevent tangling during transit?
Tangling is a common issue with small wire-diameter springs. We use specialized packaging solutions such as custom blister trays, adhesive boards, or PE bags with precise oiling to ensure your micro-springs arrive perfectly separated and ready for automated assembly lines.
Can you handle custom packaging requirements?
Yes, we can accommodate custom packaging requests, including barcoding, specific labeling, and standardized carton sizes to seamlessly integrate into your inventory management system.
What shipping methods do you offer for international buyers?
We offer flexible shipping options based on your urgency and budget, including express air freight (DHL, FedEx, UPS) for urgent components and cost-effective sea freight for high-volume mass production orders.
How do you resolve issues if a product does not meet specifications?
We pride ourselves on long-term partnerships. In the rare event of a discrepancy, our after-sales team will quickly investigate the root cause and work closely with you to provide a fast replacement or a mutually beneficial solution.
