Custom Zinc Alloy Die-Casting Manufacturer for 3D Metal Crafts.

Zamak-5 contains 0.75%–1.25% alloyed copper (ASTM B240), raising tensile strength from 283 MPa to 328 MPa and Brinell hardness to 91 HB. For heavy craft-brewery bottle openers, Zamak-5 prevents pry-lip deformation and jaw snapping above 48 N·m leverage torque across 5,000+ steel crown caps.

Cheap factories hot-glue bare magnets onto flat plated backs, which fail when sea containers hit 60°C. We die-cast a 0.8mm recessed mechanical pocket, plasma-clean the cavity, and bond Ni-Cu-Ni coated N52 neodymium magnets using two-part toughened structural epoxy (>18 MPa lap shear).

Tier 1 Agile Customization starts at MOQ 200 pcs using our existing bottle opener blanks, standard coin dies, or classic trinket box shells with custom laser engraving or enamel crests. Tier 2 Bespoke 3D Steel Tooling starts at MOQ 500 pcs, and 100% of your mold fee is refunded once cumulative re-orders reach 5,000 units.

Yes. We melt 100% virgin ASTM B240 Zamak ingots—never recycled battery or plumbing scrap. Every batch is screened on our benchtop XRF spectrometer to ensure total Lead (Pb) < 15 ppm and Cadmium (Cd) < 10 ppm, passing US CPSIA, California Prop 65, EU REACH SVHC, and EN71-3 toy safety.

For complex 3D figurines and ornate trinket boxes, our toolmakers build 4-slide hydraulic core-pull H13 steel molds, routing witness seams along natural armor ridges or filigree borders, followed by ceramic vibratory tumbling and hand sisal buffing before electroplating.

Phase 1: Free 2D/3D relief sculpting & DFM mold-flow review within 12 hours. Phase 2: Rapid 3D prototype or pre-production sample in 48 hours (5–7 days for full H13 steel mold T1 sample). Phase 3: Mass production in 12–16 business days, with air DDP (4–6 days) or sea DDP door-to-door.
