Innovative Aspects
Development of a new ultrasonic electronics and a system feedback concept that allows real-time adaptation to continuously evolving acoustic conditions. Capability to ultrasonically drive any arbitrary shape or large mechanical system at high energy if needed- Ultrasonic driving of system harmonics and subharmonics gives a wideband multi-frequency effect that improves stimulation of the system. - Elimination of ultrasonic standing waves gives uniform treatment of material
Main Advantages
Improved metal homogenization and mixing of new alloys.- Improved crystallization and alloy characteristics in casting.- Friction reduction between a tool (e.g. casting, drawing, extruding, moulding) and the material being worked improves the material flow.- Improved Surface finish on extruded or drawn materials.- Reduce or eliminate material voids or cavities in casting or moulding applications.- Power Supply Generators are available in a standard range of 300 watts to 2,000 watts. Custom systems available to 120,000 watts.
Advantages and applications:
- grain refinement, with significantly improved and 3D uniformly distributed micro-crystallization.
- disintegration, elimination, wetting and dissolving of non-metallic and metallic inclusions, making smooth intermetallic transitional area.
- Alloys mixing with nano-particles, increasing density of the alloys, varying percentages of alloys ingredients.
- Improving chemical, mechanical and physical properties and corrosion resistance e.g. in Al-Li alloys and other aerospace alloys.
ALUPRO-MPI Ultrasonics Inc. has developed a new technology that applies high power ultrasonic energy to large, heavy irregular mass or un-tuned mechanical systems such as extruder, drawing die, mould tools, metal melt mixer, continuous casting, homogenizing, degassing, alloying, very fine and homogenous micro-crystallization, sintering, etc .
Conventional power ultrasonic systems comprising the power supply generator and piezo-electric transducers, as used in ultrasonic cleaning and welding applications, are limited in function and adaptability to new metal working applications. ..
A new revolutionairy ultrasonic generator technology has been developed to allow the use of conventional high amplitude transducers to drive large irregular shapes and un-tuned mechanical systems such as extruder heads, drawing die, injection mould tools, or a metal melt mixer.
This new technology has the unique capability to stimulate wide-band sonic and ultrasonic energy (ranging from infrasonic up to the MHz domain). The key to the technology is its use of a proprietary technique to analyze feedback signals and create custom driving wave forms to initiate and control ringing and relaxing, modulated, multimode mechanical oscillations in the harmonics and sub-harmonics of the attached mechanical system.
