Fully Automatic Box
Folding Machine
Servo-controlled precision folding for luxury paperboard packaging. 36 pcs/min. 99% qualification rate. Single-operator deployment.
Why Manufacturers Switch to the KY-3250
Advanced Engineering Features
Simultaneous or sequential top/bottom cover production maximises machine utilisation and throughput without additional capital investment.
Ergonomic operator interface with job memory, real-time diagnostics, and parameter recall for rapid job-to-job changeover and minimal training requirements.
Advanced servo drives independently position each folding wall to within ±0.1mm, ensuring crisp corners and consistent box dimensions throughout every run.
Tool-free plate exchange system enables complete format changeover in under 30 minutes, maximising productive uptime across diverse box SKUs and sizes.
3,550 × 1,550 × 2,000mm frame integrates seamlessly into existing production floor layouts without structural modification or power infrastructure upgrades.
High-efficiency servo motor package reduces energy consumption by 35–45% versus legacy hydraulic and pneumatic cam-driven folding systems.

4-Step Automated Workflow
Sheet Loading
Pre-scored blanks are loaded into the dual automatic feeders. The high-capacity magazine supports 50-minute uninterrupted run intervals with no production halt.
Servo Folding
Servo-controlled wall plates fold each panel in precise sequence. Every edge is formed to ±0.1mm — no cams, no mechanical drift, no rework required.
Pressure Bonding
High-pressure platen pressing ensures complete, bubble-free adhesion across the full panel surface for structural integrity and premium unboxing quality.
Conveyor Discharge
Finished boxes are transferred to the integrated stacking conveyor. The operator collects and palletises without interrupting or halting production flow.
Versatile Packaging Applications
Perfume, premium skincare, and beauty gift sets requiring flawless surface presentation and precise interior fitment.
Ring, bracelet, earring, and pendant presentation boxes with exact interior dimensions for premium retail display.
Smartphone, smartwatch, and audio accessory packaging meeting tier-1 brand specifications for the unboxing experience.
Chocolate assortment, gourmet tea, and seasonal gift box production at high volume with consistent presentation quality.
Luxury pen sets, hardcover notebook, and desk accessory presentation packaging for corporate and retail channels.
Sunglasses and prescription frame cases requiring rigid board construction, precision interior fit, and premium exterior finish.

Frequently Asked Questions
Maximising ROI with the KY-3250 Automatic Box Folder
“In luxury packaging, the machine that forms the box IS the product experience. A misaligned edge or inconsistent depth communicates brand negligence. Precision is not optional — it is the specification.”
Servo Technology vs. Mechanical Cam Systems
Legacy cam-driven folding machines rely on fixed mechanical profiles that wear over time, introducing progressive dimensional drift. The KY-3250 replaces every cam with independently programmable servo axes. Each wall position is verified by encoder feedback on every cycle — not once per maintenance interval, but 36 times per minute. This architecture eliminates the root cause of the industry-standard 5% failure rate seen on conventional equipment.
Labour Cost Displacement Analysis
A manual folding team of 15 workers producing 2 pcs/min each yields approximately 1,800 boxes per 8-hour shift. The KY-3250 operated by a single technician produces 17,280 boxes per shift at 36 pcs/min. The productivity differential of 9.6× — combined with elimination of 14 labour positions — typically generates full capital payback within 8–14 months in markets where average packaging labour cost exceeds $12/hour.
Material Compatibility & Sustainability
The KY-3250 is validated across the full premium paperboard spectrum: 210g–350g virgin white cardboard, FSC-certified kraft boards, and specialist textured stocks used in cosmetics and jewellery packaging. The adjustable folding pressure system prevents fibre crushing on lightweight stocks while maintaining sufficient force for heavy 350g boards. The 5KW energy envelope represents a 35–45% reduction versus equivalent hydraulic systems.
