I. Industry Cleaning Pain Points

1. Die-cast motor housings feature a complex structure with numerous inner cavities, cooling fins, mounting holes, threaded holes and water channel grooves. Gaps and dead corners easily trap contaminants.

2. Residues such as die-casting release agent, aluminum scraps, cutting oil, dust and oxide scale are hard to remove thoroughly by ordinary cleaning methods.

3. New energy motor assembly has extremely high requirements for cleanliness, watermark-free surface, corrosion resistance and zero residue, to prevent poor insulation, abnormal noise and sealing leakage.

4. Mass production requires high cycle efficiency and automatic line compatibility, balancing high-efficiency cleaning, fast drying and environmental compliance.
