Mold Cleaning Is a Critical Step

As global tire production continues to grow and manufacturing technology advances, the cleaning and maintenance of tire molds have become crucial for ensuring product quality and improving production efficiency. As core components in the vulcanization process, mold cleanliness directly impacts tire appearance, dimensional accuracy, and structural integrity. Traditionally, tire manufacturers rely on chemical soaking or sandblasting for mold cleaning. These methods require the molds to be removed from the vulcanization machine, cooled, transported, cleaned, dried, and reassembled—a lengthy and labor-intensive process that poses safety and environmental risks. With "intelligent manufacturing" and "green production" becoming industry priorities, manufacturers are urgently seeking ways to improve cleaning efficiency while reducing energy consumption and mold damage.

Conventional Methods Are Inefficient and Costly

The limitations of traditional cleaning processes have become increasingly evident. Mold disassembly and cleaning result in prolonged downtime of the vulcanization machine, severely affecting production cycles and equipment utilization. Frequent disassembly also risks damaging mold edges or causing misalignment, which can compromise tire quality. Furthermore, sandblasting and chemical methods pose environmental hazards and expose workers to harmful substances under high labor intensity. Additionally, high-temperature molds must be cooled before cleaning and reheated afterward, leading to excessive energy use and low efficiency. As the dual-carbon strategy progresses, such high-energy, high-pollution, and labor-dependent approaches are clearly unsustainable in a market demanding efficiency, intelligence, and sustainability.

HGTECH’s Laser Equipment: Efficient and Eco-Friendly

In response to these challenges, HGTECH has launched its Intelligent Online Laser Cleaning Equipment for Tire Molds, offering a breakthrough solution that enables fast, high-temperature, non-disassembly cleaning directly on the vulcanization line. The system integrates a high-power laser, intelligent cleaning head, 3D machine vision, electric transfer vehicle, and fume extraction module. By directing laser beams to instantly remove surface contaminants, it can clean an entire mold in as little as 45 minutes—without any chemicals, making it safe, efficient, and eco-friendly. The system automatically identifies the mold type and centers the cleaning head with high precision. Laser radar and obstacle avoidance algorithms allow smooth movement between vulcanization machines, while end-of-arm collision sensors ensure operational safety for both equipment and personnel. During cleaning, fume and particles are captured and filtered in real time, maintaining a clean work environment. HGTECH’s solution significantly reduces machine downtime, enhances cleaning quality, and prolongs mold life. By delivering a smart, green, and high-efficiency process, it ushers in a new era of mold maintenance for the tire industry.
