Ultrasonic Cleaning

In the world of precision manufacturing, cleanliness is far more than just an appearance indicator; it's a critical performance parameter concerning a product's intrinsic quality and long-term reliability. After stamping, stamping oil, metal shavings, environmental dust, and even fingerprint grease inevitably accumulate on the surfaces and in the microscopic gaps of parts. These seemingly insignificant contaminants, if not thoroughly removed, will become fatal "killers" in subsequent high-temperature welding and precision assembly. They hinder direct fusion between metals, leading to weak welds and porosity; they form spacers on precision mating surfaces, affecting assembly accuracy and heat conduction; and they can even cause electrochemical corrosion during long-term use, disintegrating the product from within.

Therefore, before entering the core welding and assembly stages, we must utilize ultrasonic cleaning technology to achieve "microscopic" cleanliness for all parts. We employ an advanced multi-tank ultrasonic cleaning system. Its working principle utilizes a high-frequency electrical energy transducer to generate extremely high-frequency acoustic vibrations in a specialized chemical cleaning solution. This vibration creates countless micron-sized vacuum bubbles in the liquid, invisible to the naked eye and appearing and disappearing instantaneously—a phenomenon known as "cavitation." When these bubbles burst near the surface of the part, they instantly generate localized high pressure exceeding one thousand atmospheres and intense micro-jet shock waves.

This powerful force can penetrate into the smallest crevices, blind holes, and the bottom of threads of any complex shape, thoroughly stripping, emulsifying, and dispersing various contaminants adhering to the workpiece surface. Its cleaning effect is unparalleled by traditional soaking and brushing processes, achieving comprehensive and thorough cleaning. This process ensures that every workpiece is in a perfectly clean state before entering the next critical stage. It fundamentally eliminates welding defects, poor assembly, and potential corrosion risks caused by surface contamination, and is an indispensable prerequisite for ensuring high welding quality, perfect assembly fit, and ultra-long service life. In short, ultrasonic cleaning is a thorough "detoxification" of the product at the microscopic level for its long-term health.
