Ultrasonic treatment for improved casting quality – High-quality metal components for demanding applications

The casting process is crucial for the quality of metal components and significantly influences their durability and resilience. With increasing demands in mechanical engineering, the automotive industry, and aerospace, the need for advanced manufacturing technologies is growing.

Aluminum in particular plays a key role: its combination of excellent mechanical properties and low weight makes it one of the most important lightweight materials.

To optimize aluminum components for high-stress applications, we use an innovative ultrasonic treatment. This technology alters the metal's microstructure and significantly improves key mechanical properties.

How the ultrasound system works

The ultrasound system consists of four main components:

• Generator – Generates alternating current and transmits it to the transducer
• Transducer – Converts electrical vibrations into mechanical vibrations
• Booster (optional) – Regulates the amplitude of the oscillations
• Sonotrode – Transmits mechanical vibrations into the melt and creates massive pressure fluctuations

These pressure fluctuations change the microstructure from dendritic to globular, which significantly improves the mechanical properties of the material.

Advantages of ultrasonic treatment of aluminum

• Fine-grained structure – improved mechanical properties
• Increased strength and ductility – Higher load-bearing capacity of components
• Optimized casting quality – reduced porosity and more homogeneous microstructure
• Higher process control – improved reproducibility and material properties

Ultrasonic treatment of aluminum offers a groundbreaking solution for increasing the performance of this essential lightweight material – and thus meets the increasing demands of modern industries.
