Background

Manager Chen in Zhejiang runs a Shaanxi Beiren DL300 dry laminator that mainly serves "high-end orders" with stricter quality requirements. But in the workshop, the ratio used to depend entirely on the veteran operator's feel, and coating thickness could only be checked by stopping the machine for sampling — once a problem occurred, it often meant scrapping a whole batch, with significant losses.

Challenges

• Ratio by feel: manual mixing had large deviations; consistency between batches was hard to guarantee;
• Thickness by sampling: only by stopping to sample could thickness be checked; full-process monitoring was impossible and anomalies were detected late;
• High scrap cost: lamination defects often scrapped the whole batch; high-end orders could least afford such setbacks.

Solution

To meet Manager Chen's needs, Gluexpert upgraded his dry-lamination automatic dosing machine, keeping ratio accuracy stably within ±1%; at the same time it introduced a US NDC online thickness gauge to monitor coating amount in real time. More importantly, the two systems were linked — when the thickness gauge detects a deviation, the dosing system auto-corrects, forming a "detect–control–correct" closed loop.

Solution Highlights

• Precise ratio: dry-lamination automatic dosing machine with ±1% ratio accuracy, freeing operations from dependence on veteran experience;
• Online thickness: US NDC gauge monitors coating amount in real time, no longer relying on stop-machine sampling;
• Auto-correction: dosing and thickness data are interconnected, deviations auto-corrected, quality more stable;
• Quality closed loop: online detection + automatic control, shifting from "after-the-fact discovery" to "process control".

Results

• Adhesive consumption down 5%-10%: precise ratio reduces waste, mix-on-demand;
• Every roll traceable: dosing and thickness data recorded per roll, clear quality accountability;
• More stable high-end orders: the detect–control–correct loop markedly reduces lamination defects;
• Controllable process: from stop-sampling to full online monitoring, anomalies responded to instantly.

Customer Feedback

Manager Chen said high-end orders come down to stability — a slight ratio drift or thickness error can scrap a whole batch. After linking the two systems, he feels much more at ease — Gluexpert's dosing machine plus the NDC gauge is like double insurance for high-end orders.
