Its core principle is ultrasonic cavitation effect. The Buck machine adopts combined ultrasonic and spraying cleaning for thin-walled aluminum and copper stamping parts. Together with cleaning medium, circulating filtration and automatic processes, it removes stamping oil and fine metal debris from gaps without damaging workpieces.

1. Conversion of electric energy into high-frequency vibrationThe ultrasonic generator outputs high-frequency electrical signals, which are converted by transducers into mechanical vibrations of tens of thousands of hertz and transmitted into the cleaning liquid (water-based cleaning agent), forming an acoustic field with alternating dense and sparse waves.

2. Formation and collapse of cavitation bubbles (core mechanism)During the negative pressure phase of sound waves, the liquid is stretched and torn to generate numerous micron-sized tiny cavitation bubbles. In the positive pressure phase, the bubbles are rapidly compressed and implode instantly. Upon collapse, the bubbles release shock waves, high-speed microjets and instantaneous local high pressure. The effect reaches all gaps, blind holes and folded dead corners that the liquid can wet. It strips and disperses drawing oil and metal debris adsorbed on the surface and micro-textures of aluminum and copper stamping parts. This is non-contact physical cleaning. With properly adjusted frequency and power, it will not scratch or deform thin-walled workpieces.

3. Auxiliary flushing by combined sprayingAfter dirt is stripped by ultrasound, multi-angle high-pressure spraying washes away suspended oil contamination, aluminum and copper chips to prevent re-adhesion of impurities to the workpiece surface. Combined with water-based cleaning agents that emulsify oil stains, the degreasing performance is further improved.

4. Circulating filtration, rinsing and dryingStripped contaminants flow with the cleaning liquid and are continuously trapped through oil-water separation and precision filters. The workpieces then go through multi-stage pure water rinsing, air knife water removal and hot air drying to eliminate residual cleaning agent and water stains, ensuring stable cleanliness that meets ISO 16232 cleanliness requirements for automotive components.

5. Adjustable multi-frequency design for thin-walled partsFor soft thin-walled aluminum and copper stamping parts such as battery housings and busbars for new energy vehicles, multi-frequency / sweep-frequency ultrasound is adopted. High frequency delivers gentle energy for fine particle removal, while low frequency generates stronger cavitation impact for heavy oil stains. Controllable cavitation strength balances cleaning performance and workpiece protection, avoiding corrosion and deformation of thin-walled parts.

Concise one-sentence version: The generator drives transducers to produce cavitation bubbles in the cleaning liquid. The bursting bubbles generate microjets and shock waves to strip oil and debris from gaps of stamping parts. Assisted by spraying flushing, filtration, rinsing and drying, the machine achieves non-damaging precision cleaning for thin-walled aluminum and copper parts.
