See the practical checks used to confirm zipper specification, appearance, function and packing before shipment.
Start with the application
Quality control begins with an approved specification. The zipper type, size, length, construction, color, slider and puller should be clear before production starts.
Understand the construction
Appearance review covers tape and teeth color, surface finish, visible marks and the consistency of components. Approved samples provide a practical comparison point.
Confirm functional details
Functional checks include opening and closing movement, slider matching, end-stop security and the requested locking behavior.
Coordinate appearance and components
Measurements and quantities are checked against the order requirement. Packaging, labels and carton information should also match buyer instructions.
Prepare a clear sampling request
Product-specific tests must be agreed in advance. Buyers should state test methods, acceptance criteria and documentation requirements during development.
