Bring variety to your phone case! 355nm UV laser has high engraving efficiency

Nowadays, mobile phone screens are getting bigger and bigger, and full-screen mobile phones have gradually become a market trend. People rely on clothes and horses on the saddle. The protective case that used to be a mobile phone derivative is no longer a purely practical commodity. In addition to protecting the mobile phone (screen) and prolonging the service life of the mobile phone, the gorgeous turn around acts as a decoration and becomes a part of the mobile phone. New scenery, from a vassal to a necessity.

The survey shows that more than 75% of consumers will purchase mobile phone cases after purchasing mobile phones. The market demand is very huge. However, due to the low manufacturing threshold and strong plasticity of mobile phone cases, the competition in the mobile phone case market is also very fierce.

Only innovation and quality can stand firm in the market.

At present, young people like to follow the trend, pursue high quality, and dislike the sameness, so the workmanship of mobile phone cases is getting better and better, the materials are getting more and more expensive, and there are more and more styles. In addition, the production process of the mobile phone case is simple and can be changed at will, so many consumers use the mobile phone case as the carrier of some IP.

This creates the soil for the personalization and fashion of mobile phone cases, especially with the improvement of digital printing technology, people apply this technology to the production of mobile phone cases, and instantly become a sweet pastry in the mobile phone case market.

Mobile phone cases printed with digital printing technology are mainly produced in batches or small batches, which can meet the needs of consumers to a certain extent, but once the positioning is wrong, it is easy to cause a backlog of finished products and bring losses. needs cannot be met.

The application of laser engraving technology can be used as a complement to digital printing technology, and the beautiful mobile phone case with a specific pattern can be a way to show personality.

Laser has the characteristics of good directionality, high brightness, good monochromaticity and good coherence, and can be widely used in industry, medicine, communication, military and other fields. The 355nm UV nanosecond solid-state laser developed and designed by RFH has excellent performance, good beam quality (M2<1.2), short pulse width (<20ns), high stability, long service life, small size, compact structure, convenient maintenance, and fast engraving speed. , high efficiency, more and more applications in the mobile phone case market.

The mobile phone case is divided into leather, silicone, cloth, hard plastic, soft plastic and other materials according to the texture. The high single-photon energy and high material absorption rate of the 355nm ultraviolet laser are mainly processed by laser photochemical action, also known as "cold processing". When facing these materials of the mobile phone case, it can easily break and recombine the chemical bonds in the material, and leave the body with the deepening of energy, thereby achieving the purpose of engraving. High beam quality (M2 < 1.2) means that the diameter of the spot after focusing by the focusing lens can be within 20 microns, so as to obtain fine engraving effects; short pulse width (< 20 ns) means that the heat cannot diffuse out of the engraving area. It has been stopped, the heat affected zone is small, that is, heat-sensitive plastics, silica gel, etc., the degree of carbonization is low, and there is no melting. The advantages of such cold working are also very obvious, and the processing accuracy is high.
