What Materials Can Laser Marking Machines Be Applied To?

Laser marking technology is an advanced process that uses high-energy laser beams to mark the surface of objects. It achieves precise and lasting markings by changing the surface properties of the material. Compared with traditional marking methods, laser marking has significant advantages such as no contact, no consumables, high definition, wear resistance and environmental protection. This makes it gradually become an important tool for enterprises to improve efficiency and competitiveness in fields such as industrial manufacturing, brand promotion and product traceability.

Laser marking machines are widely used in many fields, including manufacturing (such as metal parts, electronic products), packaging industry (such as plastic containers, cartons), medical field (such as medical equipment, drug labeling), aerospace, automotive industry and Consumer products (such as watches, jewelry, etc.), etc. With its flexibility and versatility, laser marking technology is recognized by more and more industries and has become an important means to enhance product added value and maintain brand image.

Laser marking technology uses a high-energy laser beam to irradiate the surface of a material. The energy of the laser instantly heats, vaporizes or discolors the material, thereby forming a permanent mark on the surface. The process includes laser emission, focused irradiation, material interaction, and mark formation. The specific steps are as follows:

Laser generation: The laser emits a high-energy laser beam.

Focusing: The laser beam is focused onto the surface of the material through an optical system to form a point with high energy density.

Irradiating the material: The focused laser beam is irradiated onto the material, locally heating it.

Material reaction: The material vaporizes, melts or discolors due to thermal energy, forming the desired mark.

Pattern formation: The laser moves along a preset path to engrave text, patterns or barcodes on the material.

Through these steps, laser marking technology can achieve high-precision, durable and high-quality marking, and is widely used in industry, medical care, electronics, food and other fields.

Laser marking technology can be divided into several main types according to the type of laser used and the application scenario. The following is a detailed introduction to different types of laser marking technology:
