Laser processing is widely applied in the manufacturing of new energy vehicles. Thanks to its high flexibility, superior processing precision, fast speed and excellent processing quality, it delivers outstanding cost performance in numerous manufacturing procedures. DOYA’s products have extensive applications in this sector, which we will introduce today.

Laser Marking

Laser marking can be performed on nearly all materials and various irregular surfaces with great flexibility, catering to diverse and complex requirements. For automotive parts, electronic products and other items that demand high quality and durability, laser marking is an ideal option with high quality and long-lasting marks.

Hairpin Enamel Stripping

Common insulating materials for hairpins include organic composite materials such as polyamide (PA), polyether (PE) and polyimide (PI). These materials feature strong absorption of longer wavelengths within the far-infrared spectrum. Therefore, we regard CO₂ lasers as the optimal solution for removing residues on flat copper wire surfaces. Moreover, CO₂ lasers can effectively strip the insulation layer without damaging the base material. Boasting excellent cost performance, they are an ideal choice for flat wire stripping and have been widely adopted in current production.

Interior Trimming & Processing

Laser processing offers outstanding advantages for cutting and other operations on interior fabrics. It delivers clean cuts without burrs and causes no damage to materials. Both its processing accuracy and repeatability are superior to traditional processes. In addition, laser processing can perform micro-perforation, scribing and other operations on automotive trims made of leather, fabrics and synthetic materials.

Structuring Processing of Metal Foil

Laser ablation and other treatments are used to form 3D microstructures on metal foil, enabling better adhesion of active materials and thus extending battery service life.

Active Material Processing

Diffusion channels are created inside electrodes to optimize their electrochemical performance and reduce loss of active materials. DOYA’s galvanometers and motors can produce fast, efficient hole patterns with micron-level precision.

Electrode Slitting

Laser slitting is gradually replacing mechanical slitting in electrode cutting processes. Laser electrode slitting delivers high precision with simple and efficient operation, and patterns and geometries can be modified at any time.

Laser Contact Processing

Laser contact processing stacks and welds multi-layer films together to form electrical components. DOYA’s products support a wide range of wavelength options and are compatible with many types of laser sources. Meanwhile, SMC/SMD oscillation technology ensures high-integrity welds.

Laser Cleaning

Laser cleaning removes dust, oxides and other coatings that may compromise bonding quality, helping improve battery surface quality and electrical conductivity. Featuring eco-friendliness, high efficiency and minimal damage to foils, laser cleaning has become the preferred method for electrode cleaning.

Laser Seam Welding / PACK Welding

There are extensive welding requirements for individual cells and battery modules, requiring high-quality, hermetic welding on copper, aluminum and alloy materials. Batteries are assembled in the final manufacturing step by laser welding cells onto busbars. DOYA’s 3-axis scanning galvanometers enable flexible welding for different materials and positions.
