Selection tips

  • Set the tilt detents (15-30 degrees is common) together with the locking force, using a spring catch or a tooth disc.
  • A tooth disc outlasts a friction joint but needs a more expensive tool: choose by volume.
  • Thin teeth chip: keep the tooth section thick and prove 500 tilts.
  • Against plastic: a plastic tooth disc is quieter but wears; metal is the durable choice.

Manufacturing process & quality control points

  1. 1

    Product design & tooling

    Qinxi in-houseZinc & Aluminum Alloy Die Casting

    Qinxi owns the tilt joint model and die. The tooth or collar geometry is what holds a parasol at an angle, so the pitch and the locking angle are fixed at design stage.

    Quality control points

    • Tooth pitch and locking angle · Engineering review of the tool plus functional check on first article · Each new tool or project
  2. 2

    Zinc alloy die casting

    Qinxi in-houseZinc & Aluminum Alloy Die Casting

    The joint is cast in-house on the die-casting line.

    Quality control points

    • Fill and porosity at the teeth · Visual under 600-1000 lx, 300 mm · First article + 1 pc per 2 h
    • Tooth profile · Profile gauge / sample assembly check · First article + 1 pc per 2 h
  3. 3

    De-gating, deburring and polishing

    Qinxi in-houseZinc & Aluminum Alloy Die Casting

    Gates and flash are removed and the visible faces are polished in-house. This is part of the die-casting cell, not a separate finishing supplier.

    Quality control points

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

    Plating or coating

    Supply chain / partners

    Coating is applied by the supply chain and checked for thickness and corrosion; a tilt joint that seizes from corrosion is a warranty claim.

    Quality control points

    • Coating thickness and corrosion · Thickness gauge; neutral salt spray (ISO 9227 / GB/T 10125) · Per batch
  5. 5

    Pin fitting and tilt test

    Supply chain / partners

    Pin and catch are fitted and the joint is cycled through its full tilt range under canopy load.

    Quality control points

    • Tilt hold under load · Set at each locking angle with the canopy fitted, no slip · 100%
    • Cycle through tilt range · Manual cycle x10, no binding · 5 pcs per batch
