The Craft

Six stages, one factory roof. Here’s how your enamel pin, brooch, keychain or magnet actually comes to life.

Designer preparing custom pin artwork on calibrated monitor
Step 01 / Design

From your sketch to a mold-ready file.

Send us anything — a hand-drawn napkin idea, a JPG logo from your website, a high-res Illustrator file. Our in-house design studio converts it to a clean vector, sets Pantone colors against our enamel color chart, and prepares a 3D mock-up that shows how the finished pin will catch light.

Free unlimited revisions until you sign off. Files never leave our network — we work under NDA by default.

Lead time
3D mock-up in 24h, revisions same-day
Formats accepted
AI, EPS, SVG, PDF, PSD, PNG, JPG, hand sketches
Color matching
Pantone Coated reference + enamel sample swatches
Cost
Free with any production order
Step 02 / Tooling

CNC-machined steel dies in-house.

The steel die-block is the heart of every stamped pin. We engrave ours in-house on three-axis CNC mills — not outsourced — which means we control depth tolerance to ±0.02 mm and can revise the die overnight if a sample shows unexpected behavior.

For 3D pieces (figurine pins, sculptural keychains, resin magnets) we mill a multi-cavity injection mold or silicone master in the same room.

Stamping die material
SKD-11 cold-work tool steel, heat-treated to HRC 58-62
Tooling lead time
3-5 days for 2D, 5-8 days for 3D molds
Tooling cost
$80-200 (waived on orders > 1,000 pcs)
Repeat orders
Die archived 5 years — same Pantone, same dimensions, every reorder

Step 03 / Stamping & Casting

Four hydraulic presses, eight tonnes each.

Brass, copper or zinc-alloy blanks go into the die and emerge with crisp recessed channels for enamel filling or pure relief for die-struck designs. For 3D figurines and PVC keychains we use injection casting from the same studio.

Press capacity
4 hydraulic presses, 80 tonnes each
Base metals
Brass (preferred), copper, zinc-alloy, iron, stainless steel
Tolerance
±0.05 mm on outline, ±0.1 mm on thickness
Output
30,000+ pcs/day across all lines
Step 04 / Coloring

Hand-filled enamel, baked twice.

Each recessed channel is filled by hand with paste enamel through a fine precision syringe. The pin is then baked in a kiln at 180°C, cooled, and inspected under a magnifier. For hard enamel, a second fill, second bake, and machine polishing flattens the surface to a glossy mirror finish.

For offset-print products (button badges, resin magnets) we substitute this step with a 4-color CMYK print + UV cure.

Enamel types
Soft enamel (raised lines), Hard enamel (flush polished), Glow-in-dark, Glitter, Translucent
Print methods
4C offset, sublimation, screen print
Pantone matching
±1 shade on Coated chart, lab-confirmed before production

Step 05 / Plating & Polishing

Twelve plating options, mirror-polished metal.

After coloring, every pin goes through electroplating to give it its final metal finish. Gold, silver, rose-gold, antique-brass, gunmetal, copper, nickel, chrome, dyed black, rainbow, and two-tone — twelve standard finishes plus custom on request.

The exposed metal lines are then buffed to a high mirror polish; the enamel is masked so it stays untouched.

Plating thickness
0.5μm flash, 2μm standard, 5μm heavy (recommended for keychains)
Nickel-free option
Required for EU markets; certified by REACH report
Anti-tarnish
Clear epoxy coat over silver plating to prevent oxidation
Step 06 / QC & Packaging

AQL 2.5 inspection on every shipment.

Eight QC inspectors verify dimensions with digital calipers, check Pantone match under D65 daylight bulbs, test plating adhesion with a tape pull, and confirm clutch attachment torque. Inspection follows ISO 2859-1 AQL 2.5 sampling — an independent third-party (SGS, BV, TUV) can audit at your cost.

Approved pieces move to packaging: poly-bags, hangtag cards, velvet pouches, clamshells, rigid gift boxes — whatever your retail or gifting program needs.

Inspection standard
ISO 2859-1 AQL 2.5 (Major), 4.0 (Minor)
3rd-party audit
SGS / BV / TUV / Asia Inspection welcome at buyer’s cost
Standard packaging
Individual poly-bag + hangtag card, master export carton with packing list
Custom packaging
Velvet pouches, foam-insert boxes, branded sleeves — see packaging service
