Core Challenges in Die Casting Parts Cleaning
After demolding, die casting parts (especially aluminum alloys) typically retain:
Release agents (silicone-based or water-based)
Oil and cutting chips
Fine metal particles
Oxide layers
These contaminants severely affect subsequent surface treatments such as plating, coating, and anodizing.
Ultrasonic cleaning uses high-frequency sound waves to create micro-bubbles in the liquid. The micro-shock waves generated when bubbles collapse effectively remove oil and particles from complex structures.
| Parameter | Recommended Setting |
|---|---|
| Frequency | 40 kHz (for complex structural parts) |
| Temperature | Strictly controlled to avoid overheating |
| Cleaning Solution | Neutral or weakly alkaline water-based cleaner |
| Time | 5-10 minutes |
Precautions:
For aluminum alloys, use neutral cleaning solutions to avoid corrosion or pitting from strong acids/bases
Conduct small-area testing before full-scale cleaning
For burrs and oil in complex areas such as inner holes, cross holes, and blind holes of die casting parts, high-pressure water jet is an efficient solution.
Equipment Features:
Adjustable system pressure (50-80 MPa)
Customizable water jet angles (45° bevel, 90° bilateral, etc.)
Can penetrate cross holes, threaded holes, and deep holes for deburring and cleaning
Simultaneously removes oil, particles, and chips
Water can be recycled and filtered for environmental protection and energy saving
