Sonics & Materials (UK) Ltd. was formed in August 2004 after taking over the plastic welding business from Kerry Ultrasonic. Benefit from our local machine and service portfolios. Plastics assembly is a fast, clean, efficient, and repeatable process that consumes very little energy. (joint area) so the plastic material will melt and form a molecular bond between the parts. The company is ISO 9001 certified and is consistently in the vanguard of industry innovators. Crucial advantages over conventional thermal processes: With state-of-the-art ultrasonic welding technology, non-ferrous metals, mainly aluminum and copper, can be permanently joined by molecular bonding induced through physical vibrations. Materials are joined by means of locally limited heat generation: Ultrasonic welding ensures maintained functionality of the components and provides continuous process monitoring unrivaled by other processes. It is always the people who make the difference in a company. Ultrasonic Welding is the fastest and most cost effective method used today to join and assemble plastic parts and non-ferrous metals. Ultrasonic welding uses high-frequency vibration to melt and weld plastic. Ultrasonic welding is used in almost all major industries like automotive, electronic and appliances, medical, packaging etc. Ultrasonic welding is whereby high-frequency ultrasonic acoustic vibrations are applied to two components being held together under pressure to create a solid-state weld. There are thermoplastic materials, elastomers, and thermoset resins: Thermoplastic materials are plastics that are processed by heat and are well suited for ultrasonic welding. Find here the answers to most frequently asked questions. Industrial ultrasonics is an acoustic principle. All trade shows, 1261 Hardt Circle • 60103 Bartlett, IL • USA. We explain, the physical mechanism of the ultrasonic technology, which components are required, and which variables are most influential. So how does it work? Our good contacts with universities and associations yield valuable impulses. The … Polyethelene, Polypropylene, Polyester and Nylon are semi-crystalline - much more difficult to weld with ultrasonics. Go to seminar overview, Trade shows are a platform for direct exchange – we show you our latest developments and state-of-the art technology. Herrmann Ultrasonics therefore offers a wide range of solutions for integration of ultrasonic systems and components. Ultrasonic sealing technology has become an established and economic alternative of heat sealing: Laminating without the use of adhesives and embossing without the use of heat? Ultrasonic welding is cost effective and a green technology. Click here for technical project management. Becaus… Ultrasonic welding of plastics is used widely in making electronics, medical devices and car parts. When combined with pressure, friction produces heat & melts the parts at the horn contact point. Find the latest press releases, videos and trade show updates, as well as up-to-date images and interesting graphics. This frictional heat is applied through high speed vibration generated in a sonotrode and delivered by a welding “horn.” Ultrasonic welding machines look similar to spot or resistance welders. Industry-specific ultrasonic solutions, Herrmann products and profound expertise of ultrasonic technology – all brochures and publications. These vibrations are called ultrasound because they are at a frequency above than the hearing capacity of the human ear (greater than 16 kHz). for applications that require high amplitude and a … Worldwide. Some materials can be welded well, some are basically fused, and some are not fused. Ultrasonic welding is the method of joining two parts by converting the electrical energy into the heat energy, It is suitable for the plastics and the metals, It can use high-frequency ultrasonic acoustic vibrations to the materials that are being held together under … Every sonotrode is designed, calculated and carefully documented according to customer requirements: The ultrasonic modules are provided in a flexible modular system and allow for easy integration into packaging machines. Longitudinal vibrations in frequencies of 20 kHz, 30 kHz, and 35 kHz with tool amplitudes between 5 µm and 50 µm are introduced into the plastic materials under the action of force. ABS, Acrylic, Polycarbonate and PVC are amorphous polymers - with little or no crystalline structure, they are ideal for ultrasonic welding. A large number of every-day products are welded using ultrasonics. Kerry Ultrasonics was formed in 1954 and had been a prominent manufacturer of plastic welding and ultrasonic cleaning equipment. It’s about our WHY and an endless journey. Every ultrasonic bonding operation will vary based on the plastic materials being joined, the shape of the workpieces, and other factors. Metal with a thin section can also be welded with USW. It is accomplished by converting high-frequency electrical energy into high-frequency mechanical motion. But it is always the people who are most important. Trade shows are a platform for direct exchange – we show you our latest developments and state-of-the art technology. Ultrasonic welding of plastic materials creates a molecular bond within the weld seam. Click here for sealing of packaging materials. Up to 130 different process reference data are available and can be visualized: Sensors and electrical components are not only used in industrial manufacturing but also in automation engineering or in daily use. Worldwide. 01661446  VAT GB 348675511 Privacy Policy. Ultrasonic Welding (USW)is a welding technique that uses ultrasonic vibration of high frequency to weld the two pieces together. Ultrasonic welding works extremely well with a range of thermoplastics, but some are incompatible with each other or with the process, so choose with care. Ultrasonic plastic welders, spin welders, vibration welders, hot plate and staking / inserting machines are available, as well as custom tooling and fixtures. This is about working together based on our values and about our mission to apply these values in our daily work. It is frequently chosen when parts are too complex or expensive to be molded in one piece. There are thermoplastic materials, elastomers, and thermoset resins: Thermoplastic materials are plastics that are processed by heat and are well suited for ultrasonic welding. Hot Gas (Air) Welding: Hot gas (or hot air) welding, is a technique that uses heat. Ultrasonic welding has applications in many fields including the thermoplastics industry. Wang: Ultrasonic plastic welding uses the piezoelectric ceramic effect to convert electrons into machinery, allowing high-speed friction between the media with similar melting points to generate heat. It offers many advantages, including process reliability and repeatability, lower energy usage than other joining techniques, material savings (because there is no need for consumables, such as glue or mechanical fasteners), and labor savings. © PC, PMMA, and ABS can be welded to one another under certain conditions.
