GEW has become a key player in the design and manufacture of UV systems for web coating lines up to 2.50m wide. A range of UV curing equipment is available for all processes, including highly effective short wave mercury arc lamps for hot melt adhesives and long wave UV LEDs for specialist coatings and laminating. GEW will show conventional mercury arc UV lamps, LED, hybrid UV systems, inert-gas UV curing and hybrid power supplies.
Inert gas curing is an important feature in the production of silicone release liners and other processes requiring total polymerization at the highest line speeds. The inert curing process takes place under controlled conditions in a sealed chamber and brings many benefits to the cross linking of acrylic and silicone coatings such as faster production speeds, reduced uncured photoinitiators and the ability to reduce ink or varnish weight.
GEW’s inert atmosphere curing solution can be supplied as a complete new system or as a retrofit and comes with an embedded precision oxygen level analyzer to ensure process consistency and production efficiency. The inert-gas control panel gives the operator a visual feedback and enables him to simply set the required ppm level and the control automatically adjusts the inert gas flow to match the set O2 level and optimize the curing process.
The latest advanced power supplies from GEW can run both LED and conventional mercury arc curing technology as changes in job requirements or ink formulations dictate.
All new UV curing systems with RHINO power supply are equipped, as standard, with GEW’s Embedded Service facility, which allows continuous remote monitoring of the system running condition over the Internet, enabling the manufacturer’s service engineers to detect and correct out of tolerance parameters. This type of remote preventive maintenance ensures the entire UV system operates at peak performance at all times, thus avoiding unplanned machine stoppages and waste of resources.
