Different from the evaporation of surface material to expose deep material, the main working theory of long-wave laser, the effect of UV laser marking machinehttps://www.zhongweilaser.com/product/d ... ttachment/ is that the molecular chain of material is directly interrupted by short-wavelength laser to display the desired etched pattern and text. It has much small thermal impact zone and thus can greatly reduce the mechanical deformation of material.
Therefore, UV laser marking machine is mainly used for ultra-fine marking and engraving, especially suitable for marking & micro-hole marking of food, pharmaceutical packaging material, high-speed division of glass, porcelain materials, and complex graphic cutting of silicon wafers, etc.
Advantages of Jeesun UV laser markerhttps://www.zhongweilaser.com/product-c ... er-marker/ machine:
1). Reduce product damage
small heat-affected zone, so the damage to material can be avoided
2). Fine marking performance
The spot diameter of a laser is greatly affected by the wavelength of light. The UV wavelength, 355nm, is 1/3 of the basic wavelength (1064nm), so the spot size can be reduced and marking can be performed in a limited space.
3). high marking speed
UV laser marking machine has high average power and high repetition frequency, so the marking speed is faster, which can effectively improve production efficiency.
