Decoration & branding

Zinc Alloy Zipper Pull Tab / Puller Plate

The branded plate threaded onto a zipper slider so the wearer can grip it and so the logo travels with every opening. Zinc die casting carries fine 2D/3D relief on both faces and gives a flat plating surface that can be colour-matched to the other metal trims on the same bag or garment.

Applications

  • BackpacksLong pull tab on main-compartment and front-pocket zippers; must clear the slider eyelet without snagging the tape
  • HandbagsSmall polished puller with relief logo; often the most visible hardware on a soft bag
  • Crossbody bags
  • Coats & jacketsCentre-front zipper pull tab; check curvature so it does not scratch the placket
  • Hoodies & sportswearDie-cast pull with soft-touch / silicone insert for grip
  • Denim & workwearFly zipper puller matched to the shank button and rivet finish

Selection tips

  • Confirm the slider model (YKK #3 / #5 / #8 or equivalent) before tooling: eye diameter and post thickness decide how the tab hangs.
  • Mark the cosmetic face and the allowed gate position on the drawing - a mirror face cannot hide a gate mark.
  • Specify plating thickness and salt-spray duration together; decorative trims are commonly called out at 24-48 h neutral salt spray (ISO 9227) with a named acceptance rating, not hours alone.
  • On thin shell fabrics a heavy puller can drag the zipper tape out of shape - check pull force and tape reinforcement together.
  • For children's products every metal trim is an accessible component and must also meet the lead limit; trims are a frequent cause of failed childrenswear tests.
  • 'Matching colour' is not a specification: agree a Pantone reference and keep a physical approved sample.

Manufacturing process & quality control points

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

    Artwork to 3D relief model

    Qinxi in-houseZinc & Aluminum Alloy Die Casting

    Artwork is rebuilt as a 3D relief model with draft angles; details thinner than about 0.5 mm do not fill reliably in zinc and are thickened at this stage.

    Quality control points

    • Logo legibility at real size · Design review against artwork and 1:1 print · Each new tool or project
  2. 2

    Die-casting tool build

    Qinxi in-houseZinc & Aluminum Alloy Die Casting

    Hardened steel die machined to the approved model. Gate position decides which face carries gate marks, which matters most on the cosmetic face.

    Quality control points

    • Cavity dimension vs drawing · Dimensional report on the first shot · Each new tool or project
  3. 3

    Zinc die casting and de-gating

    Qinxi in-houseZinc & Aluminum Alloy Die Casting

    Zinc is injected under high pressure; runners and flash are removed and parts tumbled. Gas porosity left in the body later shows as pits under plating.

    Quality control points

    • Porosity and cold-shut on cosmetic faces · Oblique-light sample inspection · First 5 pieces per cavity per shift
    • Slide eye seat dimension · Go/no-go gauge at shift start · First article + every 2 hours
  4. 4

    Polishing and pre-plate cleaning

    Supply chain / partners

    Faces are ground, buffed or vibratory polished to mirror or brushed. Residual compound and oil cause plating blistering, so cleaning is audited before plating.

    Quality control points

    • Surface finish vs approved plaque · Visual check under 600-1000 lx, 300 mm distance · Per lot, AQL 2.5 (ISO 2859-1 general level II)
  5. 5

    Plating

    Supply chain / partners

    Plated to the target colour. Buyers normally pair a plating thickness with a salt-spray acceptance level, because the two together decide colour depth and corrosion life.

    Quality control points

    • Coating thickness · XRF coating thickness gauge (ISO 3497 / ASTM B568) · One set per plating colour per batch
    • Corrosion resistance · Neutral salt spray, 5% NaCl, 35 C (ISO 9227 / GB/T 10125) · One set per plating colour per batch
  6. 6

    Enamel or epoxy fill and assembly

    Supply chain / partners

    Recesses are filled with enamel or epoxy and cured; fill should sit below the metal line unless a domed epoxy cover is specified. A jump ring is then fitted so the tab moves freely without opening under load.

    Quality control points

    • Colour match and fill level · D65 light box plus 10x loupe · Per lot, AQL 2.5 (ISO 2859-1 general level II)
    • Link pull-off strength and closing gap · Universal tensile machine, 50 mm/min, record peak and failure mode · Per lot, AQL 2.5 (ISO 2859-1 general level II)
    • Fit on the intended slider · Trial mount on the production substrate with the production fastener · One sample set per batch
