As a typical application in the laser industry, laser engraving machine has become the preferred solution for many industries. With the continuous development and progress of laser engraving machine technology, laser engraving machine will completely replace traditional mechanical equipment.
The larger the engraving area of the laser engraving machine, the poorer the corresponding engraving effect. Because the longer the beam of the engraving machine will have more severe resonance (vibration). Half-cutting is a relatively complex process, and the industries that are often used include fabrics, mobile phone buttons, reflective materials, and so on. The flatness of the bottom plate is also required to be very high. Generally, the domestic tube can also meet the flexible requirements for the laser, and the imported tube is better. For different materials of different users, the specific engraving speed and the combination of parameters are not the same.
In the carton packaging industry, CO2 lasers are mainly used for rubber plate engraving. Generally, 50mm focusing lenses are used, and the formats are PLT and BMP. PLT is mainly used for outlines. Both formats have their own advantages, and the specific situation is analyzed in detail. When the height of the engraved characters is greater than 10mm or the strokes of the pattern are greater than 1.5mm, you can use the edging method. Take Yixiu 7mm single-layer ordinary rubber plate as an example. When edging, the surface is humidified with newspaper, and equipped with a leaking air jet cup to prevent blowing. Blow up a large amount of wet newspaper to make the lines more delicate. Adjust as the depth varies, depending on the situation. If the height of the engraved characters is less than 10mm, laser engraving is generally used. The denser or smaller the characters, the smaller the light intensity and the smaller the slope.
