Keyence UV Laser Marking Systems
KEYENCE’s UV laser markers utilize groundbreaking technology to create crisp, enduring marks on products. These devices use a 355 nm wavelength and execute a “cold marking” process that etches with minimal thermal impact, safeguarding material integrity.
They also enable medical manufacturers to mark anything from PE medication bottles to implantable devices with traceability codes that both machines and humans can read.
Cost-effective
UV laser marking machines are a cost-effective solution for a range of applications. This technology uses a shorter wavelength than standard fibre lasers to produce high-contrast marks on a variety of materials. It also requires less power, reducing operating costs and maintenance expenses. The machine can mark logos, symbols, bar codes and text, as well as a wide range of other formats.
The short wavelength allows UV lasers to interact with atomic bonds and break them without vaporising or melting the material. This reduces the heat-affected zone and creates a more durable mark. This makes it ideal for applications that require a low heat exposure, such as medical devices or electronic products.
The system also offers precise and accurate marking for plastic, resin, glass and various metals. It can produce clear, readable markings and is ideal for traceability codes. It also offers quick setup and a 7-inch LCD touch screen for easy operation. The system’s hermetically sealed diode lasts up to 20,000 hours and is maintenance free. It is also energy efficient and can run for a long time with a low average power.
Versatile
A UV laser marking machine can mark many types of materials. It is an ideal choice for companies with a wide range of applications. Its high-quality pulses minimize thermal effects and can mark uv laser marking system nonsymmetrical, cylindrical and spherical surfaces without dross, yellow tinting or burrs.
The machine uses focusing optics to concentrate the laser energy into a tight spot. This allows it to mark a variety of products, including metals and plastics. The UV laser’s short wavelength also means that it causes minimal heat damage to the material. This makes it a good choice for temperature-sensitive applications, such as electronics, aerospace, medical, and automotive.
The laser can mark a wide variety of text, graphics and barcodes on the surface of the product. It can also produce tamperproof and secure marks on the packaging of food, drugs, and other products. It can even mark 3D portraits inside a glass crystal. The markings can be engraved in either the surface or subsurface of the product. The marks are durable and can withstand repeated use, making them a great option for brands that want to protect their products.
Energy-efficient
UV laser marking systems offer a precise blend of artistry and engineering for heat-sensitive materials. Using a 355 nm wavelength, they use a unique “cold marking” process to mark with minimal thermal impact, safeguarding the integrity of the material while delivering crisp and enduring marks.
The laser marking machine works by passing a uv laser marking standard laser light through a special crystal, reducing its wavelength to the ultraviolet range. This makes it safe for the majority of products, including glass, silicone and precious metals, and prevents any damage due to excessive heat stress.
KEYENCE laser markers also feature an adjustable focal point, which allows them to stay in focus on a larger field of view than traditional fiber and CO2 machines. This enables them to mark 3-dimensional shapes, such as cylinders, inclines and cones, and map to a CAD image for non-standard products.
A UV laser marker is also environmentally friendly, as it does not require inks or solvents to operate. This reduces operating costs and saves space, while also protecting workers from laser exposure. This helps businesses meet strict environmental standards and boost efficiency.
Safe
Laser marking systems use a non-contact method for marking, preventing the transfer of contaminants from your product to the machine and vice versa. Additionally, they can mark on 3D surfaces without any distortion. This makes them safe to work with for a wide variety of materials and products. In addition, they offer superior quality and consistency compared to other methods such as dot-ping and acid etching.
KEYENCE’s MD-U and MD-F series UV and fibre laser marking systems are designed to meet industry requirements. They both come with 3-Axis control for precise marking and can engrave on all types of material. They also have an auto-focused focal point that adjusts for different positions on the production line.
When using a laser engraving system, it is important to follow the guidelines and safety measures provided by your manufacturer. These will help prevent accidents and ensure your employees are protected against laser damage. For example, CO2 lasers can cause severe burns if not used correctly, so they require special protective eyewear and proper ventilation. Similarly, MOPA fibre lasers can generate toxic fumes and particulate matter, which is why they should be used in a controlled environment.
Easy to operate
UV laser markers can create precise and durable markings on a variety of materials. They are ideal for medical-grade wires and cables, catheters, and automotive components. They can even mark high-temperature materials like metals and some plastics without causing heat-related damage. The UV laser’s ability to easily mark a wide range of materials makes it the most versatile marking system on the market.
KEYENCE’s MD-U series UV laser marker uses 355nm wavelength to break down molecular bonds, creating marks that are free of distortion and heat stress. Its specialized software allows for customization and integration of marking processes into existing workflows.
This model also has the capability to mark curved surfaces. It is capable of engraving multiple heights of cylinders, inclines, cones, and spheres on objects up to 300mm in diameter. Its patented 3D camera enables the machine to map marking programs on a live image of an object, ensuring that the mark will be placed correctly and efficiently. This feature reduces time and error while increasing productivity. The machine also features a modular construction that can fit into tight spaces or environments.
