Fully automatic ultrasonic cleaning process: manual loading by hand. — The first tank is an ultrasonic rough cleaning tank. — The second tank is an ultrasonic fine cleaning tank. — The third tank is for flushing with municipal water or pure water. — The fourth tank is for rinsing with municipal water or pure water. — The fifth tank is for rinsing with municipal water or pure water (or anti-rust immersion). — The sixth tank is a tunnel drying furnace equipment. — Manual cutting by hand. I. Features of the Fully automatic closed Ultrasonic Cleaning Instrument: * Excellent cleaning effect, high cleanliness and consistent cleanliness of all workpieces; It features a fast cleaning speed, replacing manual scrubbing and enhancing production efficiency. ※ No manual contact with the cleaning solution is required. It is environmentally friendly, scientific, safe and reliable. It can clean deep holes, narrow crevices and hidden areas of the workpiece thoroughly without causing any damage to the surface of the workpiece. ※ Save solvents, heat energy, working space and labor, etc. ※ It can be used for cleaning, dispersion, decomposition, emulsification, etc. Ii. Application of Fully Automatic Closed Ultrasonic Cleaning Instrument: (1) The ultrasonic cleaning machine for electronic and electrical appliances mainly cleans solder, oil stains, rosin, preservatives, paraffin, oxides, rust, etc. on switches, integrated circuits, electronic circuit boards, semiconductor components, silicon wafers, quartz crystals, magnetic heads, magnetic tapes, optical discs, optical fibers, relays, capacitors, alarms, memory devices, liquid crystal displays, and hard disk assemblies. (2). The ultrasonic cleaning machine for precious metals mainly cleans coatings, sprays, composites, abrasives, grinding oils, chips, chip oils, greases, hand stains, oxides, etc. of jewelry, ornaments, necklaces, jade, watches, glasses, as well as glass and ceramics. (3). Ultrasonic cleaning machines in the electroplating industry mainly clean metal structural parts such as vernier calipers, tooling fixtures, spectacle frames, surgical instruments, dental tools, hardware parts, watch parts, and fishing gear accessories for pre-plating cleaning of oil stains, rust removal, phosphating substances, etc. (4). Ultrasonic cleaning machines in the automotive industry mainly clean grease, preservatives, plastic residues, grinding abrasives, graphite, filters, etc. on engines, valves, ignition plugs, fuel pumps, fuel tanks, battery electrodes, piston rings, and machine control panel parts. (5). The aerospace ultrasonic cleaning instrument mainly cleans oxides, dust, chips, rust, carbon, scale, etc. on fuel filters, flow control equipment, gyroscopes, artificial satellites, and aviation hydraulic systems.
