What is hand-gluing used for? Hand-gluing (manual box assembly): suitable for irregular shapes, thick boards (greyboard gift boxes) and high-end product lines (requiring hand-crafted details); as hand-gluing is a slow process (with limited output), sufficient lead time must be allowed when scheduling.
The final stage in box production is ‘gluing’: whilst machines on an assembly line work quickly, experienced craftsmen achieve greater precision by hand — if the wrong gluing method is chosen, one must compromise on either efficiency or a premium finish. This article clearly explains the division of labour between machine and hand gluing.
The gluing of packaging boxes is a ‘division of labour between machine and handwork’: machine gluing handles high volumes, whilst hand gluing focuses on precision — the choice depends on whether the box is intended for shelf display or as a gift box; for high-volume production, do not complain about roughness, and for precision work, do not rush the process.
How to verify? Box assembly verification: bend the box (to check for delamination), inspect the edges (for excess or missing adhesive); for machine-assembled boxes, conduct batch spot checks (opening and closing 100 times). For small-batch verification, produce a sample box first before proceeding to mass production.
How to categorise? Standard designs are machine-assembled, whilst irregular shapes and thick boards are hand-assembled — categorised by box type; High-volume machine gluing, small-batch hand gluing (also used for prototyping) — categorised by quantity. Follow the production instructions for box gluing methods.
How should the adhesive be prepared? Adhesives for box gluing (white latex glue, hot melt adhesive): use hot melt adhesive (quick-drying) for machine gluing and white latex glue (adjustable) for hand gluing; adjust the drying time (for pressing the box) according to the season.
What is machine assembly used for? Machine assembly (using a box-making machine): fast production runs (several thousand per hour) and low cost; generally used for standard coloured boxes and six-panel lids; machine setup (edge alignment) must be consistent.
