We bend wire into exact shapes. You send a drawing, we return a spring that fits your assembly on the first try. Every piece is verified before shipment, not sampled and assumed.
This collection covers special shaped wire forms: torsion arms, clips, hooks, U-forms, zigzag springs, and multi-bend latches. If it’s not a standard compression or extension spring, this is the line for you.
| Parameter | Value |
|---|---|
| Wire diameter range | 0.1 mm – 12 mm |
| Max part length | 600 mm (straightened) |
| Materials | SWP-A, SWOSC-V, SUS304, SUS316, 65Mn, 60Si2MnA, C17200 beryllium copper |
| Forming process | CNC wire forming (2D/3D), 4-axis servo bending, coiling, stamping for flat features |
| Tolerance (standard) | ±0.05 mm on bend positions, ±0.1 mm on free length |
| Tolerance (precision) | ±0.02 mm on critical angles, verified with CMM |
| Surface finish | Zinc plated, nickel plated, electropolished, passivated, black oxide, or as-drawn |
| Heat treatment | Oil quenched and tempered, or stress relieved per material grade |
| Batch size | 1 – 500,000 pcs, no setup charge for small batches |
| Inspection | Full dimensional report, material cert, hardness test, load test (if applicable) |
| Packaging | Anti-rust paper, plastic trays, or custom EVA inserts for fragile forms |
1. Batch-traceable quality. Each heat number and wire lot is recorded. If a part fails in your field, we trace it back to the exact coil and machine operator. You get a genealogy, not a shrug.
2. Inspection report per batch. You don’t have to ask. Every shipment includes a dimensional report with measured values against your drawing. Critical bends are checked on a CMM, not a protractor. For high-volume orders, we use SPC sampling per AQL 2.5, but we can tighten to AQL 1.0 on request.
3. One factory for CNC, stamping, springs, and heat sinks. Your wire form might need a stamped bracket welded on, or a CNC-machined end fitting. We do all four processes under one roof. That means one purchase order, one quality system, and no finger-pointing between suppliers. It also cuts your logistics cost by roughly 30% compared to using three separate vendors.
Custom wire forms replace cast or machined parts when you need low mass, high fatigue life, or simple deflection.
If your part bends, twists, or holds tension, we can form it from wire up to 12 mm thick.

Q: What is your MOQ? A: No MOQ. We run prototypes from 1 piece. Production batches start at 100 pieces. Tooling is CNC-programmed, so there are no die costs to amortize.
Q: How do you control tolerance on complex bends? A: We use servo-driven wire benders with closed-loop position feedback. After forming, critical dimensions are measured on a CMM. We provide a full report with your shipment. If a dimension is out of spec, we sort 100% before packing.
Q: What is your lead time for a custom shape? A: Prototype (1–50 pcs): 7–12 days. Production (1,000+ pcs): 15–20 days. Urgent orders can be expedited to 5 days for prototypes at a 15% surcharge. We ship via DHL, FedEx, or air freight from our factory in Dongguan.
Q: Can you provide material certificates? A: Yes. Every batch comes with a mill test certificate (MTC) for the wire material, plus our own hardness and tensile test results. For medical or automotive, we can provide PPAP Level 3 documentation on request.
Stop guessing if a supplier can hit your tolerance. Send us your 2D drawing or 3D STEP file. We will review bend radii, springback, and material selection within 12 working hours.
You get a firm quote with unit price, tooling cost (usually zero), and a delivery date. No vague estimates.
