Laser cleaning is hailed as "the most promising green cleaning technology of the 21st century." Compared to traditional cleaning methods, laser cleaning offers significant advantages such as environmental friendliness, ease of automation, high efficiency, high precision, and non-contact processing. In recent years, it has been widely adopted in industrial production across various sectors, including automotive manufacturing, aerospace, precision electronics, medical equipment, and shipbuilding. In the fields of electric vehicle batteries, motors, electronic control systems, vehicle bodies, and automotive components, laser cleaning technology offers comprehensive application solutions.
Laser cleaning before and after welding in automobiles:
Removes contaminants such as oil stains, rust, oxide coatings (e.g., galvanized layers), and release agents from welding areas (e.g., body panels, chassis components, battery trays, etc.). Significantly improves welding quality and strength, reduces welding defects (e.g., porosity, incomplete fusion), and enhances welding yield. Pre-welding cleaning is critical. Laser cleaning removes contaminants like oil, dust, and oxide layers from welding areas, improving welding quality, reducing defects like porosity and slag inclusion, and ensuring welding strength and reliability. BMW Group case studies show this technology can boost cylinder block cleaning efficiency by 65%, precisely removing 0.1-0.3mm-thick oxide layers to reduce welding defect rates below 0.02%.
Automotive mold cleaning and maintenance:
Removes release agent residues, carbon deposits, polymer residues, and oxides from the surfaces of stamping molds, injection molding molds, casting molds, etc. Restores mold surface finish, ensures product quality (e.g., surface finish of body stamping parts), extends mold service life, and reduces downtime for maintenance.
Power Battery Manufacturing:
Electrode Sheet Cleaning: Remove oil stains and oxides from the surfaces of metal foils (copper foil, aluminum foil) before coating the positive and negative electrodes of lithium batteries to improve the adhesion of the coating slurry.
Pre-welding cleaning: Remove oxides and residual insulation layers from welding areas such as battery tabs, connection plates, and busbars to ensure welding quality and reduce contact resistance.
Sealing nail welding pre-cleaning: Clean the welding areas of battery cover sealing nails to ensure welding密封性.
Automotive component cleaning:
Used to clean oil stains and impurities from the surfaces of engine blocks, crankshafts, connecting rods, and other components to improve assembly accuracy and performance. Ensures the normal operation of the transmission system and reduces wear and failure. Also used for brake discs, brake pads, etc., to remove oil stains, gum, and rust from the surface, improve braking performance, and ensure driving safety.
Automotive Repair and Restoration:
Localized Rust/Paint Removal: Precisely removes rust or damaged paint layers from specific areas of the vehicle body. Cleans oil stains, carbon deposits, rust, and old coatings from repair areas such as engine blocks, cylinder heads, and transmission housings, maximizing the retention of the original metal substrate. Laser cleaning systems equipped with machine vision technology can automatically identify rusted areas and plan optimal scanning paths, processing a 1-square-meter rusted surface in just 8 minutes.
Automotive Motors: Flat Copper Wire Laser Paint Removal:
Effectively and damage-free removal of paint layers, film coatings, PEEK layers, etc., from the surface of flat copper wires, with a removal time of less than 0.6 seconds per pass.
Automotive Electronics: IGBT Copper Busbar Laser Cleaning:
Laser cleaning of semi-finished products after welding ensures the surface cleanliness of IGBT chips meets bonding and wire bonding requirements.
Automotive tires: Laser cleaning of tire molds, tire inner walls, and wheel hubs Laser droplet technology expands laser processing applications in the tire industry
Laser cleaning equipment can not only remove rust, paint, oxide layers, and oil stains from various automotive components (such as wheels, brake pads, hoods, and engines), but also offers stable long-term operational costs, low maintenance rates, and no additional consumables. It can also help businesses save on labor costs and, more importantly, enable convenient automation.
