CO₂ Laser Marking

CO₂ laser marking machines are renowned for their versatility and precision across many applications. Suitable for numerous applications, their ability to mark a wide range of materials, including plastics, glass, and paper, is helpful.

Another benefit of a CO₂ laser marker is its permanence. High-energy CO₂ laser beams produce long-lasting, readable markings that are immune to fading, abrasion, and corrosion. These durable markings are crucial for applications where adherence to stringent traceability and identification standards is necessary.

Also, CO₂ laser marking is a non-contact process, which means there’s minimal wear on the machine and the materials being marked. This feature decreases both material waste and maintenance costs. If these benefits weren't enough, the rapid performance of CO₂ laser etching machines also increases output and improves manufacturing operations' efficiency.

CO₂ laser marking devices from KEYENCE have produced notable benefits for a number of industries. Healthcare, consumer goods, automotive, and electronics, for example, have all seen the benefits of using these machines. For traceability, parts in the automotive industry are marked with barcodes and serial numbers. CO₂ laser marking is used in electronics to precisely mark circuit boards and other components so that they can survive in challenging conditions.

Permanently marking medical equipment and packaging is another use case. Medical devices and packaging must comply with regulatory requirements, and a CO₂ laser etching machine can assist. Consumer goods manufacturers use a CO₂ marking machine for branding and customizing products, enhancing their market appeal.

Instrumental in the packaging industry, CO₂ laser machines provide high-quality marks on cardboard and plastic packaging materials that convey important product information. Manufacturers enjoy their ability to mark quickly and accurately, which works well in high-speed production environments.

CO₂ laser markers rely on heat to mark parts, making them perfect for cutting applications. In fact, CO₂ lasers are commonly used for cutting holds, gate cutting, and sticker half-cutting applications.

Compared to mechanical cutting tools, CO₂ laser markers are fully automatable, flexible, and almost entirely maintenance-free.

Synthetic rubber has high heat and chemical resistance properties, meaning some marking methods are not strong enough to mark it. However, CO₂ laser marking has very high heat absorption, allowing it to etch marks onto synthetic rubber.

CO₂ laser marking synthetic rubber applications:

• Wiper blades
• Rubber gloves
• Car tires
• Belts

Glass has high heat resistance and is commonly transparent. Standard Fiber wavelength systems are unable to interact with glass due to these properties; however, incorporating a CO₂ laser makes the marking process seamless. CO₂ lasers engrave white marks into glass by gently generating tiny cracks, micro-fractures, using low power. The micro-fractures make up the mark or design.

CO₂ laser marking glass applications:

• Windowpane
• Bottle
• Jar
• Drinkware

Using a CO₂ laser for cardboard and wood marking ensures permanent marks that never smudge. The CO₂ laser burns designs, logos, barcodes, or characters onto the wood or cardboard surface. CO₂ laser marking is used for either white marking or dark marking.

CO₂ laser marking cardboard and wood applications:

• Drink carton
• Decorative wood sign
• Shipping box

Implementing CO₂ laser marking in your production line can significantly boost operational efficiency. These machines streamline the manufacturing process with their fast marking speeds by reducing the time needed for product identification and branding.

When KEYENCE laser markers are integrated with automated systems, the operation is seamless, minimizing manual intervention and the risk of human error. This increases throughput and marking consistency, both of which are essential for upholding production quality standards.

CO₂ laser etching machines are also flexible, so they can easily adapt to different marking tasks without requiring extensive setup changes. Due to this adaptability, manufacturers can respond quickly to changing production needs without sacrificing quality or speed.
