Laser cutting is one of the most efficient methods for stainless steel processing, offering advantages such as high precision, smooth cut edges, and high production efficiency. However, in actual production, manufacturers often encounter various cutting defects — ranging from burrs and rough cut edges to incomplete cutting or excessive melting. These issues are closely related to key process parameters including cutting speed, laser power, focus position, and auxiliary gas pressure.

During operation, when electrical energy or other forms of energy are converted into light energy in a laser, a large amount of heat is inevitably generated. If such heat cannot be dissipated timely and effectively, the temperature of the laser will rise, which will adversely affect its output power, beam quality and wavelength stability. In severe cases, the laser chip and internal optical components may even be damaged. Therefore, efficient and reliable heat dissipation is one of the key technologies to ensure stable performance and extend the service life of lasers. With the continuous increase of laser power and the expansion of application fields, heat dissipation technologies are also undergoing continuous development and innovation. This paper introduces the main heat dissipation methods for lasers and their characteristics.

There are no shortcuts to cleaning anilox rolls. Strict and routine cleaning must begin from the first use of a new roll and be performed in accordance with regulations and procedures. Once water-based ink dries inside the cells, dissolving and removing the resin becomes an extremely difficult restoration process. It can only be achieved with great difficulty using a combination of chemical and physical methods, and this process can easily cause irreparable damage to the anilox roll.

Ceramic and metal anilox rolls are high-tech products and very expensive precision core components of flexographic printing equipment. They feature high dimensional accuracy, geometric and positional accuracy, surface roughness, and dynamic balance accuracy. Therefore, this specification for the installation, maintenance and care of ceramic and metal anilox rolls is specially formulated. All flexographic printing positions are required to strictly implement and accurately operate in accordance with this specification. Proper, timely and scientific daily maintenance of ink-transferring anilox rolls can prevent roller damage, extend their service life, and achieve stable and high-quality printing results.
