Material and density
Material type, foam density, thickness, and color are checked against the approved sample or order requirement.
Cavity fit
Cavities are checked for position, depth, clearance, finger access, and product retention. A good insert should hold the product without making removal difficult.
Cutting and surface finish
Edges, corners, lamination, adhesive backing, and surface marks are reviewed according to the selected production method.
Packing inspection
Foam can deform if packed badly. Cartons, stacking, compression, and moisture protection are considered before shipment.
Approved sample control
A signed-off sample or confirmed drawing is the reference for production. It should define material type, thickness, color, cavity layout, tolerance direction, and any special notes such as adhesive backing or two-color layers.
Functional checks
A foam insert is checked not only for appearance but also for real handling. Product removal, lid clearance, cavity grip, alignment, and repeated packing should be reviewed before shipping a batch.
Export batch consistency
For export orders, cartons and packing method are part of quality. Over-compression can deform foam, while loose packing can mark edges or change the insert shape during transit.
