2. Product Overview & Application Scenarios
2.1 Equipment Brief
Sinobakr single tank ultrasonic cleaning machine is an integrated single-chamber industrial cleaning equipment with only one main cleaning tank. It features a compact structure and small footprint, balancing mass cleaning and flexible operation. Three series are available: small desktop laboratory models, medium standard industrial models and heavy-duty customized large models, covering models BK-2400, BK-3600, BK-7200, etc.
2.2 Workpieces for Cleaning
Automotive industry: Bearings, engine parts, oil pans, valves, stamped and die-cast components to remove cutting fluid, polishing wax and oxide scale
Precision manufacturing: Hardware moulds, gears, hydraulic parts, PCB circuit boards, chip housings
Medical & optical industries: Surgical instruments, optical lenses, jewellery and watch parts
General machining: Mechanical spare parts, screws, stamping hardware, tooling fixtures
2.3 Removable Contaminants
Motor oil, cutting fluid, polishing paste, dust, metal debris, rust, fingerprints, release agents and thin oxide layers.
3. Core Structure & Materials
3.1 Cleaning Tank
The tank is integrally stamped from thickened SUS304 / SUS316 stainless steel with seamless construction, acid & alkali resistance and anti-corrosion against special solvents. SUS316L tanks are compatible with hydrocarbon and modified alcohol cleaning agents, featuring leak-proof and rust-resistant performance for long-term service.
3.2 Core Ultrasonic System (Core Advantages of Sinobakr)
Self-developed IGBT full-bridge ultrasonic generator with dynamic impedance matching technology for stable and non-decaying power output
Imported ceramic piezoelectric transducers bonded with high-temperature adhesive, resistant to detachment under long-term vibration. Transducers are arranged at tank bottom and side walls to form uniform sound fields, eliminating blind cleaning zones in deep holes and threaded holes
Optional frequencies: 28kHz, 40kHz, for heavy-duty rough cleaning or ultra-precise small-part cleaning as required
3.3 Intelligent Electric Control System
Two configurations for selection:
Standard version: Digital display panel with one-button setting of cleaning time and constant heating temperature (adjustable from 0℃ to 80℃)
High-end industrial version: Siemens PLC touch screen, storing multiple sets of custom cleaning processes. Built-in over-temperature, overload and short-circuit protection, compatible with workshop MES production line systems
3.4 Optional Auxiliary Modules
Circulating filtration system (filters oil and impurities to extend cleaning agent service life), automatic flip cover, movable casters, high-pressure spraying, hot air drying and defoaming systems.
4. Key Product Advantages
Efficient cleaning without workpiece damagePhysical cavitation cleaning penetrates micropores, threads and gaps for 360° all-round cleaning with no dead zones. No mechanical abrasion prevents scratches on plating and precision mating surfaces.
Stable non-stop productionIndustrial-grade heat dissipation supports 24-hour continuous operation, delivering stable output for intermittent workshop production lines.
Energy-saving & low operation costCleaning can be performed with water plus a small amount of water-based detergent to cut consumable costs. Low-noise operation without dust pollution; solvent recovery modules achieve over 99% solvent recycling rate for relevant models.
User-friendly operation & easy maintenanceVisual temperature and timing controls enable quick operation by novice workers. Detachable filter screens and independent generators simplify inspection and part replacement. Equipped with mobile casters for flexible station relocation.
Strong non-standard customization capacityCustomizable tank dimensions, ultrasonic power, and integrated single-tank washing & drying all-in-one machines to meet exclusive cleaning demands of special workpieces.
Long service life & reliable durabilityThickened rack with anti-corrosion spray coating. Core components including transducers and electric controllers enjoy a 1-year warranty, with dedicated maintenance for wear parts. Multiple service offices nationwide provide rapid after-sales support.
5. Working Principle
After power-on, the generator converts high-frequency electric energy to drive transducers at the tank bottom to produce high-frequency mechanical vibration. Billions of tiny cavitation bubbles form inside the liquid; instantaneous bubble implosion generates impact force to strip oil and impurities from workpiece surfaces. Constant temperature heating accelerates grease dissolution, while the circulating filter continuously purifies cleaning liquid to achieve rapid thorough cleaning.
6. Standard Operating Procedures
Fill the tank with water or special cleaning agent to the standard liquid level
Place workpieces into the cleaning basket and fully submerge them in liquid
Set target temperature and cleaning duration via touch screen or control panel
Start ultrasonic cleaning; the machine automatically stops when the countdown ends
Take out workpieces, rinse with clean water and air-dry
