Popular HeatSign Laser Marking Machines and Products

With so many laser marking options for sale on the market, it can be challenging to pick the right marking machine for your unique purposes. Here are the most popular laser engraving machines based on different use cases:

Fiber Laser Marking Machine (1064 nm wavelength)

Fiber laser markers are the most recent development in laser marking system that uses a low-maintenance solid-state laser source. They have an effective cooling system. As a result, they are very popular among the existing laser marking systems. Furthermore, they do not require consumable materials; you don’t have to worry about maintenance. These fiber laser marking machines are ideal for marking metals such as stainless steel, aluminum, and some plastics.

UV Laser Marking Machine (0.355 µm wavelength)

UV laser marking machines use ultraviolet light, breaking the bonds holding the material surface together and leading to marking. It is a cold process, producing no peripheral heating; hence, UV laser markers are called cold lasers. As a result of the cold process, UV laser poses no risk to the target materials’ strength or thermal integrity, making them the perfect laser engraving machine or laser etching machine for delicate materials like plastics and thin latex.

UV laser systems can work at very high speeds. As a result, this reduces the cycle times for industrial operations such as marking semiconductors and plastics like PVC, ABS, Polypropylene, metals, paper, and ceramic chips.

Quick Introduction to Laser Marking Machine Mechanism

Laser marking is a non-contact process that creates readable marks by generating a visual contrast between the text and the background. Below are the several lasers marking techniques available

Laser Engraving

This method changes specular reflection because it removes material from the surface. It mostly applies to metals. There is an optimal frequency and speed so that evaporation can occur for the particular material. Lasers with short pulses and high peak power generally give the best results and are best suited for these applications.

Laser Etching (Ablation)

This method removes coating or lacquer layers from the base material. For example, the ablation of the oxide layer of anodized aluminum exposes the metal beneath it. Due to the high temperatures ablation markers produce, they heat the surface past its vaporization point. While doing no damage to the base material, this makes your marking pattern or text visible. This type of laser system is used for fine laser marker applications.

Laser Annealing

In laser annealing, the marking machine laser beam heats the surface where marks appear due to oxidation. The surface gets its colored appearance as a result of the composition and thickness of the oxide layer. It is highly applicable in stainless steel and titanium part marking

Laser Color Change

As a rule, this mechanism of marking laser systems usually processes plastics, heating them in precise spots. The heat destroys carbon on the surface, so plastics get darker (e.g., carbonization) or lighter (e.g., bleaching). The exact outcome depends on the type and composition of the plastic or polymer.

Laser color change

Laser Foaming

In this case, the laser machine beam heats the polymer to a given, so some elements begin to foam. Due to the volume change, the material bulges outward. This produces clear textured marks. This type of laser system is extremely useful for applications in products where clear marking is required.
