Zijtaart, the Netherlands, Erl, Austria – June 29, 2021 - Exergen Global, today announced the integration of their unpowered IRt/c sensor solution into MHM’s screen printing line which stands for innovation, quality and reliability. MHM, founded in 1980 has been a pioneer in the textile screen printing machines segment of which its flash cure excels in versatility.
Flash cure systems are dryers equipped with two different lamps being the MW (medium wave/carbon) and HTL lamps (Halogen Tungsten Lamps). The temperature can go up to 1200°C (2192°F) to 1600°C (2912°F). The challenge is whilst increasing efficiency and curing time, keeping a high-quality print by ensuring that the ink on delicate substrates can’t overheat.
“As technology pioneers, we’re always looking for ways to increase efficiency and quality in the most cost-effective ways possible. There are only a few infrared sensor companies which truly understand the challenges and opportunities in screen printing and that is without any doubt Exergen Global. Their IRt/c line stands for state-of-the-art solutions and services”, said Walter Gatt, CTO of MHM.
The solution was found in Exergen’s IRt/c.03 temperature sensor. This sensor provides a 3:1 field of view and can therefore be positioned behind the lamps. The IRt/c.03 is cooled by continuous airflow to prevent overheating. From its position, the sensor has a clear view of the printed t-shirts and measures the temperature fast and very accurately. As it measures the dry-out point it provides input when print out has sufficiently dried.
“Flash cure creates complex thermal management challenges. The need for a temperature solution was a must as the ink cannot be overheated as it will decrease the quality of the print”, said Bram Stelt, CEO of Exergen Global. “As we have an in-depth understanding of the thermal management challenges in screen printing, we were able to provide the right IR sensor solution which will enable the operator to optimize the speed of drying, and thus the speed of t-shirt printing without jeopardizing the print quality”, he added.
The IRt/c sensor from Exergen makes it possible to measure the exact t-shirt temperature during the curing process, by employing sensors with a resolution of approx. 0,0001°C (0.0002°F) and a repeatability error of 0,01°C (0.02°F). Once the user implements the parameters of kind of textile, color and ink, the optimal curing temperature will be known, and the sensor will indicate when it overheats. This ensures that MHM exactly knows when to remove the t-shirt. Because of the solutions that the teams of MHM and Exergen brought, MHM can increase the intensity of the radiant lamps, which produce more heat. Doing this and being able to control it, MHM increases the efficiency/speed of the process whilst prohibiting that the ink on delicate substrates loses quality.
MHM Transfer Foil Curing Machines: Perfection in screen printing
The Exergen IRt/c sensor lines are extremely reliable with the highest performance and the following features: Self-powered, intrinsically safe, repeatability 0,01°C (0.02°F), resolution approx. 0,0001°C (0.0002°F) and very important, an interchangeability of +/- 1%. One of the main reasons for the unique performance of the IRt/c.03 is the custom designed and built thermopile-based sensor.
