Background

This group is a domestic printing & packaging enterprise, operating 12 Shaanxi Beiren dry laminators that originally relied entirely on manual dosing - requiring 6 dedicated dosing workers and frequently suffering quality incidents caused by ratio errors, making management difficult.

Challenges Faced

• High labor cost: 12 lines needed 6 dosing workers; three-shift coverage strained staffing;
• Frequent ratio errors: large manual deviations once caused a whole batch to be scrapped;
• Quality fluctuation: unstable peel strength led to rising customer complaints;
• Missing data: no way to trace dosing parameters for each batch.

Solution

Gluexpert equipped all 12 Shaanxi Beiren dry laminators across the plant with GB-DL series automatic dosing systems, unifying the metering standard and linking signals with the laminators to achieve "supply on start, stop on shutdown".

Solution Highlights

• Uniform across plant: 12 machines share one dosing logic, standardizing management;
• Dual metering: gear pump + load cell, accuracy ±2%;
• Zero errors: auto-alarm and shutdown on out-of-tolerance, eliminating mis-dosing;
• Traceable data: automatically recorded and exportable.

Results

• 6 workers saved, about 600k RMB/year in labor cost;
• Ratio errors reduced to 0, scrap rate significantly lowered;
• 1.2M RMB total annual savings, payback in 11 months.
