¿Cómo marca la cerámica el láser de estado sólido de nanosegundos de RFH?

El marcado láser es un método de marcado de contacto no directo. Utiliza el efecto especial de la interacción entre el rayo láser de alta densidad de energía y el material. Cuando el haz se irradia sobre la superficie del material, la temperatura de la superficie del material aumenta bruscamente y se evapora instantáneamente. Eliminación de material dejando rastros de marcas.

En comparación con la electroquímica tradicional, la impresión, el estampado y otros métodos de marcado, el marcado láser tiene las ventajas de una alta eficiencia, alta velocidad, alta calidad, gran flexibilidad y ausencia de contaminación. Por lo tanto, el marcado láser ha sido ampliamente utilizado. Según los láseres de diferentes longitudes de onda, es adecuado para marcar diversos materiales metálicos y no metálicos, como plásticos, metales, cerámica, vidrio, películas y cartones.

In the application of laser marking on ceramics, due to the hard and brittle characteristics of ceramic materials, there are strict requirements on the beam properties of the laser and the size of the heat-affected zone during actual marking. The "cold light" property of UV lasers is especially suitable for the marking of such brittle materials. This is the case with the industrial-grade UV nanosecond solid-state laser designed by RFH. It is a high-precision marking for ceramic sanitary ware, ceramic handicrafts, ceramic tableware and other products. A solid choice for:

First, the 355nm ultraviolet laser it outputs has a short wavelength, and most materials have a high absorption rate for it, and ceramics are no exception. It can directly destroy the molecular bonds on the ceramic surface and make the molecules detach from the surface of the object, and this method will not produce High heat and small heat affected zone, so it is called cold working.

The second is the excellent beam quality (M2<1.2), small spot size after focusing, finer micron-level marking, and the delicate texture of the marking, which can make consumers feel the high-quality and high-quality ceramic products.

Third, the permanent marks left by laser marking are durable and can withstand daily washing and washing, as well as the baptism of long years, and are still as clear as new.

Fourth, it can operate 7*24 hours stably. From now on, manufacturers no longer need to replace ink cartridges or chemical solutions regularly. It is safe, environmentally friendly and pollution-free, which is more suitable for the current mainstream trend of environmental protection.

Fifth, whether ordinary characters, numbers, logos or complex graphic patterns, or flat and curved surfaces, or even special-shaped surfaces, RFH industrial-grade nanosecond solid-state lasers can be used for fast marking. The ideal choice for customers who have requirements for standard effects. The marked graphics can not only make ceramic products more aesthetically pleasing and unique, but also effectively enhance the added value of ceramic products.

Epilogue

RFH industrial-grade nanosecond solid-state lasers are widely used. The processing of hard and brittle materials such as ceramics, glass, gemstones, and wafers is inseparable from UV lasers. played a vital role. In the era of "light" processing, the RFH industrial-grade UV nanosecond solid-state laser is undoubtedly a reliable tool for high-quality micromachining.
