Selection tips
- A J-shaped or crook handle needs an inner opening of 12 mm or more to hang on a standard hook.
- Pin or bond the handle to the shaft: a push fit alone lets the handle rotate in use.
- Wood-grain transfer print is cheaper and more consistent than solid wood but wears faster, so add a clear top coat.
- Against a die-cast handle: zinc looks heavier and takes complex shapes, but chips at the corner when dropped.
Manufacturing process & quality control points
- 1
Qinxi owns the handle geometry and the injection tool, so grip shape, wall thickness and the shaft bore are fixed in-house at the design stage. The bore size has to match the agreed shaft diameter, otherwise the handle spins or pulls off in service.
Quality control points
- Grip geometry and shaft bore · Drawing review + 3D model check against shaft spec · Each new tool or project
- 2
The injection mould is built and sampled in-house. Gate position matters on a long handle: a gate on the visible grip face leaves a mark the buyer will reject, so the gate is placed at the shaft end or on a hidden face.
Quality control points
- Gate position and fill · First-shot review; no sink, no short shot · Each new tool
- 3
Handles are moulded in-house on Qinxi's injection line. Wall thickness is kept even so the bore does not ovalise, which is what makes a handle loose on the shaft after a season of use.
Quality control points
- Bore diameter · Plug gauge / caliper per drawing · First article + 1 pc per 2 h
- Appearance · Visual: no sink mark, no flash, no flow line on the grip face · Per lot, AQL 2.5 (ISO 2859-1 general level II)
- 4
Gate vestige and parting-line flash are trimmed in-house. Flash on the grip face is a comfort defect, not just a cosmetic one.
Quality control points
- Residual flash · Gloved touch check plus visual · Per lot, AQL 2.5 (ISO 2859-1 general level II)
- 5
Decorating
Supply chain / partnersLogo work - pad printing, hot stamping or laser - is done by the supply chain. Wooden and bamboo versions of the handle are turned and stained by the supply chain rather than moulded in-house.
Quality control points
- Logo position and adhesion · Visual vs approved sample; tape test (ISO 2409) · Per lot, AQL 2.5 (ISO 2859-1 general level II)
- 6
Assembly to shaft and pull test
Supply chain / partnersThe handle is fitted to the shaft by the assembly line and pull-tested. Handle pull-off is one of the most common field failures on a stick or folding umbrella.
Quality control points
- Handle retention · Static pull test; reference 150 N per GB/T 23147-2018 · 5 pcs per batch
- No spin under torque · Manual torque check on the grip · 100%
