  Ultrasonic welding has applications in many fields including the thermoplastics industry. So how does it work? Ultrasound is a mechanical vibration similar to that produced by musical instruments. These vibrations are called ultrasound because they are at a frequency above than the hearing capacity of the human ear (greater than 16 kHz). In an acoustic assembly, these pressure waves are pro...

  Ultrasonic welding Assembly by energy applicator. Mainly reserved for amorphous thermoplastics. Ultrasound welding is done very quickly (less than 1 second), without adding material.   Ultrasonic spot welding Ultrasound spot welding is particularly recommended for thermoformed parts without an assembly profile, or for parts whose geometry and actual conditions exclude the possibility o...

  Seldom will the ceramic component of a composite transducer have adequate tensile strength to withstand the high mechanical stress associated with the power demands for ultrasonic cleaning applications. The tensile strength of the ceramic elements can be supplemented by mechanically pre-stressing the elements along the direction of polarization. Pre-stress is introduced by incorporating a s...

  As is true in many other applications for piezo¬electric materials, an assembly of multiple ceramic elements offers considerable performance and production advantages in ultrasonic cleaning transducers, relative to a single ceramic element. In order to provide the most efficient operation, simplify manufacturing, and reduce costs, more complex transducers intended for ultrasonic power appli...

  The vibration amplitude curve is shown in the following figure. There is no vibration at node, but the largest stress appears at these points. The machining efficiency is determined by the following factors, 1) Vibrational amplitude of the tool 2) Working pressure to the work piece 3) Condition of abrasive fed to the work piece   Too large working pressure a well as too small pressure ...

  Solder a drilling tool onto the horn   1. Apply a little flux and silver solder onto the end of the drilling tool. 2. Put the drilling tool into position on the horn, and add flux to the joint. 3. Heat the horn with the gas torch, until the silver solder fuses and connects both pieces. 4. Do not heat exactly at the joint of tool and horn, but below on the horn. 5. When the drilling too...

  Definition: Ultrasonic Machining is a non-traditional process, in which abrasives contained in a slurry are driven against the work by a tool oscillating at low amplitude (25-100 microns) and high frequency (15-30 kHz).   Process: Ultrasonic machining is a mechanical type non-traditional machining process. It is employed to machine hard and brittle materials (both electrically conducti...
