Ultrasonic welding machines' quick, clean process uses high-frequency vibrations and pressure instead of heat to melt and weld plastics, which provides many benefits. Ultrasonic welding, the preferred choice in plastics welding, is perhaps the most rapidly developing field in the industry. It uses high-frequency vibrations and pressure - not heat - to melt plastic pieces together. By creating frictional heat that melts plastics, these ultrasonic welding machines are used weld small- and medium-sized pieces of plastic. When the vibration stops, the plastic quickly cools and becomes solid again. There are many benefits of electronic welding, including that the process is quick and repeatable. Further, the process does not "consume" any additional materials, which means it does not require screws, nails, bolts, soldering materials, glues or other adhesives. Ultrasonic welding machines may even be used to create hermetic seals, because the finished pieces are so strong and clean. An added benefit is that no ventilation system is required because no heating is involved. It is through pressure and high-frequency mechanical vibrations (15 kHz to 40 kHz) that plastic is melted into a solid-state weld. Most preferred ultrasonic welders run at 15 kHz, 20 kHz, 30 kHz and 40 kHz frequencies. The ultrasonic process begins with two thermoplastic pieces that have similar melting points. They are placed together, one atop the other, in the ultrasonic welding machine. Then, high-frequency vibrations are applied directly to the joint being welded. With the vibration application concentrated in the joint itself, the process melts the joint but not the base materials. When the plastic melts, the vibration is stopped and pressure is applied - and the plastics are melded. Because the process is as fast and efficient as it is, weld times are sometimes less than a second. The ultrasonic welding process has become invaluable to many industries. They include the automotive, cosmetic, computer, appliance, toy, medical, electronics, textile, packaging and food industries. Ultrasonic welding is usually preferred in the medical-supply industry, because the no parts are contaminated by outside materials. Products processed with ultrasonic welding machines can even be used for "clean rooms" in hospitals. One of the most typical uses of ultrasonic welding is in the packaging and food industries, which also count on the contaminant-free, clean, quick process. Now one of the most progressive industrial techniques, ultrasonic welding has come a long way. Ultrasonic waves were first used in the late 1940s, mostly for cleaning. It was in the 1950s that ultrasonic welding was introduced as a way to weld plastics and metals. In 1965, two men - Robert Soloff and Seymour Linsley - were granted a patent for ultrasonic welding. The innovative welding process first started to take hold in the toy industry, and has spread to a growing number of applications every year. Now, some 60 years after its advent, ultrasonic welding has emerged as the leading assembly method for rigid thermoplastics. Ultrasonic welding machines come in many models, including ultrasonic hand guns; bench-top integrated ultrasonic welders; automation ultrasonic actuator heads and modular power supplies; and closed-loop process controls, like energy welding, distance welding, time welding, force welding, automatic frequency tuning and variable-amplitude output control. Microprocessor and standard-time models are available, as are tools of the trade, like ultrasonic horns, fixtures, converters and boosters for all makes, models and brands of ultrasonic welders. Many companies provide plastic assembly solutions, but the best of those companies offer top-notch service and technical support and meet the individual needs of each customer.
