Ultrasonic Cleaners for Pre PVD/DLC Parts

In the coating process, ultrasonic cleaning machines are widely used in the pre-treatment stage of various precision components and serve as a critical process to ensure coating quality.

The components to be cleaned cover a wide range of categories, including cemented carbide tools (e.g., drill bits, taps, broaches), molds (injection molds, stamping molds), consumer electronic components (mobile phone/ computer logos, SIM card components), optical elements (lenses, prisms), precision metal parts (watch and clock components, eyeglass frames), electronic devices (semiconductor silicon wafers) and glass products (coated glass, ITO conductive glass).

Various impurities such as dust, fingerprints, grease, polishing residue, metal shavings and organic contaminants tend to adhere to the surface of such components. By generating a cavitation effect through high-frequency vibration, ultrasonic cleaning machines can deeply clean the complex structural areas of components, efficiently remove various stains bonded to the surface via physical adsorption and chemical combination, and completely solve the pain point of blind spots that are inaccessible with traditional cleaning methods.

After cleaning with this process, the adhesion between the coating layer and the substrate is greatly enhanced, and cross contamination in subsequent processes is effectively avoided, which safeguards the service performance and durability of components from the source.
