3C Industry应用：

In the manufacturing and retreading of rubber tires, the cleaning of rubber residues, oxide layers, and contaminants from molds and tire surfaces has always been a critical yet challenging task. Traditional methods, such as chemical cleaning, dry ice cleaning, or mechanical grinding, often suffer from drawbacks like environmental pollution, substrate damage, low efficiency, or incomplete cleaning. Today, an advanced technology that uses "light" as its tool—laser cleaning—is pioneering an innovative cleaning path in the tire industry with its unique advantages of being non-contact, non-damaging, highly efficient, and environmentally friendly. It significantly enhances production quality and sustainability.

Principle and Application Scenarios

The core principle of laser cleaning involves irradiating the surface to be cleaned with a high-energy, high-frequency pulsed laser beam. Contaminants such as rubber residues, release agents, and oil stains instantly absorb the laser energy, undergoing rapid vaporization, expansion, or instantaneous removal. Meanwhile, the substrate, such as metal molds or rubber tire bodies, remains intact due to its high reflectivity or high thermal damage threshold to specific laser wavelengths. This "selective ablation" process enables micron-level precision removal.

In the tire industry, its application focuses on two core scenarios:

Tire Mold Cleaning: Mold texture directly determines the appearance and performance of tires. Laser cleaning thoroughly and meticulously removes accumulated vulcanized rubber and release agent deposits from the fine patterns of molds, restoring their original smoothness and texture precision. This fundamentally eliminates tire appearance defects caused by mold contamination, such as burrs or insufficient rubber, while significantly extending the mold's service life.

Tire Retreading Pre-treatment: Before retreading used tires, the aged rubber layer and contaminants on the tire surface must be completely removed to ensure strong adhesion between the new vulcanized rubber and the old tire body. Laser cleaning can precisely and controllably strip away the old rubber layer, exposing a fresh, activated rubber surface without generating thermal stress that could damage the tire cord. This greatly enhances the safety and reliability of retreaded tires, serving as a vital technological support for the green circular economy.

Core Advantages and Future Prospects

Compared to traditional methods, laser cleaning offers outstanding advantages:

• Ultimate Cleanliness and Non-damage: Achieves surface cleanliness up to Sa3 grade without causing any physical damage to metal or rubber substrates, preserving the integrity of precision molds and tire structures.

• High Efficiency and Environmental Friendliness: As a "dry" cleaning method, it requires no chemical solvents or abrasives, produces no secondary waste, and consumes minimal energy, complying with stringent environmental regulations.

• High Automation and Intelligence: Easily integrated into automated production lines, it enables remote and precise control. Cleaning parameters can be digitally stored and optimized, adapting to complex surface cleaning and significantly improving production cycle times and consistency.

As laser equipment costs gradually decrease and integration levels improve, laser cleaning technology is expanding from high-end tire manufacturing to broader industry applications. It not only addresses long-standing cleaning challenges in tire manufacturing but also drives the tire industry toward high-quality, sustainable development with its green, intelligent, and precise characteristics, becoming a key indicator of advanced manufacturing capabilities. In the future, with ongoing process optimization, this "light"-based technology is poised to play an increasingly critical role in the tire industry and broader industrial cleaning fields.
