Ultrasonic Replacement Branson 803 Converter for Using 8700 Welding Machine
Description:
Replacement converter for Branson 803 Converter . For use with 187p power supply (with the 801 actuator) and the model 8700 press. The converter is threaded onto a booster, which increases, decreases or just transfers the amount of movement from the face of the converter to the horn or Sonotrode as we call it.
Ultrasonic Converters and Ultrasonic Transducers are one in the same. Converters or Transducers all do the same thing…convert electrical energy to mechanical movement…so we have our electrical charge being introduced across the surface of the ceramics at the desired frequency which in turn gives us a movement or vibration at the working end on the converter.

Ultrasonic plastic welding method:
Because the raw materials, size, shape and welding requirements of plastic welding targets are different, the weldability of plastics is also affected by many factors such as elastic modulus, oscillation resistance, friction coefficient, thermal conductivity and melting temperature. Therefore, in order to improve the quality of plastic welding, a series of ultrasonic plastic welding processes were carried out.
1. Ultrasonic general two-plane welding, in the lower welding surface, a tapered strip running through the entire welding surface is planned to make the energy gather more. For high-hardness welding data with low melting point, the height of the tapered strip shall not be less than 0.25 MM; for low-hardness welding materials with high melting point, the height shall not be less than 0.5 MM.
2. ultrasonic slot casting welding method, the use of distance shift welding to avoid bonding and overheating differentiation. Because the concave and convex surface adheres to a certain gap, the welding difficulty will be added, and the concave and convex surface should be planned to have a certain degree, which lowers the accuracy requirement for casting.
Ultrasonic trimming welder, which is suitable for welding that requires thorough sealing. It is particularly suitable for the welding of crystalline resins such as nylon and high density polyethylene. The welding process is to first melt the contact area at the beginning, and then the controllable downforce of the thousand welding machine gradually melts the remaining portion along the straight face.
3. Ultrasonic soldering method, which is a new welding process in which metal components are embedded in plastics. It replaces the old method of stress-prone injection around metal components. In the insert welding method, the tolerance of the plastic part and the embedded metal is generally about 0.4 mm. In order to add tensile strength, the surface of the embedded metal part can be processed into a streak or a thread type, and several slots can be opened on the outer surface of the metal part. To add strength, you can knurl its axial appearance. Two possible embedding methods, one is to connect the plastic part to the welding head, and the other is to insert the metal into the special joint with the welding head.
4. Ultrasonic welding method, which uses a controlled melting method to process plastic bolts, thereby fixing another part of the assembly. Ultrasonic waves are applied to the top of the bolt so that the molten plastic fills the cavity of the horn to form the protruding cap of the locking element. The welding head should be gently lowered onto the riveting rod to prevent the card from being overpressured and forming an accidental deformation. The most common type of rivet welding, plastic melting is from the top of the horn cavity, the diameter of the horn is generally planned to be double the rivet. For the processing of the diameter of the riveting rod and the wear-resistant thermoplastic, the round cap is riveted. If the appearance and the fastness of the welded component are not high, the knurling and sculpting method can be used. The welding surface is required to be flat and Baidu cannot Excess parts can be statically rivet welded.
