Cosmetics packaging materials of laser carving process

When after molding, cosmetics packaging products, is needed by the surface treatment, thus the enterprise product information and brand to convey information through graphic way. Common graphic surface treatment of a variety of, here we mainly introduce several common cosmetics packaging industry processes, such as screen printing, pad printing, thermal transfer, hot stamping, water transfer printing, laser carving etc. In this paper, we briefly describes the laser carving the treatment process.

radium vulture is also called laser engraving or laser marking, is a kind of surface treatment technology using optical principle. Radium vulture is a kind of surface treatment, screen printing and pad printing, are printed on the product or design, such as the process is different, the price is different.

a, radium vulture principle

with laser emission of high intensity focused laser beam at the focus, oxide materials and for processing; Play the effect of mark is through material surface evaporation show deep material, either light energy caused by surface physical chemistry physical change is through the light energy to burn out or part of the material, and 'engraved' traces, or light energy to burn, by part of the material, show the etching of graphics and text.

2, process performance

the performance of a laser carving machine, mainly by the engraving speed, strength and light spot size to decide. The speed of movement refers to the laser engraving speed, usually with the IPS ( Inches per second) To represent; High speed with high production efficiency; Speed can also be used to control the cutting or engraving depth, for a specific laser intensity, the slower speed, cutting or engraving depth is greater. Engraving speed can be achieved by a laser engraving machine control panel to adjust, also can use computer print driver to adjust. In the range of 1% to 100%, the adjustment range is 1%. Carving the intensity, the greater the cutting or engraving depth is deeper.

light spot size can be adjusted by using different focal length of lens. Small spot lens is suitable for high resolution carving; Large spot lens is suitable for the low resolution of engraving, but for vector carving it is the best choice; Usually the standard configuration is 2. 0 inches of lens, the light spot size in the middle, is suitable for various occasions

laser carving technology is in addition to screen printing, hot stamping, one of the most commonly used graphic processing technology, in the cosmetics packaging material, common have lipstick tube, air cushion cartridges and other packaging materials commonly used.
