A Guide to Fiber, CO2, and UV Laser Marking Machines: Types, Features, and Applications

A laser marking machine is a device that uses a laser beam to create precise markings on material surfaces. It can produce high-quality product identifiers such as serial numbers, QR codes, and compliance symbols (CE/UL), facilitating product identification, traceability, and enhancing aesthetic appeal.

How Does a Laser Marking Machine Work?

A laser machine for marking creates permanent markings on a material's surface by focusing a high-energy laser beam. This process can cause localized evaporation of the material's surface, exposing deeper layers, or it can alter the chemical and physical properties of the surface material to leave a clearly visible mark.

The laser source typically moves rapidly, allowing for the marking of letters, text, graphics, or barcodes.

Compared to other coding and marking technologies, laser markers provide durable markings on various materials and operate at high speeds, making them suitable for mass production. Some industrial laser marking machines can even precisely control the depth and effect of the marking, enabling more intricate designs.

Types of Laser Marking Machines and Their Applications

Laser machines for marking can be categorized primarily by the type of laser used:

1. Fiber Laser Marking Machine

Primarily used for marking metal materials like stainless steel, aluminum, and copper.

Fiber laser marking machines deliver high efficiency and precision, producing deep, high-contrast marks on metal surfaces. Known for their long lifespan and low maintenance costs, these metal laser marking machines are widely utilized in industries like electronics, automotive, and aerospace.

2. CO2 Laser Marking Machine

Suitable for marking non-metallic materials such as wood, paper, plastic, leather, and glass.

The HPRT LC401 CO2 laser marking machine is recommended for its mainstream wavelength and versatility, producing excellent marking results with simple operation.

This industrial laser marker It is widely used across various industries, including hardware, food, beverages, medical, tobacco, daily chemicals, and home appliances for product identification and compliance.

3. UV Laser Marking Machine

Primarily used for high-precision and fine marking, particularly for demanding materials like plastics, glass, and ceramics.

The HPRT LU51 UV laser marking machine employs a high-quality, small-diameter laser beam with minimal heat-affected zones. It excels in ultra-fine markings such as high-density DM barcodes, micro-characters, and technical parameters. This makes it the preferred choice for ultra-fine marking and specialized material marking.

This glass laser marking machine is stable, fast, and produces clear markings. It features a touchscreen interface for easy operation and can be seamlessly integrated into production lines, working in sync with other production equipment (such as assembly lines and packaging machines) to achieve fully automated production processes.

It is widely applied in fields such as consumer electronics, mobile parts, precision instruments, electronic components, medical devices, jewelry engraving, and pharmaceutical packaging.

Additionally, the HPRT LU51 can be flexibly adjusted through different laser powers, focal lengths, and marking speeds to meet the diverse needs of various products and production lines.
