Ultrasonic cleaning systems for tool cleaning

Intermittent cleaning of die-casting, rubber or plastic injection molding tools is essential for the problem-free production of cast and injection-molded parts. Multi-stage tool cleaning using ultrasound completely replaces the very laborious and time-consuming cleaning of tools using manual methods.

Our systems are specially designed to meet customer requirements, enabling us to maximize the efficiency of the systems for our customers and minimize the costs and space required.

Our cleaning systems for tool cleaning are individually assembled as a 2-, 3- or 4-station system concept. The individual process stages can be freely assembled and combined as modules:

Ultrasonic bath module - cleaning tools using ultrasound

Different ultrasonic frequencies are used depending on the contamination and the material to be cleaned. A frequency of 18 to 21 kHz (magneto-strictive ultrasound) or piezo ultrasound (25 kHz) is commonly used for tool cleaning. The combination of ultrasound, the appropriate cleaning agent (powder or liquid, concentration 3-15% / rest water) and the temperature (usually 65-75 °C) produces the best reproducible cleaning results.

Flushing module (clear water)

After cleaning in the ultrasonic bath, the adhering cleaning medium is washed off in the rinsing bath. The rinsing effect is supported by air flooding (whirlpool effect), allowing the tool to be transferred to the next work step after a few seconds.

Passivation module (aqueous)

During passivation, the tool is placed in a water bath with 0.5 - 3 % aqueous corrosion protection. This protects it from corrosion for a longer period of time. Aqueous passivation is an alternative to preservation using dewatering fluid. dewatering fluid (KW/solvent).

Preservation module (dewatering)

During preservation, the cleaned or rinsed tool is immersed in so-called dewatering fluid is immersed. This wets the surface with a long-lasting long-lasting corrosion protection and at the same time displaces water that which has remained on the tool due to previous stages. This means that it dries quickly on its own. Preservation using dewatering fluid is an alternative to aqueous passivation.

Blow-off module

In the final step, the tools are manually blown off using compressed air in a closed module to remove any residual moisture from holes and threads. For smaller tools, this can also be done automatically in a circulating hot-air dryer.
