Turnkey 6-Step Manufacturing Workflow

Predictable lead times, real-time photographic updates, and engineering-grade execution across every phase.

Phase 01
Engineering review and DFM artwork proofing

1. Engineering & DFM Proofing

Submit your AI, CDR, PDF, or rough sketches. Our mold engineers verify draft angles, metal wall thicknesses, and enamel color lines, returning a photorealistic 3D digital proof in 2 to 4 hours.

Phase 02
High precision CNC steel die tooling

2. Precision CNC Mold Tooling

Tooling crafted using multi-axis CNC carving machines and electrical discharge machining (EDM). We achieve microscopic sculptural relief depth down to 0.05mm with sharp contour fidelity.

Phase 03
Die-casting hydraulic minting and edge cutting

3. Die-Casting & Minting

300T to 1,000T high-pressure die casting for Zamak zinc alloys, and hydraulic minting presses for solid H65 brass. Includes precision lathe rim trimming and custom diamond-cut edge machining.

Phase 04
Dual plating and Pantone color dispensing

4. Color Dispensing & Plating

Robotic micro-injection dispensing combined with master artisan hand-enameling. Multi-bath eco-friendly electroplating (Gold, Nickel, Antique Bronze, or Dual Plating) with Pantone PMS match ΔE ≤ 1.5.

Phase 05
AQL 1.5 quality testing and salt spray compliance

5. Rigorous Multi-Point QC

100% manual surface screening for pinholes, plating blisters, and edge burrs under ISO 2859-1 AQL 1.5 standards. Includes 48-Hour Neutral Salt Spray (ASTM B117) and cross-hatch adhesion tests.

Phase 06

Frequently Asked Questions

Key details regarding 3D proofing, minimum order quantities, rush turnaround, and mold vaulting.

Q: What artwork file formats do you accept for 3D proofing?

We work seamlessly with vector files in .AI, .EPS, .CDR, and vector .PDF formats. High-resolution .PSD or .PNG images are also accepted. If you only possess a hand-drawn concept or raster photo, our graphic department converts it into production vector art without charge.

Q: What is your minimum order quantity (MOQ) policy?

Our standard MOQ is 50 to 100 pieces per design, depending on physical dimensions and tooling complexity. We also support micro-batch prototyping for pilot marketing runs and crowdfunding projects, allowing you to validate market demand with minimal capital exposure.

Q: Can you accommodate expedited rush orders?

Yes. For time-critical marathons, corporate galas, and memorial deployments, we offer an expedited fast-track schedule: pre-production samples in 3 to 5 business days and mass production in 7 to 10 business days, backed by priority CNC scheduling and express courier booking.

Q: Can we request a physical sample swatch kit prior to placing an order?

Certainly. We maintain curated Sample Swatch Kits showcasing our various metal bases (Zinc vs Solid Brass), plating finishes (Shiny, Antique, Dual Plating), edge cuts, and enamel types. Sample kits are provided free; clients only cover standard international express shipping.
