Why choose laser marking machine?

Laser marking is the process of marking materials with a laser beam with a small spot diameter. It is widely used for marking on various materials, such as trademarks, shelf life, serial numbers, etc. So what features do the laser marking machines have? Why should we choose laser marking machines instead of traditional machines?This article gives an answer.

The following knowledge points are listed below:

The traditional methods of marking

The advantages of laser marking machine comparing to traditional machine

1.  The traditional methods of marking

There are many marking methods to choose from, considering the material to be marked, cost, marking conditions, etc.

The main marking methods are as follows:

Inkjet printing

Shot a tiny stream of ink particles, marked with dots. Inkjet printers used with personal computers and industrial printers that mark the best dates on laminated films are the main applications.

Ink stamping

The letterpress or gravure supplied with ink is pressed against the object as a mark. This is the most popular method in the past. Although the equipment is cheap, it runs at a high cost; in addition, it needs to control the ink.

Punching

Press a numbered head on the object, and marking the required symbols such as letters and characters on it. This is a widely accepted metal mark. Although this method is very reliable and durable, it is less efficient and requires a lot of time to change the head.

2. The advantages of laser marking machine comparing to traditional machine

Laser marking machine uses precision spot laser to directly mark on metal, plastic and other materials. Laser markers engrave, anneal, evaporate or remove the surface of the material by moving the laser spot to produce a clear mark. No ink is required.

Advantages of laser marking

Environmentally friendly and easy to recycle.

Unlike ink-based markings, no solvents are required. Because no ink adheres to the substrate, it is easy to recycle. Laser marking machine generally does not require post-processing, which greatly reduces the production process.

Mark is not erasable

The laser produces contrast, high-quality marks that never wear out, unlike the way ink is used. This mark complies with the quality control requirements of PL law and ISO international standards.

Good mark

Laser marking machines can do fine marking, but inkjet marking can never do that. Laser marking machine is the best choice for marking microelectronic parts.

Easy to design and change tag content

Marking software is easy to use, so markups can be designed easily and you can easily switch to other marks on your PC. Laser marking is even applicable to many products produced in small batches.

Increase productivity and save labor

High-speed marking helps increase productivity. Easy maintenance saves labor. The production line is highly automated and unmanned at night.

Extensive laser marking materials

Various materials such as plastics, ceramics, semiconductors, paper, and glass can be accepted. In addition, Laser marking machine can also accept materials with an oil film, which is difficult to inkjet mark in the oil film.

No contact of the material

Any process using a laser beam is a non-contact process, which means that the laser beam does not physically interact with the material to which it is directed. Therefore, it only affects the heated area and does not cause any abrasion or damage to the surrounding area of the material.

No stripping away the surface of the material

Laser marking machine does not take away any material and it works unlike other processes such as laser engraving. Instead, it heats up the target area, causing oxidation. This in turn will cause a color change beneath the surface of the material, leaving permanent marks.

So, comparing to traditional way of marking, the laser marking machines have so many advantages, why not choose them? We also produce Laser Engraving Machine, Laser Cutting Machine.
