It feels great! Application of 355nm UV Laser in Marking of Kitchenware Industry

Kitchen utensils, as a common tool for family daily diet, are frequently in close contact with food, which can be directly related to dietary health. Due to the needs of brand promotion or product identification, manufacturers of kitchen utensils will mark certain areas of the kitchen products before they leave the factory.

Kitchen utensils include cooking utensils, dining utensils, cooking utensils, washing utensils and other categories. The materials cover metal, plastic, silica gel, wood, ceramics, etc., some are soft, some are hard, some are brittle, traditional marking methods There are methods such as labeling, ink printing, etc. These methods can no longer meet the increasing health and environmental protection needs of the people, and there are still grooves in labeling that are not easy to tear off.

It is replaced by a new process of laser marking, which is more environmentally friendly, more efficient, more energy efficient and more flexible.

Laser marking on kitchen utensils is also very elegant. For example, fiber lasers can be used to mark metal materials such as stainless steel and aluminum alloys, and CO2 lasers can be used to mark wood and plastic. The use of 355nm ultraviolet nanosecond laser can carry out high-quality marking on metal and non-metallic kitchen utensils.

Keyword 1: do not pick materials

Laser marking is a process in which a part of the surface of a material is instantly vaporized and permanently marked by a high-energy-density laser beam. Nafei Optoelectronics 355nm UV laser has a short wavelength and a narrow pulse width (about 25ns), which has a natural advantage in laser marking. Because metal materials or non-metal materials have a high absorption peak at 355nm, and the single-photon energy of 355nm ultraviolet light is high, the molecular bonds of some materials can be easily broken during marking. This process is athermal and has a smaller thermal effect. , the heat affected zone is small and can be regarded as "cold" processing. This kind of "cold" processing is fundamentally different from the heat treatment of infrared lasers, especially for kitchen utensils made of plastic, silica gel, ceramics and other heat-sensitive materials, the 355nm ultraviolet laser can make up for the deficiencies of laser marking in other bands. .

키워드 2: 고품질 마킹

전통적인 잉크 인쇄 및 마킹 방법은 떨어지기 쉽고 오염되기 쉽고 미세하고 정밀한 마킹을 수행하는 것이 불가능합니다. 355nm 자외선 나노초 레이저의 높은 빔 품질(M2<1.2)과 자외선의 쉬운 포커싱 특성으로 인해 마킹 중에 스폿 직경이 미크론 수준에 도달하고 마킹 라인이 매우 가늘어 높은 경우에 적합합니다. 마킹 요구 사항. 간단하거나 복잡할 수 있고 쉽게 모방할 수 없는 주방용품에 고화질, 고대비 이미지와 텍스트를 표시할 수 있습니다. 현대인의 미학에 맞게 마킹을 더욱 질감 있고 아름답고 아름답게 만들 수 있을 뿐만 아니라 위조를 효과적으로 방지할 수 있습니다. , 그리고 동시에 밀수를 방지하고 다양한 목적을 제공합니다.
