Machine Knowledge

Rigid box machine accuracy mainly refers to the positioning error between the target position and the actual position: the smaller the deviation, the higher the accuracy. For example, ±0.10 mm represents higher positioning accuracy than ±0.15 mm, while ±0.15 mm is more precise than ±0.20 mm.

Most automatic rigid box machines are rated at about 20–60 pieces per minute (pcs/min). Semi-automatic equipment typically runs at 10–25 pcs/min, standard automatic machines at 20–40 pcs/min, and high-speed machines at 45–60+ pcs/min. A few specialized systems can reach about 65 pcs/min.

Making a rigid box usually requires several machines, not one universal rigid box machine. A typical process may use equipment for greyboard cutting, grooving, corner pasting or box forming, paper gluing, positioning, wrapping, edge folding, case making, lining, assembly and finishing. The exact combination depends on the box structure and on which materials arrive at the factory already prepared.

A fully automatic rigid box machine controls more feeding, gluing, positioning, forming, wrapping, folding and transfer steps in a continuous cycle. A semi-automatic machine automates selected movements but still relies on operators to load, align, transfer or finish components.

Rigid boxes are made by cutting thick greyboard into structural parts, forming or arranging those parts, wrapping them with decorative paper, assembling the components and then adding lining, inserts and closures.

A rigid box machine automates one or more steps used to turn greyboard, cover material or prepared box components into a rigid box part or finished box. Depending on the machine, it may feed and glue cover paper, position board, form a box shell, paste corners, wrap the shell, fold edges, press surfaces or apply an inner lining. The exact working process can only be understood after confirming what enters the machine and what comes out.

A rigid box machine is specialized equipment used to manufacture rigid paperboard packaging through gluing, positioning, wrapping and folding. It typically processes greyboard and decorative cover paper to produce sturdy, precisely finished packaging.
