Laser Cleaning Before and After Automotive Welding:
Removes oil, rust, oxide coatings (such as zinc plating), mold release agents, and other contaminants from welding areas (such as body panels, chassis components, battery trays, etc.). Significantly improves weld quality and strength, reduces welding defects (such as porosity and incomplete welds), and increases weld yield. Pre-welding cleaning is crucial; laser cleaning removes impurities such as oil, dust, and oxide layers from welding areas, improving weld quality, reducing defects like porosity and slag inclusions, and ensuring weld strength and reliability. BMW Group application examples show that this technology can improve cylinder block cleaning efficiency by 65%, reducing the welding defect rate to below 0.02% by precisely removing oxide layers as thin as 0.1-0.3mm.
Automotive Mold Cleaning and Maintenance:
Removes mold release agent residue, carbon deposits, polymer residue, oxides, etc., from the surfaces of stamping dies, injection molds, and casting molds. Restores mold surface smoothness, ensures product quality (such as the surface smoothness of stamped body parts), extends mold life, and reduces downtime for maintenance.
Power Battery Manufacturing:
Electrode Cleaning: Removes oil and oxides from the surface of the metal foils (copper and aluminum foils) on the positive and negative electrodes of the lithium battery before coating, improving the adhesion of the coating slurry.
Pre-Welding Cleaning: Cleans oxides and residual insulation from welding areas such as battery tabs, connectors, and busbars, ensuring welding quality and reducing contact resistance.
Pre-Sealing Pin Welding Cleaning:
Cleans the welding area of the sealing pins on the battery cover to ensure a tight seal.
Automotive Parts Cleaning: Used to clean oil and impurities from the surfaces of engine blocks, crankshafts, connecting rods, and other components, improving assembly precision and performance. Ensures the normal operation of the transmission system, reducing wear and malfunctions. Also used for brake discs and pads, removing surface oil, gum, and rust, improving braking performance and ensuring driving safety.
Automotive Repair and Refurbishment:
Local Rust/Paint Removal: Precisely removes rust or damaged paint from specific areas of the vehicle body. Cleans oil, carbon deposits, rust, and old coatings from repair areas such as engine blocks, cylinder heads, and transmission housings, preserving the original metal substrate to the greatest extent possible. Laser cleaning is equipped with a machine vision system that automatically identifies rusted areas and plans the optimal scanning path, processing 1 square meter of rusted surface in just 8 minutes.
Automotive Motors: Laser Stripping of Flat Copper Wires: Effectively and non-destructively strips the enamel, film coating, and PEEK layer from the surface of flat copper wires, with a stripping time of less than 0.6 seconds per strip.
Automotive Electronic Control Systems: Laser Cleaning of IGBT Copper Busbars: Laser cleaning of the semi-finished products after welding ensures that the surface cleanliness of the IGBT chips meets the requirements for wire bonding.
Laser cleaning equipment can not only remove rust, paint, oxide layers, and oil stains from various automotive parts (wheel hubs, brake pads, hoods, engines, etc.), but it also offers long-term cost-effectiveness, low operating costs, low maintenance rates, and no consumables. It can also save businesses labor costs and, more importantly, easily automate the process.
