Tire vulcanization molds operate continuously under high-temperature vulcanization conditions, causing rubber carbon deposits, stubborn adhesive residues, oxide layers, and oil contamination to readily accumulate on the mold cavity, tread blocks, and side plates. This directly results in flash, blurred tread patterns, poor surface appearance, and a decline in first‑pass yield.

Traditional sandblasting, manual polishing, and chemical cleaning processes all have significant drawbacks: they leave numerous dead‑zone residues, deliver uneven cleanliness, and can easily damage the mold’s fine surface textures and substrate precision. Moreover, these methods are time‑consuming to maintain, incur high labor costs, and cause severe environmental pollution. Prolonged shutdowns for maintenance severely constrain production efficiency, making them a pervasive core pain point across the tire manufacturing industry.
 

To address the challenges of tire‑mold maintenance and repair, Horizon Laser Technology has developed an integrated solution that combines laser cutting, marking, welding, and cleaning. This one‑stop system meets the full spectrum of needs—cleaning and refurbishing tire molds, repairing defects, trimming components, and managing traceability—while fully replacing conventional, labor‑intensive maintenance practices. The solution features a range of dedicated offline intelligent cleaning workstations, including versatile dual‑station models, specialized tread‑block units, and side‑plate‑specific systems, compatible with all‑steel and semi‑steel tire molds.
 

The equipment features a same-side, dual-station configuration with in‑line loading and unloading, paired with a dual 3D vision system. This setup enables sealed cleaning at Station 1 while simultaneously performing loading and unloading at Station 2, allowing for alternating operations that maximize production efficiency and significantly reduce mold downtime.
 

The complete system supports one‑button, fully automated operation: after automatic material loading, 3D vision scanning generates a customized three‑dimensional cleaning path, eliminating the need to input tire‑size specifications. Equipped with a dedicated cleaning head, the robot delivers precision cleaning with no dead zones. Leveraging a proprietary galvanometer‑based flying‑beam cleaning algorithm, operational efficiency is improved by 30%–50%. Paired with a flat‑top laser spot and high single‑pulse energy, it delivers powerful stain removal while selectively stripping away contaminants without damaging the mold substrate or its delicate surface textures.
 

The pattern‑block model supports multi‑workpiece cyclic cleaning and offers optional 3D vision and laser‑range‑based dual‑positioning solutions, with a compact, space‑saving design. The side‑panel‑specific model features dual red‑light precision positioning and a dual‑action purification system—blowing air combined with vacuum suction—for more thorough cleaning. A fully enclosed dust‑extraction design centrally captures process fumes and particulates, enabling green, pollution‑free production. Additionally, it can be paired with laser welding to repair mold wear and defects, and with laser marking for mold maintenance and traceability, ensuring a stable, unified process that meets the demands of high‑precision mass‑production and ongoing upkeep.
 

Currently, this solution has been widely implemented across major tire manufacturers, supporting the refurbishment and repair of vulcanization molds that undergo long-term, high‑frequency use. It effectively addresses the shortcomings of conventional methods—such as mold damage, low efficiency, and significant environmental pollution—while substantially reducing mold maintenance and replacement costs, improving first‑pass yield, and helping tire companies achieve intelligent, green upgrades in mold maintenance and management.
