A complex 3D part — not every factory will take it on
CNC bending with no limits on bend count or spatial geometry
Custom Wire Forms — CNC Bending to Drawing
Not just springs: hooks, clips, retaining rings, frames, retainers, fasteners. We bend wire on CNC machines — with no limits on the number of bends or three-dimensional geometry.

Problems we solve
Your problem — our solution
The drawing exists but needs to be adapted for production
Our engineer helps optimize the design and reduce unit cost
Material and coating must match the other springs in the assembly
Same steels and coatings: zinc, nickel, cataphoresis, Dacromet
Technical parameters

Process
How we make it
- 01 CNC bending
- 02 cutting
- 03 radius bending
- 04 welding if required
- 05 heat treatment
- 06 coating
Wire is sourced directly from Baowu (Baosteel), Kobe Steel, Bekaert and Qingdao Special Steel — that is what gives consistent characteristics from batch to batch.
Applications
Where this category works
- Fastening and retaining elements
- Retaining and spring rings
- Frames and brackets for equipment
- Electrical and household appliance parts
- Agricultural machinery and auto accessories
Advantages
Why factories choose XULONG SPRING
Proof, not promises
Quality control of every batch
What removes the risks of sourcing from China
- NDA on request Drawings and technical documentation are never shared with third parties or used for other customers.
- Prototypes in 48 hours You test the samples first — series production is agreed only after your approval.
- Reports for every batch Load, geometry, hardness — with measurement protocols and batch traceability.
- Document package for EAC IATF 16949:2016 certificate, test reports and product data sheets — for declaration and customs.
- Payment in CNY Payment terms and channel are agreed individually before the order is signed.
- Delivery to Russia Rail, road and sea freight via the Far East. Incoterms: FOB, CIF, DAP.
How to start — three steps
- 01
Send a drawing or a sample
PDF, DWG, DXF, a sketch or a physical sample. We sign an NDA on request.
- 02
Get a price and lead time
Our engineer checks manufacturability and proposes material and coating — we reply within one business day.
- 03
Test prototypes in 48 hours
After alignment we produce prototypes and ship them to you. Then — a series batch with inspection and documentation.
FAQ
Questions about wire forms
Can we order these wire forms made to our drawing?
Yes. We accept drawings in PDF, DWG and DXF, sketches and physical samples. Standard prototyping lead time is 48 hours after the drawing and material are approved.
Which material and coating do you recommend?
The selection depends on the operating conditions: temperature, load and environment. Our engineer will propose a steel grade (65Mn, 60Si2Mn, 55CrSi, 51CrV4, etc.) and a coating — from zinc plating to Dacromet.
How are the price and minimum order calculated?
The price depends on wire diameter, material, coating and batch volume. Send a drawing with the required quantity — we will reply with a price, lead time and minimum volume.
How do you deliver products to Russia?
We arrange rail container transport, road freight and sea shipping via Far East ports. Delivery terms (FOB, CIF, DAP) are agreed per order.
Can we sign a confidentiality agreement?
Yes, we work under NDA: customer drawings and technical documentation are never shared with third parties or used for other customers.
