Full-Plant Retrofit for a Printing & Packaging Group
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.
