FAQ

If solvent residue, environmental compliance and adhesive cost matter (food, pharma), choose solvent-free lamination: 40-50% lower adhesive cost than dry lamination, with zero solvent emission. If high initial tack, wide substrate compatibility or aluminum-foil structures are needed, dry lamination is safer.

Most customers recover the investment within 8-12 months. The payback depends on the number of lines and the original labor and adhesive waste level. See our case studies for real ROI figures.

Ideal for structures requiring high bond strength, temperature and hydrolysis resistance, such as aluminum foil, metallized film, PET and nylon, widely used in food, pharma and new-energy packaging. See PUR hot melt mixer.

Higher line speed needs greater and more continuous mixing capacity. For medium-low speed lines (<300 m/min) a standard two-component mixer is enough; for high-speed lines (≥300 m/min) a high-speed solvent-free mixer or high-speed dry-lamination mixer is recommended.

Gluexpert mixers use gear-pump + load-cell dual metering, delivering stable accuracy up to ±2%, far better than manual mixing with over 5% error.

Yes. Gluexpert mixers support signal linkage with Bobst, Shaanxi Beiren, Songde and other mainstream laminators, auto-supplying adhesive when the laminator starts and stopping when it stops.

Solvent-based two-component (dry lamination), solvent-free two-component, PUR hot melt, and customized multi-component fluids (e.g. new-energy coating, explosion-proof) are all supported.

We provide one-stop service from solution design, installation and commissioning, operator training to warranty, with responsive remote diagnosis and on-site maintenance.

Common issues include ratio deviation, unstable output, alarm shutdowns and metering-pump noise, mostly caused by insufficient material, air in the line or sensor drift. Contact our engineers for a troubleshooting guide.

The machine is PLC-controlled and uses gear pumps and load cells for dual metering. Following the set ratio, a servo precisely controls the dosing of main agent, curing agent and solvent into the mixing tank. The mixing tank then performs a secondary weighing based on the incoming adhesive amount, comparing the actual quantities of main agent, curing agent and solvent to double-guarantee ratio accuracy. After thorough blending in a dynamic mixer, the adhesive is transferred to the circulation tank, from which a diaphragm pump continuously circulates the material to the laminator glue pan.

The machine is PLC-controlled; precision gear pumps draw the main agent and curing agent of the solvent-free adhesive separately. After accurate metering at the set ratio (e.g. 100:50 or 100:100), the adhesive is conveyed through heated, insulated hoses to a static mixing tube for uniform blending, then supplied continuously to the laminator coating unit. The system is equipped with temperature, pressure and flow monitoring to keep the mixing process stable and controllable.

The core uses a platen melting structure: the platen slowly presses down from the top of the adhesive drum. A PLC intelligent temperature-control system melts only the layer of adhesive in contact with the platen. The melted adhesive is then delivered through insulated hoses to the coating station. This 'melt-on-demand' design keeps the adhesive always fresh, avoiding the aging and carbonization caused by prolonged heating in traditional melters. A high-precision temperature-control unit keeps the melt temperature precisely within 120-150℃, ensuring optimal PUR flow and reactivity.
