Your drawing defines the part. We define the process to make it repeatable.
This collection covers special shaped wire form springs—bent, coiled, or formed from wire diameters 0.1 mm to 12 mm. We work from your 2D or 3D CAD file, verify every bend angle and leg length, and ship only after dimensional inspection.
We are a precision manufacturing factory in Dongguan, China, with 20 years of spring-making experience. You send the drawing. We handle the rest.
| Parameter | Value |
|---|---|
| Wire diameter | 0.1 mm – 12 mm |
| Materials | Spring steel (SWP-A, SWP-B), stainless steel (302, 304, 316), music wire, phosphor bronze, beryllium copper |
| Forming process | CNC wire forming (5-axis), coiling, bending, stamping |
| Tolerance | ±0.05 mm on forming dimensions, ±0.1 mm on free length |
| Surface finish | Zinc plating, nickel plating, passivation, powder coating, or as-drawn |
| Heat treatment | Optional—stress relief or full hardening per your spec |
| Batch size | 1 to 1,000,000+ |
| Inspection | 100% dimensional check on critical features, AQL 0.65 on production lots |
| Certifications | ISO 9001:2015, material mill certificates, RoHS/REACH compliance |
Every part is formed on CNC machines with servo-controlled wire feed. No hand bending. No guesswork.
1. Batch-traceable quality Each batch gets a unique lot number. We record material heat number, machine settings, and inspection results. If a problem appears in your assembly line, we trace it back to the exact wire coil and forming program.
2. Inspection report per batch You do not have to trust us blindly. Every shipment includes a dimensional inspection report—measured values for critical bends, leg lengths, and spring rates. We use digital calipers, optical comparators, and load testers. The report is signed by our QC engineer.
3. One factory for CNC + stamping + springs + heat sinks Your project may need more than springs. We run CNC machining, metal stamping, and heat sink production lines under the same roof. One drawing package, one point of contact, one shipping schedule. You save on logistics and avoid tolerance mismatches between suppliers.
Custom wire form springs appear in demanding environments where standard catalog parts fail.
If your part must survive millions of cycles or hold a precise load at a specific deflection, this is the right product line.

Q: Do you really have no MOQ? Yes. We accept single-piece prototype orders. You pay for setup and material, not for a minimum batch. Many buyers start with one sample, test it, then scale to thousands.
Q: What tolerance can you hold on complex bends? ±0.05 mm on forming dimensions is our standard. For critical spring rate, we adjust the forming program iteratively until the load matches your spec. We recommend you specify tolerance on the functional dimensions, not the overall shape.
Q: How fast can I get parts? Prototypes ship in 5–7 working days after drawing approval. Production runs take 10–15 days, depending on quantity and surface treatment. We offer expedited service for urgent projects—call us to check current capacity.
Q: Do you provide material certificates? Yes. Every batch includes a mill certificate for the wire material, plus our own inspection report. For medical or automotive projects, we can provide full traceability documentation.
