Why do I need a 3-D Hot-Air Jet Dryer instead of a standard UV dryer?
Solvent-based inks require high-velocity heated air to evaporate solvents off the substrate, whereas UV inks rely on ultraviolet light radiation to initiate instant photo-curing. The hot-air jet system is engineered specifically for evaporative solvent inks used on glassware, plastic drinkware, and metal containers.
How does the high-velocity air jet system work?
The dryer directs targeted jets of heated air over the surface of the printed item. This continuous "scrubbing" action breaks the static boundary layer of solvent fumes surrounding the object, allowing fresh heated air to evaporate the remaining solvent much faster than static heat chambers.
Can this dryer accommodate tall bottles and drinkware?
Yes. Unlike standard flat graphic dryers designed for paper or board stock, the 3-D Hot-Air Jet Dryer features an expanded vertical chamber clearance to easily pass tall cups, water bottles, and promotional containers through the heating tunnel.
Can the belt speed and heat settings be adjusted for heat-sensitive plastics?
Yes. Digital temperature controllers and variable belt speed drives let you precisely fine-tune heat output and tunnel dwell time to safely process heat-sensitive materials like polypropylene and polyethylene without warping or distortion.
