The Different Types of Laser Marking Machines Available Today

by Hei White Heiwhite

With the advent of plastic and laser marking systems, many industries have seen a strong demand for printing solutions. With the invention of most modern machines and technologies, technology has evolved to its extreme. There have been many applications for imprinting identification on metal surfaces and joining two metal parts that are dissimilar. Metal surfaces were difficult to print on, join metal parts to one form, and cut into small pieces in the past.

A marking job has become easier due to the evolution of technology like laser welding. Laser beams are highly penetrating enough to print on hard surfaces. Marking applications that use laser beams are a new technology that is being adopted by almost every industry today. Modern machines can be found nowadays for printing on metal surfaces and assembling metal components. There are many manufacturing industries that use laser marking machine to identify their products. Laser marking is a method of marking that allows you to make markings on both soft and hard metal surfaces.

All areas of manufacturing, industrial, and scientific technology can benefit from laser imprinting. Using laser technology for the imprinting systems, it is possible to mark and design on any surface. As an example, plastics are decorated using laser beam technology. It is said to be the most advanced and accurate method of designing that the comparable systems have many limitations in speed and accuracy. Laser mark systems are widely used and considered to be the most compact and widely used marking technology due to their speed and accuracy of marking and designing. A laser print system can be used as a fast and accurate printing machine in virtually any industry because it can make markings and designs on plastic, metals, wood, carbide, etc. Laser mark machines offer the best marking solution for metals such as silver, gold, platinum, etc.

Every engineering and manufacturing industry uses laser beam marking as a convenient method of marking. Laser technology has become the mainstay for marking and design purposes. Manufacturing companies often want to put their brand name or information on the particular product they produce on their products. It is a competitive process that many industries need to use to print a special mark or a serial number on circuit boards, chips, etc. for traceability purposes.

Laser marking machines types

It uses a laser beam to label or mark a wide range of materials. The preferred method of laser marking is based on the quality of finish required and the material. Laser marking techniques include foaming, annealing, staining, removing, and engraving. Plastics (polycarbonate and ABS), laminates, foils, and metals (copper, platinum, titanium, bronze, gold, silver, stainless steel, and platinum) are some of the most commonly used materials.

There are four major types of laser marking machines:

The engraving process

In laser engraving, the material's top surface is heated, melted, and evaporated. This method uses a laser beam to remove material quickly and efficiently. It leaves behind a clear impression of the logo, text, design, or other mark once the material has been removed.

Removing

In the process of using laser removing the uppermost layer is removed by the laser beam to create a contrast in color throughout the different layers of the material. In addition to laminates, coated metals, films, foils, and anodized aluminum, laminates and coated metals are preferred materials for this technique.

The staining

A laser staining technique uses heat generated by the laser beam to initiate a chemical reaction. This results in the possibility of creating different color shades in the material. Color shading is determined by the chemical composition of the plastic or other material. Using a laser with a light-colored plastic material, for example, will produce soot-like particles that leave dark marks. Get more info about laser rust removal, Visit our website.

Annealing marking

In this technique, laser beams are used to oxidize metal surfaces by creating an oxidation process, causing the metal to change color at different layers.

Laser marking techniques have many benefits

As a result of laser marking, there are many benefits. One of them is the ability to work with small geometries, 1-point fonts, and delicate graphics with high precision. This is a permanent process and won't fade when the material comes into contact with acids, heat, or abrasion. Furthermore, lasers are fast and efficient, which means they can help increase productivity and lower production costs.
