Closures & belt buckles

Magnetic Button / Magnetic Snap

A closure that holds a flap or panel shut with a magnet seated inside two mating metal cups. The cups are stamped and the magnets are bought-in; Qinxi has no stamping or magnet line, so the complete magnetic button is sourced from the supply chain.

Customization
Cup diameter and profile (flat, dome, hidden), Magnet grade and pull force, Reverse-pole safety pair for child-exposed items, Plating matched to the hardware set

Applications

  • Backpacks
  • Crossbody bagsFront pocket or flap magnet
  • HandbagsFlap or frame closure
  • Coats & jacketsStorm-flap or hidden closure

Selection tips

  • Specify pull force against the flap weight: too weak and it drifts open, too strong and it is hard to operate one-handed.
  • For items that may be handled by children, ask about magnet safety (small high-flux magnets are regulated under US 16 CFR 1262 and EU/US toy rules).
  • Nickel-free plating is needed for EU skin-contact items to meet REACH nickel-release limits.
  • Keep magnets away from cards, electronics and mechanical watches; flag this to the buyer for packaging.

Manufacturing process & quality control points

Qinxi in-houseSupply chain / partnersIn-house or supply chain
  1. 1

    Stamping of the cups

    Supply chain / partners

    The two mating cups are blanked and drawn. Qinxi has no stamping or cold-heading line, so this is done by the supply chain to the agreed diameter and plating.

    Quality control points

    • Cup dimension and draw finish · Caliper and 10x loupe · Per lot, AQL 2.5 (ISO 2859-1 general level II)
  2. 2

    Magnet fit and plating

    Supply chain / partners

    A bought-in magnet is press-fitted into each cup and the cups are plated. Plating is outsourced to the supply chain; coating thickness and corrosion are verified against the agreed specification.

    Quality control points

    • Magnet seating and polarity · Seating check; pole verification with a reference magnet · Per lot, AQL 2.5 (ISO 2859-1 general level II)
    • Coating thickness · XRF coating thickness gauge (ISO 3497 / ASTM B568) · One set per plating colour per batch
  3. 3

    Pull-force and closure test

    Supply chain / partners

    The mating pair is pulled apart to confirm the pull force and that it seats squarely without slipping. Supplied and tested by the supply chain, with Qinxi spot-checking.

    Quality control points

    • Pull force and seating · Pull gauge; fit check on the actual panel · Per lot, AQL 2.5 (ISO 2859-1 general level II)
