FINISHED PRODUCT EFFECT

MIRROR LASER SANDBLASTING MACHINE is an advanced device used for surface treatment of glass mirrors. It uses laser technology to achieve precise frosting, pattern engraving, and functional processing. The following is a comprehensive analysis based on its uses, functions, core principles, and mainstream laser power:

MAIN USES AND FUNCTIONS

1. Surface Frosting

Creates a uniform matte layer on the surface of a smart bathroom mirror, preventing condensation and enhancing decorative effects (such as semi-transparent textures and brand logos).

Touch Function Area Creation: Sands the touch button area of an LED mirror to achieve a backlight-transmitting effect.

2. Multifunctional Integrated Processing

Paint Stripping: Removes the back paint layer to expose the glass substrate for electronic component embedding or wiring.

Drilling: Reserves precise holes (as small as 2mm) for sensors, cameras, or lighting in smart mirrors.

Pattern Customization: Supports one-time engraving of complex textures (such as geometric shapes and simulated stone patterns) to meet personalized home needs.

3. Applications

Widely used in the processing of smart home mirrors (bathroom mirrors, vanity mirrors), building curtain walls, automotive rearview mirrors, and electronic instrument panels.

CORE WORKING PRINCIPLE

Laser sandblasting is based on the physical process of high-energy laser interaction with materials. The specific process is as follows:

1. Energy Focusing: A fiber laser (wavelength of 1064nm) emits pulsed laser light, which is reflected and focused onto the mirror surface by a galvanometer system.

2. Surface Micromelting and Rapid Cooling: The laser beam instantaneously heats a localized area of the mirror surface (to temperatures reaching thousands of degrees Celsius), causing micromelting and rapid cooling, forming an amorphous frosted texture.

3. Precision Control:

Parameter Adjustment: By adjusting the laser power, frequency, scanning speed, and line spacing, the frosting depth (typically 0.1–0.5mm) and density can be controlled.

Motion Coordination: Utilizing "galvanometer-servo axis four-axis linkage" technology, seamless processing of large-format surfaces (e.g., 3m x 6m) is achieved, eliminating the misalignment issues associated with traditional splicing.

Direct programming of any pattern

MAINSTREAM LASER POWER CONFIGURATIONS

The core of a laser sandblasting machine is a fiber laser. The power selection depends on processing requirements and efficiency:

1. Low-medium power (100–120W)

- Suitable for: Shallow sandblasting of thin mirrors (1–5mm) and fine pattern engraving.

- Features: Low cost, suitable for small and medium-sized businesses (such as custom mirrors for advertising).

- Representative model: Pioneers 100W model (operating speed 7000mm/s).

2. High Power (180–200W)

- Applications: Deep hole processing in thick glass (≤25mm), efficient paint stripping of large areas (such as full-wall bathroom mirrors).

- Features: Peak power reaches 200kW (20 times that of conventional lasers), supporting high-speed continuous operation (20㎡/h).

3. Ultra-Large Format Laser (180W + Air Flotation System)

- Applications: Architectural curtain walls, giant LED mirrors (up to 3m×6m).

- Features: Equipped with a 4kW air flotation platform, it reduces glass handling damage and improves stability.

Selection Recommendation: 120W is commonly used for smart home mirrors; models with 200W or higher are recommended for industrial-grade mass production. Pay attention to the interoperability between the laser brand (such as JPT, IPG) and the motion controller.

SUMMARY

Mirror laser sandblasting machines are gradually replacing sandblasting and chemical etching processes due to their non-contact processing, high-precision customization, and environmental friendliness. Its core technologies include:

Multi-functional integration: A single machine performs sandblasting, paint stripping, and drilling, reducing four process steps;

Large-format, traceless technology: Four-axis linkage eliminates splicing errors;

Power adaptability: 100–200W fiber lasers are the mainstream, with high-power models increasing production capacity by 2–3 times.

This equipment is a key component in smart home mirror manufacturing, particularly suited for balancing high-end customization with high-volume production.

POWER AND PROCESSING CAPACITY

120W: Suitable for glass or mirrors ≤8mm thick, with a shallow sandblasting depth (typically 0.1–0.5mm). It is ideal for decorative patterns and text engravings that require high precision but low depth.

200W: A high-power model, it can easily process glass up to 19mm thick, with sandblasting depths of 3–8mm. It also supports multifunctional composite processes such as deep engraving, paint stripping, and drilling (for example, stripping paint from touch buttons in just 3 seconds per unit).
