| Aqueous Ultrasonic Cleaning | Aqueous cleaning agent emulsification + ultrasonic cleaning | General automotive parts, high environmental requirements | Low cost, high safety, eco-friendly |
| Vacuum Solvent Cleaning | Vacuum degassing + solvent cleaning + vapor drying | High cleanliness requirement parts | 360° no dead angles, short drying time, distillable regeneration |
| Spray Cleaning | High-pressure spray + cleaning agent flushing | High-volume, regular-shaped parts | High efficiency, suitable for automated production lines |
II. Typical Equipment Configuration Solutions
1. Fully Automatic Vacuum Hydrocarbon Cleaning Machine (High-end Precision Parts)
Standard Configuration: Vacuum degassing ultrasonic cleaning tank → Powerful vacuum ultrasonic cleaning → Vapor washing + vacuum drying
Core Functions:
- Vacuum degassing technology: Removes air from cleaning liquid to enhance ultrasonic cavitation effect
- Vacuum flash drying: Completes drying within minutes, efficiency improved by 8x or more
- Solvent distillation regeneration: Recyclable for over 200 cycles, saving over 100,000 yuan annually
- Explosion-proof safety design: Isolates oxygen in vacuum state to eliminate combustion risk
2. Multi-tank Ultrasonic Cleaning Line (Batch Production)
Typical Process: Ultrasonic rough cleaning → Ultrasonic fine cleaning → Rinsing → Drying
Configuration Example:
- Ultrasonic frequency: 28kHz (general) / 40kHz (precision)
- Power density: 3-5W/cm²
- Temperature control: 20-80℃ adjustable
- Filtration system: Removes impurities, extends cleaning liquid lifespan
3. Step-through/Rotary Basket Cleaning Machine (Complex-shaped Parts)
- 360° rotating cleaning, no dead angle coverage
- Particularly suitable for stamped housings, battery cases with grooves and blind holes
- Can be configured with anti-rust function, extending corrosion protection by 3-6 months
III. Cleaning Agent Selection Recommendations
| Cleaning Agent Type | Characteristics | Suitable Contaminants | Precautions |
|---|---|---|---|
| Hydrocarbon Cleaning Agent | Strong dissolving power, volatile and residue-free, low-toxicity | Mineral oil, machining oil, anti-rust oil | Requires explosion-proof equipment, flash point ~50℃ |
| Modified Alcohol | Stronger dissolving power, fast drying | Heavy oil, wax, gum | Requires sealed vacuum system |
| Aqueous Cleaning Agent (weakly alkaline pH 8.0-10.5) | Eco-friendly and safe, low cost | General cutting fluid, light oil contamination | Requires rinsing, pay attention to material compatibility |
| Semi-aqueous Cleaning Agent | Performance in between | Mixed oil contamination | Subsequent processing more complex |
Selection Principle: According to the "like dissolves like" principle, hydrocarbon cleaning agents have optimal compatibility with machining oils (both being non-polar petroleum fractions), delivering better cleaning results than halogenated hydrocarbons and aqueous cleaning agents.
IV. Key Technology Trends (2025-2026)
- Composite Cleaning Technology: Combination of ultrasonic + vacuum + spray, more effective for blind holes and deep holes
- Low-VOC Eco-friendly Solutions: Complying with increasingly strict environmental regulations
- Intelligent Control: PLC automatic control, visual positioning, robotic loading/unloading, supporting 24-hour continuous operation
- Solvent Recovery Systems: Vacuum distillation regeneration, solvent loss rate controlled within 5%
- Multi-station Flexible Production Lines: Adapting to multi-variety, small-batch production needs
V. Selection Recommendations
| Application Scenario | Recommended Solution | Key Considerations |
