In overseas markets, laser cleaning systems have long been deployed on a large scale in the aerospace industry. Throughout an aircraft’s service life, periodic repainting is required, and the thorough removal of old paint coatings is a critical maintenance step. Conventional mechanical sandblasting for paint removal can easily scratch the aircraft’s metallic skin, creating potential safety hazards; in contrast, laser cleaning equipment can strip paint from an entire airframe in a matter of hours—e.g., removing the fuselage’s paint layer in just two days—without damaging the underlying structure, delivering both safety and efficiency.

Aerospace components are subject to stringent structural‑strength requirements. Prior to welding, laser cleaning is used to remove oxide layers, oil, and other contaminants from the joint area, thereby preventing porosity and slag inclusions in the weld and significantly enhancing weld strength. After welding, laser cleaning further eliminates surface scale from the weld, improving its appearance and ensuring the reliability of aerospace components.
 

Traditional sandblasting and chemical paint removal suffer from drawbacks such as substrate damage, significant environmental pollution, and high hazardous‑waste disposal costs. Laser‑based non‑contact cleaning, by contrast, perfectly meets the non‑destructive, environmentally friendly requirements of advanced aerospace manufacturing.

Beyond the aerospace sector, laser cleaning also delivers significant value in shipbuilding and logistics‑equipment industries. Ships are exposed for extended periods to the high‑salt, high‑humidity marine environment, making steel plates, decks, and welds highly susceptible to corrosion. Conventional sandblasting generates substantial dust and can easily cause microscopic surface damage to the steel.

Laser cleaning can be used for pre‑welding surface preparation of steel plates, removal of oxide scale from welds, and stripping of old paint and rust layers from ship hulls. It also enables precise treatment of complex welds and hard‑to‑reach corners and edges. The cleaned surfaces meet coating‑process standards, are well suited to on‑site dock operations, reduce the generation of hazardous waste, and align with the green shipbuilding development goals of COSCO SHIPPING Heavy Industry…
 

The logistics equipment industry encompasses a wide range of metal components, including warehouse racking, shipping containers, heavy‑duty steel structures, and material handling equipment. During the manufacturing phase, removing oxide layers prior to welding enhances weld quality. In subsequent equipment maintenance, laser cleaning efficiently eliminates rust, old coatings, and oil residues without requiring component disassembly; handheld models offer flexible on‑site operation in workshops or outdoor environments, replacing traditional grinding and acid‑pickling processes and reducing overall operation and maintenance costs.

The Horizon pulsed laser cleaning system employs a non-contact processing mode, enabling precise control of the cleaning depth. It removes only rust, paint layers, and oxide films while safeguarding the substrate, with no chemical agents, minimal dust generation, and zero consumables. It seamlessly balances handheld flexibility with automated integration. One single unit can handle multiple processes—including pre-weld preparation, post-weld seam cleaning, removal of old coatings, and rust removal and refurbishment—making it suitable for diverse industries such as aerospace, shipbuilding, and logistics equipment.

In response to the growing demand for green upgrades in high-end manufacturing and heavy industry, laser cleaning is gradually replacing traditional, highly polluting processes. Horizon Laser Technology offers prototype testing and customized process solutions, helping enterprises enhance quality and efficiency while transitioning to sustainable, eco‑friendly production.
