Laser Marking Applications

Laser Marking

Laser marking can be used for marking or processing various types of materials. There are also several different marking and processing methods. Due to the varying capabilities and features of laser marking technologies, this inherently leads to many different applications. However, the appropriate laser marking system and peripheral equipment vary depending on the material and desired marking or processing method. The laser light being used can also vary. This section introduces the basic knowledge required for performing laser marking.

Laser Engraving

Laser engraving has been utilised for decades, as many businesses and industries rely on the technology for various applications. The process of engraving logos, text, barcodes, and other identifying marks is used on metal, wood, acrylic, glass, leather, cardboard, and more. Although the versatility of laser engraving is attractive for many, there are some drawbacks and disadvantages that should be carefully considered. To help you make an informed decision for your particular needs, we’ll take a look at those considerations and common engraving applications. We will also discuss the characteristics of laser engraving versus other methods, such as laser marking, as well as the best machines for the job.

Laser Etching

Laser etching machines are revolutionary tools that open up amazing possibilities in creating, crafting, and even manufacturing objects with highly intricate and detailed designs. By harnessing the power of laser technology, many industries are transforming a wide variety of materials, ranging from organic products like wood to metals, into breathtaking pieces of art or useful industrial products. In the following, we will learn about laser etching machines, the materials used, common laser etching applications, and the types of laser etching solutions KEYENCE provides to help improve processes.

Laser Annealing

Laser annealing is a common marking method that uses a powerful laser to create controlled heat on the surface of a material. Unlike traditional engraving which removes the surface’s material, laser annealing changes the surface colour, without removing or damaging any material. This creates a permanent, high-contrast mark that is resistant to fading. In addition, it does not engrave deep or raise the surface layer, so this works well on parts that need to remain extremely smooth. Because of these features and benefits, many industries, such as the medical and aerospace industries, utilise a laser annealing process for its precision and durable marking abilities. So, let’s take a deeper look at laser annealing and how it is being utilised in the medical and aerospace industries specifically.

Laser Labelling

Laser labelling is the process of using a laser marking machine to put a label on a product. The label can be used for traceability, identification, or adding regulatory information. Replacing a labeller with a laser can have benefits across many aspects of production. Using a laser marking machine rather than a standard inkjet printer for labelling will improve value with time, money, and production. Laser markers decrease production time, increase permanency of labels, and decrease use of extra materials. In addition, manufacturers using laser markers don’t have to deal with consumables such as physical labels, adhesives, or industrial ink. Laser labelling machines are a versatile innovation in the labelling world that can help reduce waste pollution, various costs, and a long list of other benefits, ranging from the manufacturers to the end consumer and even the environment. Below, we will discuss the differences between laser marking and standard labelling, the characteristics of each, and the best machines to use.

Laser Processing

Laser Cleaning

Laser cleaning has been a proven technology for many manufacturers. For years, this process has been helping to remove dust, rust, and imperfections from a variety of surfaces. This cost-effective and efficient solution uses specialised machines, provides many benefits, and can be seen across a number of applications.

Laser Rust Removal

No one likes rust—whether that be because it ruins colours, decreases magnetic attraction, weakens structures, or adds unwanted friction—and manufacturers would do away with it entirely if they could. However, rust is a naturally occurring corrosion process caused by water and oxygen exposure to iron or steel. Because of this, it is almost impossible to avoid.

Laser Oxide Removal

Oxidation is the naturally occurring surface change created by metal’s interaction with oxygen. Oxidised metal signifies the first step in corrosion and is not aesthetically pleasing. Additionally, the oxidised surface is incompatible with other processing methods like welding, moulding, and extruding because it is not a clean and workable surface area. Although it is not super harmful, it is not preferred and often requires removal. Fortunately, there is a solution. Conducting laser oxide removal is a precise and efficient method for combatting the inconvenience of oxidation. In the following, we will discuss the ins and outs of KEYENCE’s laser oxide removal methods.

Laser Ablation

Laser ablation is the process of heating a surface to its ablation point so the top layer vaporises. Lasers achieve this by using a short pulse laser with high power, which ensures that only the top layer is targeted and there is no effect on the substrate. Industrial laser ablation is a non-damaging and resourceful marking and surface removal process that can be used for many applications.

Laser Texturing

A texture is a pattern formed on a surface that changes the material's appearance. Laser texturing is one process that helps manufacturers alter these surfaces to achieve a desired look. There are many ways to add texture to a material, but laser technology is an efficient, environmentally friendly, and biocompatible choice for adding texture to a surface. It uses a laser marking machine to texture metals, ceramics, and plastic. Originally, lasers were used for texturing to enhance friction, aesthetics, adhesion, and conductivity, a purpose that remains relevant. However, laser texturing has now expanded its applications to the medical field due to its biocompatibility.

Laser Cutting

Laser cutting is gaining popularity as the strength of a laser is more efficient and creates cleaner cuts than a non-laser cutting machine. Laser cutting can be done using a laser marker. Learn about laser cutting, the process that uses laser light to cut a target, through various marking examples.

Laser Paint Removal

Laser paint removal technology has continued to emerge in recent years as it offers limitless possibilities and can be used in a myriad of applications. For example, laser marking paint removal can quickly and effectively remove layers of paint or plating from plastics, metals, and other surfaces. This process is an incredibly useful tool for those in the automotive, aerospace, agriculture, construction, and manufacturing industries. These industries use laser paint removal for a variety of parts and materials for numerous reasons. Let’s take a closer look at the benefits they provide.

Laser Bonding

Laser bonding brings several unique benefits to manufacturing. Its goal is to create seamless permanent marks on a wide range of surfaces. The practice is commonly applied to ceramics, various metals, and even stone. The technology promises multifaceted capability and unmatched efficiency, from product serialisation to intricate labels and more. In this article, we’ll review prominent laser bonding applications and other relevant information about the technology’s design.

Laser Drilling

Laser drilling is a process that uses a laser beam to create precise holes in a variety of materials across industries like automotive, semiconductor, food/beverage, medical devices, and electric vehicles. Within these industries, laser-drilled holes are utilised for a range of processing goals.
