If you are careful enough, you will notice that there are brand logo, types, length and other information on the surface of the wire. In the past, the majority of wire manufacturers use ink-jet printer to print these information. But this kind of ink-jet printing is polluted and the use cost is quite huge, as the consumption of ink which is a consumable is huge. It is estimated that for medium-sized wire manufacturer, the purchasing cost for the ink can be up to 400 - 500 thousand RMB or even more. And as the demand of the wire industry increases, ink-jet printing can not meet those evolving demands any more.
In this situation, laser marking machine enters into the wire industry. With superior advantages, laser marking machine is quite popular in the wire industry. After being printed by the laser marking machine, the information like production date, batch number, brand logo, serial number and QR code can never be altered. This is quite helpful in anti-counterfeiting the copy products. Although laser marking machine requires a little big investment in the initial stage, it won’t need any consumables and has low energy consumption. Therefore, it has huge benefits in the long run.
For CO2 laser marking machine and fiber laser marking machine, since they rely on “burning” the surface of the wire to realize marking process, it is likely that they will damage the wire surface and there will be smoke occurred.
However, for UV laser marking machine, it realizes the marking process by breaking the chemical molecular bond with the 355nm UV laser light. Because of the short wavelength, the UV laser has very tiny heat affecting zone. Therefore, there won’t be any damage or deformation on the wire surface. And the marking produced is very clear, long lasting, precise and delicate.
Being such a precise marking tool in the wire industry, UV laser marking machine needs to be under stable temperature. The more stable the temperature, the better the laser beam quality. S&A Teyu CWUL-05 portable chiller unit is very ideal in cooling UV laser from 3W to 5W. It features compact design, easy maintenance, top mounted fill port and low maintenance. More importantly, this industrial water cooler can reach up to ±0.2℃ temperature stability. This kind of control accuracy can ensure the UV laser can always maintain at a stable temperature range.
