Sinobakr vacuum ultrasonic cleaner is high-end precision industrial cleaning equipment independently developed by Jinan Sinobakr Ultrasonic Technology. Since 2000, the brand has been engaged in industrial cleaning for more than 20 years. Adopting the combined technology of vacuum degassing and ultrasonic cavitation, it solves the difficulties of traditional ultrasonic cleaning in workpieces with deep holes, blind holes and intersecting cavities. It serves as one of the major domestic equipment for import substitution in high-end precision manufacturing.

Its core working principle lies in the synergy of vacuum degassing and multi-frequency ultrasonic waves. Before cleaning, the chamber is evacuated to remove air from solvent and micropores of workpieces, eliminating air blockage and reducing attenuation of ultrasonic energy to strengthen cavitation effect. Ultrasonic waves generate numerous tiny cavitation bubbles. When these bubbles burst inside gaps and blind holes of workpieces, they physically strip cutting oil, metal powder, polishing wax, grease and other contaminants without damaging workpiece coatings and precision threads. The whole process generally consists of five procedures: vacuum spray pre-cleaning, variable-frequency ultrasonic fine cleaning, vacuum rinsing, vapor bath cleaning and vacuum low-temperature drying. Some models are equipped with a solvent distillation regeneration system to recycle cleaning solvent, greatly cutting consumable costs.

The chamber is made of thickened 316 stainless steel with good corrosion resistance, compatible with environmentally friendly solvents such as hydrocarbon and modified alcohol. The electrical system adopts explosion-proof design, fitted with flammable gas monitoring, leakage alarm and automatic protection functions. The sealed chamber effectively restrains solvent volatilization with no odor in workshops, complying with fire protection and environmental standards. Controlled by PLC and touch screen, it allows presetting of temperature, vacuum degree, ultrasonic power and cleaning cycles. It supports one-click automatic operation and can connect with manipulators for automatic loading and unloading to integrate into automatic production lines. Available in single-chamber integrated and multi-station modular structures, it can be non-standard customized according to workpiece dimensions and cleanliness requirements.

Compared with ordinary ultrasonic cleaners, the biggest advantage of Sinobakr vacuum ultrasonic cleaning is no watermarks and no oxidation after cleaning. Low-temperature drying by vacuum bumping prevents solvent residue in deep holes and narrow slits of workpieces. Aluminum and powder metallurgy parts will hardly suffer from whitening oxidation. The cleaning cleanliness can reach NAS 7~8 grade, meeting the micron-level cleaning standards of automotive OEMs and aerospace industries. The solvent distillation circulation design minimizes waste liquid discharge, and the waste heat recovery structure further reduces energy consumption for higher environmental friendliness.

This equipment is widely used for automotive parts, new energy motor housings, hydraulic valve blocks, precision bearings, aerospace components, medical devices, semiconductor hardware and other industries. It is suitable for batch cleaning of precision workpieces with complex cavities and micro holes. The product holds multiple international certifications including ISO9001, CE and UL. Its service network covers the whole country and products are exported overseas. It is preferred equipment for high-quality, stable and eco-friendly cleaning in precision manufacturing.
