Laser marking machine adopts laser beam to make permanent marks on the surface of various objects. The effect of marking is to expose the deep material through the evaporation of the surface material, or to engrave traces by the chemical and physical changes of the surface material by light energy, or to burn off part of the material through light energy to etch the required text or pattern.
Common laser marking machines include: CO2 Laser Marking Machine, Fiber Laser Marking Machine, UV Laser Marking Machine, Semiconductor End-pumped Solid Laser Marking Machine, etc.
UV Laser Marking Machine ideal for pharmaceutical, medical and cosmetic industry, it resistant to chemicals and sterilization, permanent marks on HDPE/LDPE and synthetic fiber materials.
The machine uses a fiber laser to output laser, and then achieves the marking function through a high-speed scanning galvanometer system. The pulsed fiber laser has the advantages of short start-up time, narrow optical pulse and high peak power. The special design scheme ensures that the laser does not leak when the laser is turned off. Even in special materials, the phenomenon of shadows and virtual breaks will not occur. At the same time, the laser has the characteristics of anti-high reaction and can be processed on high-reflective materials such as aluminium, copper, gold and silver.
Fiber laser marking machine widely used for various metal and non-metallic materials marking, stainless steel, carbon steel, iron, aluminum, copper, anodized and coated metal material, and not-metallic such as nylon, ABS/PVC/PC board, hard plastic, rubber, resin, ceramic etc. It uses fiber laser source and the high-speed scanning galvanometer system to realize the marking function.
CO2 laser marking machine has greater power and higher electro-optical conversion efficiency. It uses Co2 gas as a working substance. The Co2 gas and other auxiliary gas are charged into the discharge tube, and when a high voltage is applied to the electrode, a glow discharge is generated in the discharge tube, so that the gas molecules release the laser light. The laser energy released is amplified and then converted into a laser beam. The laser beam path is changed by a computer controlling galvanometer to achieve automatic marking.
