Laser marking of components|Laser Marking Techniques

The machine uses a laser to produce a physical or chemical reaction on the surface of the material. The key factors are the energy density, focal length and auxiliary gas.Vector scanning is suitable for complex patterns, and the mask method is suitable for mass production. In actual use, it is necessary to select the power parameters based on the characteristics of the material, and to do daily calibration of focus and gas configuration, in order to ensure that the marking is clear and durable.Mastery of these techniques can significantly increase the efficiency of the process and the quality of the finished product.

The basic principle of laser marking.

The laser generates an energy beam.

This beam, which is less than one-tenth the diameter of a human hair, is produced by exciting specific media (such as CO2 gas or optical fibers) to produce a high-energy laser.

Surface material of the material reacts.

When the laser beam sweeps over the surface of a material such as metal or plastic, it vaporizes the surface material and exposes the color underneath, or it triggers an oxidation reaction that changes the color. This process is like "micro-surgery" on the material.

A common method of laser engraving.

Vector scanning engraving.

Using a galvanometer system to control the laser path, it can draw patterns line by line, like writing with a pen. It is suitable for processing complex logos and QR codes, and is three times faster than traditional pneumatic marking.

(1) Mask projection.

This method is particularly suited to mass production of simple graphics, but the cost of making the templates is high.

The three major factors that influence the effectiveness of branding.

Energy density control.

Different materials need different power levels. For example, aluminum alloy is best for low-power slow carving, while hard metal may need 100W high-power engraving to show color.

The importance of focus adjustment.

The laser beam must be focused on the surface of the material in order to produce a clear mark.

Selection of assist gas.

When processing stainless steel, blowing nitrogen prevents oxidation and blackening, and when processing plastic parts, compressed air can be used to blow away the molten debris. These details directly influence the appearance of the finished product.

Laser Marking in the Automotive Industry

Laser technology has a unique advantage in the automotive parts field, where it can be used for non-contact processing to achieve permanent identification, satisfying the needs of traceability management and anti-counterfeiting.Real-world examples show that this technology can not only improve production line efficiency, but its micron-level precision can also meet the challenge of marking curved surfaces. When combined with a traceable QR code system, it provides a guarantee of product quality. It is becoming an essential step in modern automotive manufacturing.

Five Parameters to Consider When Purchasing a Laser Marker

The key to selecting a laser marking machine is to match it to your actual needs. The five major factors to consider are laser type, power configuration, marking accuracy, the size of the work area, and the software system.Different materials and manufacturing environments require different equipment, and it is also important to consider the quality of the manufacturer's after-sales service and technical support.By taking these points into consideration, a company can avoid wasting money and find the right, efficient equipment.

Comparative Analysis of the Effectiveness of Marking Metal and Non-Metal Materials

The performance of laser marking machines differs greatly depending on the material being marked. Metal marking relies on high power to produce durable markings, and stainless steel and copper require different parameter settings.In actual application, the laser mode must be chosen according to the characteristics of the material. Metals are suitable for industrial marking, while non-metals are better suited to the creative design field. Only by rationally matching equipment parameters can the marking effect be maximized.
