What is a laser marking machine? How many categories are there? What are the applications?
Laser marking machine is a device that uses a laser beam to accurately mark the surface of materials. It can create high-quality product identification on different material surfaces, such as product serial numbers, QR codes, CE/UL compliance symbols, for easy product identification, traceability, and aesthetic purposes.
1、 The working principle of laser marking machIts working principle is that the laser focuses on the target surface with high energy,
which can cause local evaporation of the material surface, exposing deep substances, or leaving clear and visible marks by changing the chemical and physical properties of surface substances.ine and laser marking machine use laser beam to form permanent marks on the surface of materials.
Laser light sources are typically fast-moving beams that can mark content such as letters, text, graphics, or barcodes.
Compared with other marking techniques, laser marking can persist on various materials and has a fast marking speed, making it suitable for large-scale production. Some laser marking machines can also precisely control the depth and effect of marking, achieving more precise marking.
2、 How many types of laser marking machines are there? What are the applications?
Laser marking machines are mainly divided into the following categories according to the type of laser:
1. Fiber laser marking machine:
Mainly used for marking metal materials such as stainless steel, aluminum, copper, etc. Fiber laser marking machine has high efficiency and precision,
and can achieve high contrast and depth marking on metal surfaces. Due to its long service life and low maintenance costs,
fiber laser marking machines are widely used for marking metal parts in industries such as electronics, automotive, and aerospace.
2. Carbon dioxide (CO2) laser marking machine:
Suitable for marking non-metallic materials such as wood, paper, plastic, leather, glass, etc.
The carbon dioxide industrial laser marking machine adopts the mainstream wavelength of CO2 laser marking equipment,
with wide applicability, good marking effect, and simple operation.
It is widely used for product identification and compliance information marking in various industries such as hardware, food, beverage, medical, tobacco, daily chemical, household appliances, etc.
Mainly used for high-precision and refined marking, especially suitable for marking on high demand materials such as plastic, glass, ceramics, etc.
The UV industrial laser marking machine adopts a small spot and high-quality laser beam, with an extremely low heat affected zone,
and can achieve extremely small marking sizes, such as high-density DM QR codes, micro characters,
and technical parameter markings, making it the first choice equipment for ultra-fine marking and special material marking.
The small laser marking machine has stable performance, fast coding speed, clear marking effect, touch screen operation, and can be flexibly integrated into the production line.
By working synchronously with other production equipment (such as assembly lines, packaging equipment, etc.),
it achieves fully automated production processes and is widely used in consumer electronics,
mobile phone parts, precision instruments, electronic components, medical devices, jewelry engraving, and pharmaceutical packaging fields.
In addition, the equipment can be flexibly adjusted to meet the needs of different products and production lines through different laser power,
focal length, and marking speed settings.
