Customized Single-Tank Ultrasonic Cleaning Machine for Metal Rust Removal in Hardware

An ultrasonic cleaning machine for hardware derusting is a device that utilizes high-frequency sound waves to generate cavitation effects in a liquid, aiming to remove dirt and impurities from the surface of objects. This cleaning method is particularly effective for industrial derusting because it can penetrate into the tiny gaps and holes of parts, removing rust and dirt that are difficult to reach by traditional methods.

The working principle of the ultrasonic cleaning machine is based on the following key factors:

Cavitation effect: When ultrasonic waves propagate through a liquid, they generate a series of tiny bubbles. These bubbles form during the peaks of the ultrasonic waves and rapidly shrink and collapse during the troughs. This process is called the "cavitation effect." The collapse of cavitation bubbles produces shockwaves, which impact and vibrate dirt particles, thereby stripping the dirt from the object's surface.

Mechanical vibration effect: In addition to generating cavitation, ultrasonic waves also cause vibrations in liquid molecules. This vibration exerts mechanical force on dirt particles, helping to dislodge them from the object's surface.

Micro-jet effect of the liquid: When ultrasonic waves propagate through a liquid, they generate micro-jets—tiny jets of liquid. These micro-jets can penetrate small cracks and holes on the object's surface, directly acting on the dirt and enhancing the cleaning effect.

Application Scope

Automotive manufacturing: Used for surface treatment of automotive parts, including derusting and cleaning of engine components, body structural parts, etc.

Aerospace: Surface treatment of aerospace devices and components to improve their surface quality and performance.

Electronics manufacturing: Used for cleaning and derusting electronic components to ensure surface cleanliness and reliability.

Metal processing: Includes derusting, degreasing, and cleaning of metal materials such as steel, copper-aluminum alloys, etc., to improve processing quality and technological performance.

Ultrasonic Frequency for Cleaning Objects

For powder metallurgy parts such as magnetic cores, magnetic rings, and parts with grinding magnetic powder, choose a frequency of 20-25 kHz.

For rough-processed metal parts, such as large components like car hubs and cylinder assemblies, choose a frequency of 25-28 kHz.

For watch parts and precision stamped parts, choose a frequency of 40 kHz.

For optical glass and low-end liquid crystal devices, choose a frequency of 68-120 kHz.

For cleaning semiconductor silicon wafers and liquid crystal glass substrates to remove 1-3 μm dirt particles, choose a megahertz-level frequency of 0.8-1.0 MHz.
