Case history

In Mould Labelling (IML)

The first test concerns an application on a GIDUE Combat 530 for in mould labelling printing.
UV Ray uses a 190-W/cm, 580-mm reflector, with digital feeder, while the competition offers a 200-W/cm, 550-mm reflector.
The test evaluated the polymerisation quality, with friction tests at different speeds and powers.

Comparing the same speed (70 mt/min) and power (UV Ray with 5% less than competitor maximum power, paltry difference) UV Ray achieves -56% static friction; with 160 W/cm, -20% in specific power compared to the competitor, UV Ray achieves -44% static friction.
Using this excess of curing to improve speed, UV Ray can reach 100 mt/min, +42% more than actual maximum speed with same specific power.
Looking at the performance, it is possible to improve at least by 40% the press operation; looking at the saving, more than a 20% of energy to get same static friction result.

Energy comparison
Starting from 1st January 2016, Europe introduced AEEG 654/2015 requiring a cosφ>=0.95, or a penalty will be applied. UV Ray equipment always runs at a minimum of cosφ>=0.95; so no cost will be added when it runs than the competitor with 4 steps that is definitely not operating at this value, due the obsolete technology used. A significant energy saving coming at no cost. Competitor standby is closer to 50% (around 6 Amps while running at full power is around 12 Amps) – 100W/cm – 5.5kW + blower; UV Ray standby is <=40W/cm – 2.3kW + blower. UV Ray’s blower runs at variable speed as needed; each reflector has its own dedicated blower, for accurate adjustment and lower energy consumption. Competitor single blower is running with a variable speed too, but is a much bigger one: 11kW, reduced at 7.5Kw through its inverter; all the UV Ray’s blowers (6) running at maximum speed are 4kW only; moreover, the reduced speed and air flow on the blower greatly improve the HVAC required and reflect more energy savings than rough numbers only.
