As market demand increases, in order to satisfy the market and make products more differentiated, the water cup factory continues to innovate the spraying process on the surface of water cups, especially stainless steel water cups. In the early days, only ordinary paint was used on the surface of the stainless steel water cup. This method will cause the surface of the water cup to be less resistant to friction. After the water cup is used for a period of time, the paint on the surface of the water cup will fall off. Therefore, various water cup factories continue to improve their technology and continuously improve the firmness of water cups after surface treatment. As a result, pearlescent paint, texture paint, ceramic paint, hand paint, hand oil, rubber paint and plastic powder spraying have appeared on the market. The continuously optimized spraying effect has been significantly improved, both in terms of wear resistance and the presentation of the sprayed surface effect.
In recent years, laser engraving technology has been applied to the surface treatment of water cups. Usually, graphics and various forms of logos are engraved on the surface of water cups through laser engraving technology. So under various spraying processes, can laser engraving maintain consistent laser engraving effects on water cups treated with different spraying processes?
The answer is obviously no. Stainless steel water cups with spray-painted surfaces are relatively suitable for laser engraving. Since the spray paint coating is relatively thin and the paint becomes hard after high-temperature baking, the high-temperature burning process of laser engraving can produce a good graphic display effect. Due to the high viscosity, high hardness and thick coating of the plastic powder, the laser engraving process is more difficult than the spray-painted stainless steel water cup. Low-power engraving may not be penetrated and high-power patterns may become black. . After the rubber paint and touch oil process are used on the surface of the stainless steel water cup, it is not recommended to use laser engraving process. Because the rubber paint and touch oil are soft, have a low melting point, and have a higher viscosity, it is difficult to ensure the integrity of the pattern after laser engraving. After high-power operation, although the pattern can be carved out by laser, severe burn marks will appear around the pattern, which is difficult to handle.
Before deciding to use laser engraving technology, please understand the power and usage instructions of the laser engraving machine, so that you can better use the laser engraving machine to create perfect graphics.
