UV laser marking application in warning signs

Warning signs are very common in our daily life. They are used to remind people of special situation in different locations, such as sidewalk, cinema, restaurant, hospitals, etc.. The background color of the warning signs are mostly blue, white, yellow and so on. And the shapes of them could be triangle, square, annular, etc.. The patterns on the signs are easy to read and understand.

Nowadays, the sign manufacturers are facing more and more fierce and fierce competitions. People are becoming more and more demanding on the styles of the patterns on the signs and they require personalization. More importantly, the warning signs need to be long lasting, for the warning signs are mostly placed at the outside and are easy for corrosion of humidity, sun burning and so on. 

To meet those demands, many sign manufacturers introduce the UV laser marking machine. Comparing with traditional color printing machine, UV laser marking machine has faster printing speed and can produce long-lasting markings which won’t fade out as time goes by. Besides, UV laser marking machine doesn’t need any consumables and won’t produce pollution to the environment. 

In addition to warning signs, product;s logo, product type, production date, product parameters can also be printed by UV laser marking machine to achieve identification and anti-counterfeiting function. 

UV laser marking machine is supported by UV laser which is quite sensitive to thermal changes. To guarantee the marking effect, the UV laser has to be under proper temperature control. As a reliable water chiller manufacturer, S&A Teyu developed CWUL series and CWUP series industrial chillers. They all feature high temperature control accuracy from +/-0.2 degree C to +/-0.1 degree C. These industrial chillers are designed with properly designed pipelines, so that it is less likely for the bubble to generate. Less bubble means less impact for the UV laser so that the output of the UV laser will be more stable.
