Cleaning methods for stamped parts mainly fall into two categories: physical cleaning and chemical cleaning. Ultrasonic cleaning is currently the most widely used and most effective mainstream method. This method efficiently removes contaminants such as oil, cutting fluid, and polishing wax from metal surfaces, and is particularly suitable for complex-structured, high-precision metal stamped parts.
Ultrasonic Cleaning (Mainstream High-Efficiency Method)
This is currently the most common cleaning technology for stamped parts in industry. It utilizes the "cavitation effect" generated by ultrasonic waves in a liquid to impact the workpiece surface, thoroughly removing dirt.
Workflow: Typically consists of multiple stainless steel tanks, including an immersion tank, an ultrasonic tank, a rinsing tank, and a drying tank. Automatic transfer is achieved via a robotic arm, enabling fully automated cleaning.
Applicable Objects: Stamped parts with high cleanliness requirements, such as stainless steel parts, precision hardware parts, automotive parts, and electronic components.
Key Operating Points: Temperature should ideally be controlled between 50–80℃. Too low a temperature will affect the cleaning effect, while too high a temperature may damage the workpiece or waste energy. Cleaning time is generally set to 3–10 minutes, adjusted according to the degree of oil contamination. It is recommended to use a dedicated water-based cleaning agent, diluted at a ratio of 1:10–20, which is environmentally friendly and does not corrode materials. The frequency is typically selected between 20–80kHz, and the power density should be maintained between 0.4–0.8W/cm² to ensure sufficient cavitation.
