Quality laser printing machine provider: You can laser etch a wider variety of materials, including steel, aluminum, anodized aluminum, lead, magnesium, and zinc. There’s also a unique method called laser annealing to mark metals like stainless steel. From Solid to Gas: How It Works: Whereas laser etching melts the material surface to change its roughness, laser engraving sublimates the material surface to create deep crevices. This means that the surface instantly absorbs enough energy to change from solid to gas without ever becoming a liquid. Read extra info at cosmo laser equipment.

Laser marking machines use laser beams to reveal the deep of material or cause physical changes in the object, then operational traces appear so that the material emerges with the desired graphics, images, text, and other permanent marks. Laser marking processing is divided into two types: thermal processing and cold processing. In thermal processing, a high-energy-density laser beam is irradiated on the surface of the material being processed. The absorbed laser energy causes a thermal excitation process in the irradiated area, causing the temperature of the material surface (or coating) to rise, resulting in metamorphism, melting, ablation, evaporation, and other phenomena.

High brightness – Lasers are the brightest light source of our time, comparable only to the intense flash of a hydrogen bomb explosion. The brightness of sunlight is about 1.865 × 109 cd / m2, and the output brightness of a high-power laser can be 7 to 14 orders of magnitude higher than that of sunlight. Although the total energy of the laser is not necessarily large, because of the high concentration of energy, it is easy to produce high pressure and tens of thousands of degrees Celsius or even millions of Celsius in a tiny spot. Practical applications such as laser drilling, cutting, welding and laser marking take advantage of this characteristic.

They can do high-speed cutting on flat surfaces and cylindrical objects such as bangles, rings, etc. They are equipped with a highly efficient material loss recovery design and come with an auto-feed system for conveyor cutting. The CPC-500 is able to cut gold/silver of thickness up to 1.2mm whereas the CPC-500 Excel is able to cut up to 3mm. Cosmo fiber laser cutting machine factory’s CPC-15EV is a water-cooled fiber laser cutting machine. It is highly recommended to cut non-precious metals such as iron, copper, aluminium, lead, zinc, steel, etc. It is able to cut flat surfaces. Its cutting area is 250mm×400mm making it good to cut long strips.

CPM-R uses an industrial-grade diamond pin. It is specially created to mark the inside and outside of rings and bangles and also on flat surfaces. It results in shiny marking without material loss and no need for additional polishing. Controlled by our own in-house software, one can learn to use the machine in the shortest possible time. Its small size, ease of use, and low cost make it the ideal choice in space-constrained retail shops to provide customers with instant customization. Read additional details at cosmolaser.net.

Sparrow20E is a 20W air-cooled fiber laser machine. It is Sparrow20’s split unit. The same functions, small and compact, weighs only 30kg, and comes with WINDOWS-based marking software and a manual. Aside from the need for an additional computer/laptop, the machine is identical to the Sparrow20. Switches are both on the machine and the PC, very simple to use. The CTM-20LCM is a CTM-20L upgrade that includes a position-capturing camera system. It has a positioning feature that eliminates inaccuracies caused by human error in marking. Its design saves time by allowing for automated high-precision assembly line production. It does not have a rotary marking function due to the camera.
