Polyhedral dice

7-Piece Polyhedral Dice Set

A matched set of seven dice - d4, d6, d8, d10, d%, d12 and d20 - sold together for TRPGs. Each die is zinc alloy die cast in-house; numbers are engraved or stamped and filled, plating, enamel and the pouch or box are outsourced. The set is packed together; there is no assembly of the dice themselves.

  • Board games
  • Collectibles & giftsBoxed or pouched gift set

Selection tips

  • For a matched set, lock the plating and enamel colour across all seven dice so they read as one product.
  • Balance matters more than finish: ask for a fairness / roll-test report on the dice, not just a cosmetic pass.
  • Choose packaging against the price point: a pouch is cheapest, a tin or wooden box reads as a gift set.
  • For children-exposed items confirm EN 71-1 sharp-edge and small-parts rules, and REACH lead/cadmium limits.

Manufacturing process & quality control points

  1. 1

    Set design & tooling

    Qinxi in-houseZinc & Aluminum Alloy Die Casting

    Qinxi owns the 3D models and the dies for all seven shapes, so they are made in-house. The set composition and matching finish are fixed at the enquiry stage.

    Quality control points

    • Shape set and finish match · Engineering review of the tool set · Each new tool or project
  2. 2

    Zinc alloy die casting

    Qinxi in-houseZinc & Aluminum Alloy Die Casting

    All seven dice are cast on Qinxi's own line, de-gated and tumbled. Faces and edges are the visible surface, so fill and flash at edges and number recesses are checked per shape.

    Quality control points

    • Fill and porosity at edges and recesses · Visual check under 600-1000 lx, 300 mm distance · First 5 pieces per cavity per shift
    • Edge length and mass per shape · Caliper and balance (0.01 g) · First article + every 2 hours
  3. 3

    De-gating, deburring and polishing

    Qinxi in-houseZinc & Aluminum Alloy Die Casting

    Dice are de-gated, deburred and tumble-polished. This is part of the die-casting process and is done in-house: a clean, flash-free edge keeps the roll true and lets the plating cover evenly.

    Quality control points

    • Sharp edge / burr · Gloved touch check plus 10x loupe · Per lot, AQL 2.5 (ISO 2859-1 general level II)
  4. 4

    Plating

    Supply chain / partners

    Plating is outsourced to Qinxi's finishing partners and verified for thickness, colour and corrosion against the agreed specification.

    Quality control points

    • Coating thickness and colour · XRF gauge; colour check vs master · One set per plating colour per batch
  5. 5

    Numbering and enamel fill

    Supply chain / partners

    Numbers are engraved or stamped and filled with enamel or paint. This is done by the supply chain; legibility and fill overrun are checked.

    Quality control points

    • Legibility and fill overrun · 10x loupe vs master · Per lot, AQL 2.5 (ISO 2859-1 general level II)
  6. 6

    Balance and fairness check

    Qinxi in-house

    Dice are roll-tested for fairness: a large sample is thrown on a flat surface and the face-up frequency is checked against an even distribution (chi-square), and the centre of mass is checked by float or spin. The roll test is run by Qinxi's own QC and the record is kept per lot for the buyer.

    Quality control points

    • Face-frequency fairness (chi-square) · Roll n dice x m throws; chi-square vs uniform · Per lot, agreed sample plan
  7. 7

    Set packing

    Supply chain / partners

    The seven dice are counted and packed into the agreed pouch, tin or box. Packing is done by the supply chain and checked for completeness.

    Quality control points

    • Set completeness and packaging · 100% count and packaging check · Per lot, AQL 2.5 (ISO 2859-1 general level II)
