Laser marking machine: description, types, areas of use

laser marking machines are most often used to apply high-strength information and images. Engraving produced by a laser marking machine is considered one of the best in our time. It does not disappear when exposed to external ultraviolet radiation, sun, moisture, is not subject to corrosion and is not afraid of mechanical damage.

Decent speed, accuracy and precision in performing work make laser equipment in demand in reputable industrial companies.

Display

A laser marking machine is a specific machine for non-contact application of information on the surface of products. One of the real advantages is working without consumable raw materials.

During the marking, the laser beam draws texts along the outlines of signs and symbols, burning the surface layer of the product. When applying complex images to rolled metal workpieces, their configuration and anti-corrosion parameters are not violated.

Innovative marking devices are entirely automated, for this reason defects are impossible. The adaptability of options makes it possible to select the best parameters directly for a specific production cycle and type of material.

Type of material used

Laser markers are universal; a wide range of settings can make it possible to use them to perform work on:

• laser marker for metal and alloys;
• glass;
• skin;
• ceramics;
• plastic;
• silicone;
• rubber;
• plastic;
• tree.

Laser marker type

There are several different types of laser markers available:

• gas CO;
• ultraviolet;
• solid state;
• fiber optic;

1. The ultraviolet marker is high-tech; it acts as a “cold marking”. It is used when working with flexible printed circuit boards, packaging materials, glass – precisely where excessive thermal exposure is undesirable due to the possible deformation of the workpieces.
2. The fiber machine produces laser beams of very high intensity. At its source is a doped transparent fiber. High-power LED devices serve as the light supplier. Fiber optic modules are compact, very reliable, and do not require special maintenance.
3. CO gas laser is usually used to work with acrylic, wood, and leather goods. In the main section of the device there is a mixture of nitrogen, helium and carbon dioxide. Under the influence of an electrical impulse, it emits photon particles. The laser beam is supplied to the focusing lens through a gas-discharge tube and an optical mirror system. The equipment is structurally complex and bulky.
4. A solid-state engraver on a vanadate crystal is used where a considerable depth of field of focus, high beam quality and a short pulse length are required. The combination of all of these elements produces a high-contrast image in complex production situations where the use of a standard fiber optic device is ineffective.

Scope of use

• The areas of application of laser devices are endless:
• Production of tobacco products.
• Leather goods.
• Packaging materials.
• Jewelry production.
• Beverage production.
• Pharmaceuticals.
• Production of rolled pipes.
• Mechanical engineering.

Manufacturing companies

Companies from Europe, China, the USA, and Russia are engaged in the development and production of laser devices. American and European devices belong to the VIP-class segment, designed for intensive use in labor-intensive production situations. The performance and declared power meet the needs of solid businesses. Chinese-made analogues will be useful for small and medium-sized businesses.
