Laser marking machine technology is one of the largest application areas of laser processing. Laser marking, as a high-tech marking means nowadays, is a marking method that uses high energy density laser to locally irradiate the workpiece to vaporize the surface material or undergo a chemical reaction of color change, thus leaving a permanent mark.


Laser marking can hit a variety of text, symbols and patterns, etc., the character size can be from millimeters to micron scale, which has a special significance for product anti-counterfeiting. Relative to the traditional mold, electric corrosion marking, stickers and other marking means, has a fast processing speed, high precision, never wear out and other characteristics; at the same time the laser marking belongs to a non-contact processing, no mechanical effect in the process of processing, and will not damage the processing of the material on the surface of the goods, so now the automobile manufacturers in order to ensure that the marking of the parts of the effect of the parts on the extensive use of laser for parts and components Information marking. And laser equipment using computer software control system, strong compilability, stable performance, not only can the pattern of auto parts text editing, but also to meet the needs of mass production and personalized customization needs, for the current automotive design and manufacturing to provide more space to build.


Now people value the performance of the car at the same time, for the safety concerns are also increasing, automotive parts belong to the multi-species, large-scale production, the current quality control is mainly used in the way of sampling, belongs to the aftermath of the inspection, can not play a preventive role in the production process, control. And now through the information traceability we can change the quality control from the aftermath of the gatekeeper to prevent beforehand, laser marking in this link plays an important role, the use of laser tagged parts information, we can through online monitoring, timely detection and elimination of abnormal parts and components, to prevent the production of defective products and inspection of product quality; and can also be those who failed to detect defects in the production of products, we can through the parts marked on the top of the defective products, we can use the laser marking on the top of the defective products, we can use the laser marking on the top of the defective products. We can be marked through the parts above the information, information traceability, so as to quickly determine the cause of defects and batch, in time to do a good job of rapid response. This not only effectively improve the quality of auto parts, but also to ensure the safety of automobile driving, so that each of our automobile passengers an additional safeguard, to avoid some of the accidents caused by minor faults.


Laser marking machine features-Suntop


In the field of auto parts processing, laser marking machine is mainly used for marking information such as 2D code, barcode, plain code, production date, serial number, Logo, pattern, certification mark, warning mark and so on. Including automobile wheel arcs, exhaust pipes, engine blocks, pistons, crankshafts, audio translucent buttons, labels (nameplates) and other high-quality marking of a variety of accessories.


Advantages of laser marking:

1. The use of laser marking as a means of processing, and no processing force between the workpiece, with no contact, no cutting force, the advantages of small thermal impact, to ensure the original accuracy of the workpiece.


2. The spatial and temporal control of the laser is very good, and the degree of freedom of the material quality, shape, size and processing environment of the processing object is very large, which is especially suitable for automated processing and special surface processing.


3. Laser marking machine marking engraving fine, the line can reach the millimeter to micron level, the use of laser marking technology produced by the marking imitation and change are very difficult, the product anti-counterfeiting is extremely important.


4. Laser processing system combined with computer numerical control technology can constitute a high-efficiency automated processing equipment, can play a variety of text, symbols and patterns, easy to use software design marking pattern, change the marking site content, to adapt to modern production efficiency, fast-paced requirements.


Laser marking of the actual application of the scene:

1. Marking of instrument panel components

Laser marking in the dashboard application is mainly on the need to translucent pattern laser marking, so that the surface of the masking ink detachment, marking characters through the light-emitting diode light, as long as the bottom of the light is on, at any time can be clearly seen on the surface of the pattern, and marking, and is not easy to wear and tear. Through the laser marking machine using high energy density laser on the workpiece for local irradiation, so that the surface material chemical reaction, thus leaving a sex marking method. Laser marking can hit a variety of text, symbols and patterns, etc., the character size can be from millimeters to micron scale, which is of special significance to the anti-counterfeiting of products.


2. Tire marking

Used for various non-metallic materials surface marking words, two-dimensional code, LOGO, etc., such as: rubber, plastic, acrylic, fabric leather, paper products and so on. Through the non-contact laser marking, high-temperature laser beam focused on the surface of rubber tires, marking out a variety of complex graphic patterns. Marking clear and beautiful, marking speed, high efficiency, is now generally popular for rubber tire marking equipment. At the same time, according to the needs of optional automation devices, to achieve automatic loading and unloading of automobile tires, positive and negative double-sided marking and other processes, by the automobile manufacturers love.


3. Labeling / nameplate marking

Applied to a variety of automotive label marking, can be widely used in a variety of materials labeling, and efficient laser marking process can fully meet the production requirements. Contents such as enterprise code, product model, year and month code, running number and special symbols can be freely adjusted.


4.Other automotive metal and non-metal marking

Modern compact cars are assembled from more than 10,000 parts, which are made of a wide variety of materials, including steel, light alloys, plastics, composites, natural fibers and so on. Many of these materials need to be uniquely marked for quality assurance and product traceability reasons. These markings must outlast the life of the vehicle and not fade even when exposed to oil, fuel or high temperatures.


Samples of laser marking machine applications in the automotive industry - Suntop


Lasers can apply permanent, high-contrast markings to most materials used in automobiles. Laser marking machines can be used either as a stand-alone mass-production marking solution for marking small parts or fully integrated into production lines. Flexible software control programs allow customization of any kind of marking content.
