1. Client Background
Founded in 2006 and based in Shenyang, Liaoning, Guandong Paper is a well-established mid-sized packaging manufacturer across Northeast China. Its core business includes the production and distribution of corrugated board and finished cartons, serving local e-commerce and industrial clients steadily.
Rising order volume created obvious capacity limits on outdated folding & gluing lines. After achieving notable capacity growth with the first batch of Kunshan Indeed machines, Guandong Paper kept placing repeat orders for reliable equipment and after-sales support. Currently the factory has invested in 5 Kunshan Indeed machines: 1 industrial carton folder gluer, 3 dedicated models for express carton production, 1 integrated folder-stitcher inline line. Our on-site inspection mainly collected real production data of the 4-fold beam folder gluer for this case study.
2. Original Production Pain Points
1. Low output ceiling: Old folder gluers only reached maximum 450 sheets per minute for 3-ply cartons. Bulk orders required overtime labor, extended lead times and higher staffing cost, limiting capacity for large express carton orders.
2. Heavy maintenance needs: Traditional shaft-driven machines needed frequent lubrication, complicated belt replacement, and suffered frequent jamming that wasted workshop labor hours.
3. Poor line compatibility: Legacy folder gluers could hardly connect with existing new & old flexo printers in the plant; extra reconstruction for inline production brought extra expenditure.
4. Unstable forming tolerance: Poor creasing and folding accuracy caused excess deviation on carton joints, leading to material waste from rejected finished boxes.
5. High power consumption: Older machines consumed large amounts of electricity during long mass production, cutting down overall manufacturing profit.
3. Solutions From Kunshan Indeed
After benchmarking multiple suppliers, Guandong Paper kept selecting Kunshan Indeed folder gluer systems, powered by four core technical strengths to match existing workshop production lines:
• Wide cross-brand compatibility: Our folder gluers work with mainstream printer models on the market, seamlessly connect both new and existing flexo printer slotters in the factory, requiring minimal reconstruction to build inline production workflows and lower upgrade costs greatly.
• Independent full servo structure: No central main shaft inside the machine. All belts on 4-fold beams run with independent servo drives. Belt replacement is fast, regular lubrication is eliminated, and jamming-related downtime is largely reduced.
• Precision forming assembly: Built-in creasing units, forming rollers and seam correction modules keep scissors gap within ±1mm; size error of carton mouth stays at ±2–2.5mm for 3-ply board, ±2.5–3mm for 5-ply board, which reduces rejection rate effectively.
• Industry-leading low energy use: Total rated power of the machine is 50KW, operating power drops to 35KW in mass production (excluding waste removal units), delivering superior energy efficiency among all full servo folder gluer products.
We matched dedicated machines for different production demands: standalone folder gluers for industrial cartons, custom models for express packaging, plus the folder-stitcher inline line for integrated workflow. The deployed 4-fold beam folder gluer takes charge of high-volume mass production.
4. Installation & Measurable Production Results
After full commissioning, under identical staffing and power supply conditions, the customer reached doubled throughput:
• Stable output over 1000 sheets/min for 3-ply corrugated cartons
• 600–700 sheets/min for 5-ply single wall cartons
Compared with the old line’s maximum 450 sheets/min, production efficiency improved dramatically.
On-site feedback confirms easy daily maintenance and responsive after-sales service from Kunshan Indeed, allowing Guandong Paper to take more orders and strengthen regional market competitiveness, with repeated purchases as solid proof of satisfaction.
