MANUFACTURING CAPABILITIES
Custom Chain Manufacturing — From Design to Delivery
From initial design engineering through prototyping, tooling, forming, welding, surface finishing, and final mass delivery — Aurelink's vertically integrated manufacturing capability covers every stage of the chain production lifecycle under one roof.
OEM/ODM MANUFACTURING
OEM & ODM Manufacturing Models
Two flexible manufacturing models designed to meet your brand requirements, from full-spec OEM production to collaborative ODM development.
OEM Manufacturing
Produce chains precisely to your specifications, drawings, and reference samples. You provide the design; we deliver consistent, documented production.
- Full spec compliance from your drawings or samples
- Dedicated tooling and golden sample approval
- Material and finish per your BOM requirements
- In-process QC against approved reference
- Lot-based traceability with mill certificates
ODM Manufacturing
Collaborative development where our engineering team helps refine your concept into a production-ready chain specification, then manufactures to the agreed standard.
- Engineering support from concept to golden sample
- Material and finish recommendation based on application
- Prototype iterations with technical feedback
- Final specification locked before production
- Full production with documented quality control
DESIGN ENGINEERING
Design Engineering Process
Our engineering team translates your concept, drawing, or reference sample into a production-ready specification with full technical documentation.
Specification Review
Technical drawing review, feasibility analysis, and material selection. We assess your requirements against manufacturing capabilities and provide a feasibility report.
CAD Modeling & DFM
3D CAD modeling, link geometry optimization, and design-for-manufacturing analysis to ensure the chain is producible at target cost and quality.
Specification Documentation
Complete technical specification package including dimensions, tolerances, material grade, finish, and testing requirements for production sign-off.
SAMPLING & PROTOTYPING
Sampling & Prototyping
Iterative sampling from first prototype to golden sample approval. Each stage is documented with technical feedback to keep your project on track.
First Prototype
Initial sample from existing tooling or rapid prototype tooling. Validates basic link geometry, material, and finish direction.
Engineering Sample
Refined sample with updated dimensions, finish, and end fittings. Includes dimensional report and basic testing feedback.
Pre-Production Sample
Final sample produced on production tooling. Locked specification becomes the golden sample reference for mass production.
Golden Sample Approval
Signed-off golden sample retained as the production reference standard. All future production batches are inspected against this reference.
FORMING / STAMPING
Forming & Stamping
High-speed automatic forming and precision stamping produce chain components with tight dimensional tolerances under CNC control.
Automatic Chain Forming
Programmable forming machines shape wire into links with controlled pitch, inner width, and geometry for consistent high-volume production.
- CNC-controlled link geometry
- Wire feed automation
- Real-time dimensional monitoring
- Quick changeover for link sizes
Precision Stamping
Progressive die stamping for chain components, end fittings, and decorative elements with tight tolerances and repeatable quality.
- Progressive die tooling
- Multi-station stamping
- In-die sensors for quality control
- Burrs and flash controlled to spec
Automatic Chain Forming Machine
High-speed automatic forming lines producing chain components with tight dimensional tolerances.
Precision Stamping Press
Programmable stamping presses for chain components and end fittings with progressive die tooling.
Wire Drawing Machine
In-house wire drawing to specified diameter with consistent tensile properties across the entire spool.
CNC Cutting Machine
Automated cutting of chain to specified lengths with clean, burr-free ends ready for end fitting assembly.
WELDING / SOLDERING
Welding & Soldering
Precision joining technologies ensure link integrity. Every weld seam is vision-inspected for structural soundness.
Laser Welding
Fiber laser welding closes individual links with minimal heat-affected zone, preserving base material properties and producing clean, strong joints.
- Fiber laser source with ±0.02mm precision
- Minimal heat-affected zone
- Automated vision inspection of weld seams
- Suitable for precious metals and stainless steel
Soldering & Brazing
Traditional soldering and brazing for chain joints where a filler metal is preferred, with controlled atmosphere and flux management.
- Controlled atmosphere soldering
- Silver and brass braze fillers
- Flux residue management
- Post-joint cleaning and inspection
ELECTROPLATING / PVD
Electroplating & PVD Coating
Multi-stage surface finishing from polishing through PVD coating. Achieve consistent color, thickness, and corrosion resistance at scale.
Electroplating
Traditional wet electroplating for gold, silver, nickel, and copper finishes with precise thickness control and batch consistency.
- Gold, silver, nickel, and copper plating
- Thickness: 0.5-10 microns
- XRF thickness verification per batch
- RoHS-compliant plating solutions
PVD Coating
Physical Vapor Deposition for IP gold, rose gold, gunmetal, and black finishes with superior wear resistance and color stability.
- IP Gold, IP Rose Gold, IP Gunmetal, IP Black
- 0.3-3.0 micron thickness
- Superior abrasion and tarnish resistance
- Eco-friendly vacuum process
MASS PRODUCTION
Mass Production Capacity
Vertically integrated production scales seamlessly from prototype to full mass production with consistent quality and on-time delivery.
Flexible order quantities from 500m to 50,000m+. Rush orders accommodated within 2-3 week lead time subject to slot availability.
