This is appropriate for metals, woo fabrics and plastics. A great benefit that you get with ultrasonic welding is that it can be utilized on non-metal materials, such as thermoplastics. A horn pushes against the parts being joine applying pressure and energy until they fuse together. Consider ultrasonic welding whenever the design calls for.

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. Metal with a thin section can also be welded with USW. This method is most commonly used to join thermoplastics and in joining materials that are similar and does not require any bolts, nails, soldering material or adhesives that are needed to join the materials together.

This frictional heat is applied through high speed vibration generated in a sonotrode and delivered by a welding “horn. Using a welding tool called a sonotrode , the high-frequency vibrations generated by the ultrasonic system, in combination with pressure, are transferred to the parts to be joine which leads to relative vibrations in the jointing zone. The process is based on a conversion of friction and vibration energy into heat. It is a solid state welding process. In the ultrasonic stack, the converter transmits the energy through the booster causing the horn to vibrate.

The ultrasonic welding process converts electrical energy into mechanical vibrations causing the plastics to join. There are many good reasons for that: This sustainable and clean technology requires no additional materials (adhesives) or expensive time-consuming processes such as pre-treatment and drying. Choose the perfect machine from over 200listings. Components joined by ultrasonics provide high strength and excellent electrical conductivity, since the vibrations destroy oxide layers and remove impurities on the metal surfaces. Welding parameters.

There are a number of parameters that must be selected correctly in order to achieve good ultrasonic welds. For this article, the amplitude and welding modes are considered. Compared with other welding methods – which include heat staking, hot plate welding , spin welding , and vibration welding – ultrasonic welding offers.

Servo-controlled ultrasonic metal welding allows our customers the ability to change applied force and amplitude during the welding process with multi-step welding. Turning these once-static parameters to dynamic, changeable options gives users the ability to apply optimum weld parameters throughout the entire weld process. Learn the science behind this welding technique and its applications.

As a rule, the direction of force and vibration is parallel to the joint surface. Here is an example: A kHz converter produces amplitude of. An ultrasonic horn with a gain of 2. In addition to welding , ultrasonic energy is commonly used for processes such as inserting metal parts into plastic or reforming thermoplastic parts to mechanically fasten components made from dissimilar materials.

In ultrasonic welding , ultrasonic vibrations create a friction-like relative motion between two surfaces that are held together under pressure. The motion deforms, shears, and flattens local surface asperities, dispersing interface oxides and contaminants, to bring metal-to-metal contact and bonding between the surfaces. These advantages have been made possible thanks to an ever more accurate research of the employed materials, machinery design and the necessary tools. The welding time is usually about less than 1sec. Applications range from exterior parts (front and rear bumpers), interior components (seats, side door trim, center console, insulation cotton) to engine compartment components (water chutes, battery covers, cylinder head cover, engine covers), to lighting, filters and acoustic foams.

A solid state welding process in which coalescence is produced at the faying surfaces by the application of high frequency vibratory energy while the work pieces are held together under moderately low static pressure. Our ultrasonic welding services will create a bond or joint area which is extremely precise. Our state-of-the-art equipment ensures every joint will be exact, which is essential for many industries and applications.
