Stapla ultrasonics Corporation.: When bonding material through ultrasonic welding, the energy required comes in the form of mechanical vibrations. The welding tool (sonotrode) couples to the part to be welded and moves it in longitudinal direction. The part to be welded on remains static. Now the parts to be bonded are simultaneously pressed together. The simultaneous action of static and dynamic forces causes a fusion of the parts without having to use additional material.

Sonics: Ultrasonic, Vibration, Spin, Hot Plate, & Heat Staking equipment for the welding, joining and fastening of thermoplastic components, textiles and other synthetic materials.sonics uncompromising philosophy and commitmentto quality has led us to a position asa world leader in the design,manufacture and distribution of ultrasonic welding

TWI WORLD CENTRE FOR MATERIALS JOINING TECHNOLOGY: Ultrasonic welding involves the use of high frequency sound energy to soften or melt the thermoplastic at the joint. Parts to be joined are held together under pressure and are then subjected to ultrasonic vibrations usually at a frequency of 20, 30 or 40kHz. The ability to weld a component successfully is governed by the design of the equipment, the mechanical properties of the material to be welded and the design of the components.

EWI WeldNet: When a rubber ball is dropped, it never bounces back to its drop height because some of the potential energy is converted to heat and sound. This type of process is involved in ultrasonic welding. Instead of a ball, a small projection(s) in the weld zone is flexed by an oscillating force at rates of 10,000 to 70,000 times per second (kHz). This causes the projection to melt and flow across the joint to create a weld. A metal tool (horn) that is oscillating vertically contacts the plastic part at a distance from the projection and is the means for delivering the energy. The part on the other side of the joint area rests on an anvil, ensuring the energy is spent in the weld zone. Frictional heating can also occur to some extent because transmission of the energy through the plastic parts is very complex.

Branson Ultrasonic Corporation: Rotary systems enable simple automation for increased production and efficiency. Branson Ultrasonics Corporation's new Series 40 Welding System is a self-contained semiautomatic ultrasonic plastics assembly platform with the emphasis on configurablity as well as increased production rates.It is capable of welding, staking, inserting, swaging, or spot welding thermoplastics. Automatic cycling and air eject keep the operator's hands free for loading. With only a few minutes of training, an operator can turn out high-integrity, high-volume thermoplastic assemblies.

Dukane Corporation: Dukane is a major supplier of high-performance Ultrasonic, Vibration, Hot plate, Spin and Thermal welding systems. Ultrasonic systems are offered for food cutting and high-end precision metal welding of delicate electronic assemblies.

The Ceramic Expert: Ultrasonic welding takes advantage of the physical fact that friction generates heat. When two preforms are pressed together at their connecting surfaces and excited using high-frequency ultrasonics, the surfaces of the two parts to be joined heat up so much that their connecting surfaces fuse together. This functions with both metal parts and plastic parts.

Toman Tool Corporation: Consistent and correct amplitude is one of the most important factors in achieving a high-quality ultrasonic weld. The Amplitude Gage makes measuring and setting that amplitude easy.

Hielscher - Ultrasound Technology: Ultrasound-supported cutting and welding offers remarkable advantages compared to commonly used processes. The necessary cutting forces are reduced by approx. 75%. The cutting speed and the related productivity of the cutting process are considerably increased. In contrast to the thermal processes, during the ultrasonic welding the sonotrode remains cold, which augments the bonding quality and cycle period. Dr. Hielscher GmbH has specialized in the continuous cutting, welding respectively in the combination of both cutting and welding of films and plates.
