I. Main Challenges in Die Casting Housing Cleaning
Die casting housings (such as engine housings, transmission housings, motor housings, etc.) face unique cleaning challenges during manufacturing :
- Complex Structures: Blind holes, threads, gaps, cross holes, internal cavities and other difficult-to-reach areas
- Multiple Contaminants: Release agent residues, cutting fluids, aluminum chips, oil, casting sand, oxides
- Material Characteristics: Aluminum alloy is relatively soft, prone to scratching, and thin-walled sections are susceptible to deformation
- High Cleanliness Requirements: Affects subsequent assembly precision, sealing performance, and service life
II. Core Cleaning Technologies
1. Ultrasonic Cleaning Technology (First choice for precision cleaning)
Working Principle: Utilizes "cavitation effect" generated by ultrasonic waves in the cleaning fluid, creating countless micro-bubbles that implode instantaneously, producing powerful impact forces that penetrate microscopic gaps to thoroughly remove contaminants
Technical Advantages:
- Cleaning efficiency improved by 3-5 times
- Achieves all-round, dead-angle-free cleaning
- Protects housing surface precision, avoiding mechanical damage
- Suitable for complex structural parts
Frequency Selection:
- 28kHz: Removing stubborn release agents, casting sand
- 40kHz: Standard cleaning, suitable for most die castings
