A Ultrasonic cleaner for the workshop from BANDELIN ensures the necessary cleanliness of complex technical components and sensitive tools. While manual cleaning processes reach their physical limits with blind holes, narrow capillaries and branched internal geometries, acoustic cavitation automates this maintenance step. The process achieves deep pore cleaning even in inaccessible areas without affecting the surface morphology or the dimensional accuracy of the precision parts.
The technological lead of a Ultrasonic cleaner for the workshop is particularly evident in components with inaccessible interior spaces, as is the case with heat exchangers, complex valve blocks or oil coolers finds. Manual cleaning methods or pressure rinsing often fail here due to the surface tension and air pockets that act as a barrier. The cleaning fluid stands still in the fine channels and the dirt remains in the „dead zones“.
A Ultrasonic cleaner for the workshop utilises the acoustic conductivity of the workpiece to solve the problem. This vibration ensures that cavitation - i.e. the formation and implosion of microscopic vacuum bubbles - also takes place deep inside nested casting labyrinths. Where a brush cannot reach mechanically and a rinsing jet merely bounces off the air cushion, cavitation blasts resinification and residues directly from the wall. The liquid inside is „swirled“ microscopically by the ultrasound, which enables the dirt particles to be removed.
Reliable, non-destructive cleaning is the basic prerequisite for the reusability of components. Particularly when overhauling engine and machine components made of cast aluminium, non-ferrous metals or magnesium, the physical parameters determine whether a surface is cleaned or permanently damaged. A Ultrasonic cleaner for the workshop must dose the energy in such a way that layers are dissolved without attacking the basic structure.
The selected frequency is decisive for the mechanical load on the material. While 25 kHz systems generate large-volume cavitation bubbles with massive punctual impact force, BANDELIN Ultrasonic cleaner for the workshop primarily in the 40 kHz range. The physical advantage is decisive: at 40 kHz, significantly smaller and more numerous bubbles are created, the implosion force of which is precisely tuned to the removal of contaminants such as oil carbon, soot or resin deposits. This finer cavitation acts like a microscopic blasting process that removes even stubborn deposits without risking damage to sensitive structures or dimensional deviations in high-precision fits.
Thermal support breaks the adhesion of stubborn layers
Sound energy alone is not enough to overcome the molecular binding forces of industrial residues. Only the targeted coupling of temperature and surfactant chemistry enables successful cleaning. While the physical efficiency of cavitation reaches its maximum at around 50 °C, resinified lubricants often require significantly higher temperatures in practice. In a BANDELIN Ultrasonic cleaner for the workshop the temperature can be increased to 70 to 80 °C in order to safely exceed the dew point of specific contaminants. As soon as encrusted layers soften, the dirt loses its adhesion to the base material and can be completely removed by the ultrasonic waves. The coordinated TICKOPUR system chemistry then ensures that dissolved oils are either demulsified and removed from the component. They float to the surface and can be removed from the system using an oil separator, which significantly extends the service life of the cleaning bath. Alternatively, the oils are bound in the solution by emulsification. In both cases, they do not redeposit on the clean components.
An ultrasonic cleaner for the workshop must be able to withstand loads that far exceed the performance of household appliances. While inexpensive imported models often rely on thin-walled standard steels, BANDELIN manufactures the oscillating tanks from high-quality stainless steel (1.4404).
This alloy provides long-lasting protection against corrosion and continuous mechanical stress. The constant implosions of the cavitation bubbles act like microscopic hammer blows on the tank wall. While inferior steels become brittle under this stress or suffer intercrystalline corrosion from aggressive cleaning media, a SONOREX system remains diffusion-tight and dimensionally stable for years.
In industrial maintenance, cleaning baths are often loaded to their saturation limit. Cleaned particles, metal abrasion and sludge change the acoustic impedance of the liquid. These suspended particles act as additional nuclei on which cavitation is favoured, with the physical effect that part of the ultrasonic energy is discharged in the free bath on the dirt particles instead of acting directly on the surface of the workpiece.
With undersized cleaning systems, this leads to a massive drop in cleaning performance, as the remaining energy is no longer sufficient to break up stubborn dirt on the component. A Ultrasonic cleaner for the workshop from BANDELIN is designed to maintain a sufficiently high energy density on the workpiece even under difficult conditions thanks to its robust generators and the high efficiency of the piezoceramic transducer systems. The aim is to safely exceed the required cavitation threshold on the component despite increasing contamination and thus keep cleaning times constant.
Manual methods often only move dirt in blind holes or branched channels instead of removing it. Air cushions also prevent cleaning media from penetrating into the depths. A Ultrasonic cleaner for the workshop utilises the acoustic conductivity of the metal to generate cavitation on the inner wall. This „blasts off“ coking and resinification even where no brush can reach and no compressed air jet can work.
Resinated lubricants often have a dew point above 60 °C. A Ultrasonic cleaner for the workshop only unfolds its full effect when the heating exceeds this dew point. In combination with cavitation, the contamination is literally torn away from the component.
Fresh water contains dissolved gases that act like microscopic shock absorbers in the ultrasonic field. They dampen the force of the bubble implosion and reduce the cleaning performance by up to 30 %. Only degassing prepares the water for cavitation. This saves working time in the workshop, as the full cleaning power is available after the bath change.
Cast aluminium or magnesium is often used in maintenance. While low-frequency systems (25 kHz) generate excessively coarse bubbles with a high destructive force, a professional Ultrasonic cleaner for the workshop with 40 kHz. The finer bubbles guarantee that even stubborn soot is removed without damaging the sensitive surface morphology or precise bearing seats.
The service life in shift operation is ensured by the industrial design of the overall system: While the stainless steel oscillating tank resists mechanical cavitation erosion, specially manufactured piezo ceramics guarantee loss-free vibration transmission even at high bath temperatures. The generator electronics are dimensioned in such a way that they keep the cleaning power constant, even when fully loaded, without throttling the performance for thermal reasons. Integrated protection functions against dry running and overheating also safeguard the hardware against operating errors in everyday workshop use.
