Its use in automobile windshields and building security windows is becoming more and more common. Laser cutting technology can precisely cut laminated glass to ensure its structural integrity and aesthetic appeal.

4. Art glass

Art glass is favored for its unique appearance and design, and is widely used in interior decoration and art production. Laser cutting technology can achieve complex patterns and meticulous craftsmanship to meet the needs of artists and designers, giving the glass works more creativity and personalization.

III. Main Ways of Glass Cutting and Comparison

In the glass processing industry, the choice of cutting method has a direct impact on production efficiency and quality of finished products. The following are several major cutting methods and their comparison:

1. Mechanical cutting

Mechanical cutting is the most traditional cutting method, using a knife to scribe a line on the surface of the glass, and then break along the scribed line. Although this method has simple equipment and low cost, it has obvious shortcomings in cutting accuracy, surface smoothness and material utilization.

Advantages and Disadvantages:

- Advantages:

o Low cost and suitable for small-scale production.

o Simple equipment maintenance.

- Disadvantages:

o Lower cutting precision, difficult to handle complex shapes.

o It is easy to cause glass edge breakage, which affects the aesthetics.

2. Waterjet cutting

Waterjet cutting uses high-pressure water flow and abrasive cutting, which can realize high cutting precision and is suitable for handling various materials, including metal and glass. This method is characterized by a smooth cutting surface and is particularly suitable for cutting complex shapes.

Advantages and Disadvantages:

- Advantages:

o Smooth cutting surface with virtually no heat-affected zone.

o Can handle a wide range of materials and is suitable for a wide range of applications.

- Disadvantages:

o Higher equipment costs and high operating costs.

o Relatively slow speed and limited productivity.

3. Laser cutting

Laser cutting is currently the most advanced cutting technology, through the high-energy laser beam on the material to carry out accurate cutting, with very high cutting speed and precision. Laser cutting is suitable for a wide range of thicknesses and types of glass and is capable of handling complex patterns.

Advantages and Disadvantages:

- Advantages:

o High accuracy and efficiency for mass production.

o No contact during the cutting process, reducing physical damage to the material.

o Flexibility, allowing cutting parameters to be quickly adjusted to suit different needs.

- Disadvantages:

o Higher initial equipment investment.

o Higher technical requirements for operators.

IV. Principle and Advantages of Glass Laser Cutting

1. Basic principle of laser cutting

The principle of glass laser cutting is based on the high energy density of the laser beam. When the laser beam irradiates the glass surface, the laser energy will be rapidly absorbed by the glass, resulting in a sharp rise in temperature. The heat of the laser beam causes the glass to melt or evaporate in an instant, forming the cutting line. Subsequently, the molten material is blown away by an auxiliary gas (e.g. nitrogen or oxygen), resulting in high-precision cutting.

2. Technical parameters of laser cutting

During the laser cutting process, several key technical parameters directly affect the cutting effect:

- Laser power: the higher the power, the faster the cutting speed, but may also lead to excessive thermal effects.

- Cutting speed: too fast may lead to incomplete cutting, while too slow may lead to material overheating.

- Focal length: Adjustment of the focal position can affect the accuracy and quality of the cut.

- Gas pressure: the pressure of the auxiliary gas can affect the removal of molten material.

3. Advantages of laser cutting

- High precision: laser cutting technology can achieve micron-level cutting accuracy to meet the needs of high-end products.

- Fast cutting speed: laser cutting is relatively fast, which significantly improves the production efficiency and reduces the production cycle.

- Strong material adaptability: Whether it is thin glass or thick glass, laser cutting can be competent, and can flexibly cut various shapes and patterns.

- Non-contact processing: laser cutting is non-contact processing, does not cause mechanical stress on the material, reducing the risk of physical damage and breakage.

- Environmental protection: laser cutting process is almost no waste generated, reducing the burden on the environment.

V. Application Cases of Laser Cutting in Various Industries

1. Construction industry

In the construction industry, glass, as an important building material, is widely used in curtain walls, windows and partitions.

For example, the glass curtain walls of some high-grade office buildings adopt laser cutting technology, which ensures the accuracy of size and diversity of shapes.

2. Automobile industry

The automotive industry has extremely strict requirements for glass, especially windshield and side window glass. Laser cutting technology can realize high-precision cutting in the production of tempered glass, which improves the safety and comfort of automobiles. Modern automotive design tends to use large areas of glass, and the flexibility of laser cutting allows designers to create a more visually appealing appearance.

3. Electronics industry

In the electronics industry, glass is widely used in displays and touch screens. Laser cutting enables the cutting of extremely small sizes and complex patterns, ensuring high quality and precision in displays. With the development of 5G and smart devices, the demand for glass cutting technology will further increase.
