Against the rapid growth of the new energy vehicle industry, the E&E system imposes stringent cleanliness requirements on components. Tiny oil contamination, metal debris and micron particles may lead to poor welding, sealing failure and even potential battery safety hazards. Sinobakr vacuum ultrasonic cleaning solution for NEV components is specially developed for precision cleaning of E&E parts such as battery housings, water cooling plates, busbars and reducer housings. It consistently meets OEM cleanliness standards including ISO16232 and VDA19, serving as an optimal high-cleanliness cleaning solution for NEV production lines.

The solution adopts a combined vacuum-ultrasonic cleaning process. Vacuum degassing removes air blockages inside blind holes, deep cavities and intersecting oil passages. Together with ultrasonic cavitation, the hydrocarbon solvent penetrates interlayer gaps and microchannels to efficiently strip cutting oil, stamping oil, aluminum powder, copper chips and various micron impurities. It addresses the pain points of traditional cleaning methods such as insufficient cleaning in deep cavities and dead zones. The whole process is water-free, supported by low-temperature vacuum drying. Aluminum alloy, copper busbars and other oxidation-prone workpieces are free from whitening, watermarks, discoloration and corrosion after cleaning. It effectively improves the yield of subsequent welding, sealing and bonding processes and reduces the risk of battery pack short circuits.

Chlorine-free neutral hydrocarbon solvent is applied with excellent material compatibility. It causes no corrosion or hydrogen embrittlement and is suitable for common NEV component materials including aluminum alloy, copper, cast iron, stainless steel and powder metallurgy, without damaging precision mating surfaces. Cleanliness is stable and controllable. It steadily achieves the micron-level cleanliness required by OEMs in mass production, with controllable residual oil and particle indicators and favorable batch consistency to satisfy high NAS grade requirements.

For safety, the equipment features full Ex IIB T4 explosion-proof configuration, including explosion-proof electric control, explosion-proof motor and online flammable gas monitoring. It triggers automatic alarm and shutdown once the concentration exceeds the limit. The fully sealed cavity restrains solvent volatilization and keeps the workshop free of pungent odors for smooth fire inspection. It delivers outstanding environmental and economic benefits. The built-in vacuum distillation regeneration system achieves a solvent recovery rate of over 99% for cyclic reuse, with minimal waste liquid and zero wastewater discharge, eliminating the investment and maintenance cost of water treatment facilities. Equipped with a VOC treatment system, it meets emission standards. ODS-free, it complies with carbon neutrality targets and REACH regulations.

With a modular structure and PLC automatic control, the equipment supports flexible adjustment of process parameters. It can work as a standalone unit or be inline integrated into automated production lines. It supports rapid changeover of multiple workpieces for pilot small and medium-batch production as well as high-volume continuous production. Featuring easy operation and convenient maintenance, it helps NEV component manufacturers stabilize cleanliness control, cut costs and improve efficiency.
