The Institute of Technical Acoustics offers consumers a device for ultrasonic crimping of rubber products under a manufacturing agreement and is looking for partners to conclude a distribution services agreement.

Purpose: for thinning and protection fr om unraveling (delamination) of the cut of shoe gum after cutting it.
Scope: light industry.

The rubber band is placed between the lodgement (copy tool) and the ultrasonic emitter. The emitter is lowered onto the lodgement and when a certain pressing force is reached, ultrasonic vibrations are excited in it. Heat due to the dissipation of ultrasonic vibrations is localized wh ere the surface of the lodgment touches the rubber material, as a result of which it is deformed on the contact surface of the lodgment. After a predetermined period of time, ultrasonic vibrations are turned off and the cooling process begins, during which the polymer solidifies.

Benefits: 2-3 times higher productivity of the crimping process; reduction of energy costs by 8-10 times; exclusion of material sticking to the surface of the tool; uniform melting along the perimeter and thickness of the shoe gum; environmental safety of the process.

Implemented by: JLLC "Belwest" (Vitebsk).

The activities of the Institute correspond to the priority areas of scientific, technical and socio-economic development of the country and the Vitebsk region. The Institute conducts fundamental and applied research, as well as carries out scientific and technical developments within the framework of the state scientific research programs, the regional scientific and technical program, republican and international projects of the Belarusian Republican Foundation for Fundamental Research (BRFFR), individual projects and grants in fields of semiconductor physics, magnetoelectric phenomena, ultrasonic vibrations, thermoelastic phase transformations, etc.

Scientific directions of the Institute:
- study of the impact of concentrated energy flows on condensed media and physical processes;
- development of methods and technologies for obtaining materials for functional and special purposes.

Under the State Scientific Institution “Institute of Technical Acoustics of the National Academy of Sciences of Belarus”, a branch of the Republican Center for Technology Transfer was established, the main activities of which are:
- support for innovation and technology transfer in the field of using concentrated energy flows (ultrasound, laser radiation, high frequency electromagnetic fields, ion-plasma flows, high-temperature synthesis) on the structure and properties of condensed media; synthesis of new composite, structural and ceramic materials with specified physical and mechanical properties in an ultrasonic field; metal processing by thermal methods, pressure and powerful ultrasound; development of new instruments and equipment, creation of new information technologies;
- promoting the development of innovative entrepreneurship and expanding international partnerships in the field of innovation of scientific developments;
- assistance in the implementation of state policy in the field of small and medium-sized innovative businesses in the creation of new technologies, the development of new instruments and equipment.

The Institute established the Republican Center for Ultrasound Technologies, which is an interdisciplinary scientific and technical center (cluster) of advanced scientific research. The center was established with the aim of developing new highly efficient processes and materials processing devices, creating new functional materials to improve the quality of manufactured products, reduce costs and improve the safety of production using powerful ultrasound. The expected scientific results of the work of the center are aimed at obtaining new scientific knowledge about the impact of acoustic impacts on:
- structure formation and properties of materials;
- technological processes;
- thermoelastic phase transformations in materials with shape memory.

The expected practical results are aimed at mastering new technologies and developing unique equipment with a high export potential.
