New Article: MMM Ultrasonic Metallurgy (4MB pdf) from Aluminium International Today, the journal of aluminium production and processing - May/June 2014. www.aluminiumtoday.com.

The quality and competitiveness of casting strongly depends on the quality of molten alloy and the technology used to produce it. With regards to quality, the casting of aluminium alloys is not easy, since alloys are prone to dendritic and heterogeneous structures, as well as the absorbtion of hydrogen during melting, which requires a specific melt processing operation in order to reduce and control the level of porosity in a microstructure after solidification. By H. Puga, M. Prokic, N. van Dongen.

Ultrasonic systems for the most demanding applications: "MMM Technology" (Multifrequency, Multimode, Modulated Sonic & Ultrasonic Vibrations) gives the best possible results in ultrasonic cleaning and sonochemistry systems as well as making many new applications possible (***MORE***). For the first time any complex mechanical system up to a mass of several tonnes, consisting of arbitrary resonating elements, can be driven efficiently (Learn more about MMM Power Supplies)

 

Featured Application: Metal casting with Ultrasonic Degassing and Grain-refinement

Gallery of ultrasonic metallurgy

This photo - video gallery showcases a variety of ultrasonic metallurgy tools and applications.


Brief video showing the rotion of fluids by ultrasonic vibration. Molten aluminum can also be rotated by ultrasonics in addition to degassing homogenization crystallization grain refining.

Please see also this video of fluid rotation by ultrasonics - another effect in metal processing in addition to degassing, homogenization, crystallization, grain refining. Here water and coffee particles are used to demonstrate the effect in the lab, but in reality liquid metal also rotates during processing.

The Mastersonic Tube Reactor - used to apply ultrasonics to liquids for through-flow sonochemistry applications

Our tube reactors, also based on MMM Technology, are ideal for all through-flow sonochemistry applications providing high intensity, uniform sonication under your complete control. Various sizes available.

A glass flask becomes a sonochemical reactor simply by the addition of the MPI clamp-on ultrasonic system

Our revolutionary clamp-on ultrasonic systems drive your existing pipes, reactors or pressure vessels, even glass tubes and vessels - with the versatility of MMM ultrasonics.

MMM Generator from MP Interconsulting - Multifrequency Multimode Modulated Sonic  Ultrasonic power supply

Ultrasonic systems for the most demanding applications: "MMM Technology" (Multifrequency, Multimode, Modulated Sonic & Ultrasonic Vibrations). Details pages for ultrasonic generators: OF series, OW series, IX series, controllers. MMM ultrasonics manuals on pdf.

Ultrasonic atomization with a twist - here we are atomizing molten metal!

An unusual application for ultrasonics - atomization of molten metal alloy. The sonotrode uses a special tip (which is different for atomizing different metals) and water cooling. More information.

Foil perforation testing shows the ultrasonic power delivered by MMM systems and unmatched uniformity throughout a large volume of water.

Foil immersed for only a few seconds in a benchtop ultrasonic reactor powered by MMM technology. The extent and uniformity of the perforation cannot be matched by any conventional ultrasonic system. The details page includes a small animation and the complete video clip is available for download on our download site.

A range of top quality push-pull ultrasonic transducers and modular generators for ultrasonic cleaning and sonochemistry applications

For high-energy ultrasonic cleaning and sonoreactors, if MMM technology is not required, we also offer this range of top-quality "Push-Pull" transducers (tube resonators), driven by modular generators to suit all power requirements.

We have developed equipment for major manufacturing companies in Switzerland and around the world. Here are some examples:

A SERIES OF EXTRAORDINARY AND UNIQUE BOOKS RECOMMENDED BY MPI

Coupled Tensors of Piezoelectric Materials State

Dr. Ljubisa Peric, Author

426 pages, English language version copyright ©2004 MPI. All international distribution rights reserved.

Purchase mathematical modelling of piezoelectric materials book

Some researchers spend a lifetime working towards the understanding of a specific complex problem and, as the culmination of their career, write a technical work offering such a profound and multilevel insight that it could not have been produced in any other way. Our contemporary lifestyle imposes enormous barriers against creating such life-career books, yet this is one. This extraordinary book provides incomparable understanding of piezoelectric materials and their behavior in electro-acoustic transducers.

Dr. Peric's book is available in English exclusively from MPI. To order the book, please use our online store, or read more here.
