Application of RFH 355nm UV Laser in Ceramic Engraving

Porcelain is an important cultural heritage of the Chinese nation and an important feature of Chinese civilization. It can be called my country's "fifth greatest invention". my country's reputation as "the country of porcelain" is well-known all over the world. The English word "china" means porcelain, making "China" and "porcelain" an inseparable pun.

Porcelain is derived from pottery. It is a glaze fired at high temperature on the surface of the vessel. Different firing conditions and different raw materials bring different glazes. It has the characteristics of various colors, hard texture and high temperature resistance. This is also porcelain. Each has its own characteristics and is exquisite. Even though all kinds of metal utensils and utensils are emerging in an endless stream, the pots and pans made of porcelain are still popular, and through the addition of modern technology, patterns, patterns or words are engraved to give porcelain more value.

Porcelain is similar to glass, sapphire and other materials, and is a hard and brittle material. If you want to engrave on the glazed surface, and meet the requirements of small chipping, clear engraving graphics and information, and permanent, then such equipment is not a UV laser.

RFH ultraviolet nanosecond solid-state laser, the output 355nm ultraviolet laser is a cold light source, the single photon energy is very high, the pulse width is very narrow (<20ns) and the peak power is very high. The destruction threshold of hard and brittle substances such as glass and sapphire can be used for high-quality cutting, drilling and marking; excellent beam quality (M2<1.2) after focusing, the spot diameter after focusing is micron, about 20-30 microns , the edges of the graphic and text obtained during engraving are clear, and the line transition is soft and continuous. The high flexibility of laser processing is also unmatched by traditional engraving methods. With the assistance of computer programs, it can be accurately positioned even on the surface of the curved porcelain surface, and the fixed-point operation can be performed to complete the processing easily. It has fast engraving speed and easy operation. Simple, flexible processing, changeable styles and so on.

With the requirements of energy conservation and environmental protection and the need for cost control, porcelain enterprises have begun to replace traditional production methods with new processes and new technologies by improving production technology and equipment upgrades to achieve automated and intelligent operations. The application of RFH's industrial-grade nanosecond solid-state laser in the engraving process of porcelain has improved efficiency, improved product quality, and reduced energy consumption and cost, which is in line with the diversified and personalized trend of consumers in the market for porcelain. have to.
