In the fast-paced post-press industry, efficiency, automation, and consistency are the key to outperforming competitors and meeting high-volume production demands. From collecting folded signatures to stacking and bundling finished products, every step requires reliable equipment that eliminates manual labor, reduces errors, and ensures seamless integration with existing production lines. Introducing the power duo: the HXDK520 Automatic Vertical Stacking and Bundling Machine and HX500 Vertical Stacker and Bundling Delivery. Together, they form a comprehensive post-press solution that transforms stacking and bundling workflows, minimizes bottlenecks, and elevates your production capacity.

The HXDK520 Automatic Vertical Stacking and Bundling Machine is a fully automated post-press workhorse, designed to integrate seamlessly with web press printing machines or paper sheet folding machines. Its core function is collecting folded signatures vertically, achieving this by pressing and flapping the stack to ensure neat alignment before pushing it to the bundling station. It automatically inserts clapboards at both ends of the stack and applies 3000N pressure to press and bundle the stack automatically, ensuring secure, uniform bundling.

A standout feature of the HXDK520 is its fully automatic operation, specifically engineered for large-run folding signatures production. It requires no laborers, completing the entire folding, collecting, stacking, and bundling process with intelligent automation. This not only eliminates manual labor costs but also reduces human error, ensuring consistent results even during high-volume, continuous production runs.

Complementing the HXDK520, the HX500 Vertical Stacker and Bundling Delivery boasts a high storage capacity for folded or bound products, making it particularly suitable for medium to large-run processing. It features an integrated pressing unit that exhausts air from the stack, effectively improving folding quality by eliminating air gaps and ensuring tighter, neater stacks.

The HX500 combines delivery and bundling functions into one seamless system: operators can set the desired signature stack number, the machine flaps the stack to ensure neatness, then pushes it to the bundling station where it applies 3000N pressure to press and bundle folded sheets (signatures), brochures, book blocks, and other post-press products. Its versatile design makes it ideal for industrial signature production and perfectly suited for seamless integration with subsequent post-press processes.

Together, the HXDK520 and HX500 form a complete post-press stacking and bundling solution: the HXDK520 handles fully automatic, labor-free large-run production, while the HX500 caters to medium to large runs with enhanced storage and folding quality. Their synergy streamlines post-press workflows, reduces labor costs, and ensures consistent, high-quality bundling—making them indispensable assets for any modern printing and post-press facility.
