Laser color metal engraving

The functionality and aesthetics of laser engraving on metal allows this simple technology to be used everywhere – from decorating lighter cases to creating type plates for the aerospace industry. The metal and the design on it look attractive.

We are a company that professionally engraves metal surfaces with lasers. We will quickly and efficiently apply the necessary information on the desired product, and the price will satisfy the customer.

Capabilities of the method

The task of the service is to create an image, a logo or a simple word directly on a metal part:

  • laser engraving on metal provides information about the marked product or its parts;
  • indicating formal data: name, manufacturer, production date or batch number;
  • informing the user about the functionality of the object by marking a control and monitoring element (switch, indicator or handle);
  • laser branding of the product by means of monochrome or multicolor engraving;
  • affordable price.

The result, applied with special equipment, is of high quality – it looks harmonious, has no significant roughness, the metal requires no additional machining or etching.

Technical solution to laser engraving on metal

The process of creating an engraving is to remove a layer of metal under the influence of the ultraviolet beam. The energy applied to the material, strongly heats it – it is melted and locally vaporized.

The laser beam, reaching the surface, concentrates the energy on a tiny spot, the size and shape of which is controlled by the machine’s lenses. The position of the focus point affects the depth of the vaporized surface layer.

Another interesting thing is that it is possible to create a color image. For this purpose, we have equipment designed to generate emission with the required wavelength and energy, which is converted into color on the metal. Equipped with a scanning system, the equipment forms the desired pattern with high accuracy.

Color reproduction

The depth and hue of the color depends on a list of factors:

  • the type and thickness of the metal;
  • power and properties of the surface oxidized layer;
  • thermal properties of the material;
  • characteristics of the laser pulse output – power, frequency.

By selecting the parameters, the operator of the engraving machine determines the technical possibilities of formation of transitions, their coloring gradients, finished colors and their saturation.

At the same time with the target colors in engraving can be formed blueing: a peculiar result of local physico-chemical transformations in the form of a fresh film of oxide compounds. This looks like an area painted in overlapping colors.

Laser imaging is allowed for stainless steels, titanium, nickel-plated surfaces, brass, zirconium – all those that are prone to oxidation.

The technology of engraving consists in spot focusing of laser beam – it does not bring energy to surrounding layers of material (similar to welding arc), as a result of which only irradiated spot changes its color. We use a fiber laser: it provides color engraving with minimal energy loss.

Advantages of color laser metal engraving technology

We are ready to help any customer with a colored image, which casts a beautiful sheen and pleases the eye with a game of pearlescent colors.

It is impossible to make something similar with any other technology, laser engraving on metal options is an inexpensive key to the recognition of the customer’s product. We work in Europe.
