УФ-лазер с длиной волны 355 нм для маркировки открывалки для бутылок

Как говорится, «хорошая лошадь достойна хорошего седла», сегодня мы поговорим о вине и его хорошем партнере – штопоре. В жизни штопор для открывания вина слишком обычен и зауряден, и его легко положить на полку после того, как он поработает, и постепенно со временем забыть.

If you "inject" different elements or marks on the bottle opener, including but not limited to product logos, blessings or other graphics and texts, it will reflect a full sense of life ritual, give the bottle opener new value, and then serve as a gift Giving it to relatives and friends, or giving it to customers as a gift from wine merchants can make people feel full sincerity and help to enhance brand promotion.

To make these elements even more recognizable, permanent markings using laser marking give the corkscrew a glow. The mark of laser marking is that the high-energy-density laser beam ablates a shallow layer of the surface of the material, exposing specific graphics or changing colors. Therefore, these characters obtained are particularly obvious to the naked eye, but they are not easy to touch. It is also very soft, smooth and smooth without cutting hands, and has a very texture.

Since the bottle opener is mostly made of stainless steel, or covered with a layer of plastic, wood, etc., the 355nm UV nanosecond laser's non-selective material and "cold" processing characteristics can be well targeted to obtain high-quality marking marks.

The so-called not picking materials means that most materials have a higher absorption rate for 355nm ultraviolet light. Therefore, compared with green light and infrared lasers, high absorption rate means higher marking efficiency, and can realize multi-purpose of one machine at the same time.

The advantage of 355nm ultraviolet light lies in the "cold" processing. The single photon energy of 355nm ultraviolet light is high, and the absorption rate of the material is high. The main performance of the marking effect is that the thermal effect is small, especially for heat-sensitive plastic and wood materials. It is not easy to char and burn, and the marking is clearer. 355nm ultraviolet light is also called "cold" light source.

With the unique advantage of 355nm ultraviolet light, the narrow pulse width of the laser (about 25ns) is also assisting. The narrower pulse width means that the laser energy acts on the material for a shorter time, and the heat accumulation time is shorter, so the heat-affected zone during marking is small, which also helps to improve the marking quality.

In addition, the excellent beam quality (M2<1.2) and the easy-to-focus characteristics of 355nm add a lot to the marking quality. The spot diameter of the 355nm ultraviolet nanosecond laser after focusing is on the order of microns, and the spot obtained after passing through the optical components of the marking equipment is fine, which can be used for fine marking, narrow line width, and easy to obtain high-contrast and high-resolution graphic marks .
