Ultrasonic Knife Cutting Plastic – Clean, Precision Edges Without Melting

Product Description

  The principle of an ultrasonic rubber cutting knife is to convert 50/60Hz current into 20, 30 or 40kHz electrical energy through an ultrasonic generator (also known as an ultrasonic power supply). The converted high-frequency electrical energy is converted again through the transducer to mechanical vibration of the same frequency, which is then transferred to the cutting knife through an amplitude modulator device that can change the amplitude. The ultrasonic rubber cutting knife vibrates at an amplitude of 10-70μm along its length, repeating 40,000 times (40 kHz) per second (the vibration of its blade is microscopic, which is generally difficult to see with the naked eye). The cutting knife then transfers the received vibration energy to the cutting surface of the workpiece to be cut. In this area, the vibration energy is cut by activating the rubber molecular energy and opening the molecular chain.

  Ultrasonic cutting is a cutting using the energy of sound waves. It does not require sharp edges or large pressure, and will not cause the edge collapse or damage of the cut material. Ultrasonic rubber cutting knife can easily cut resins, rubber, plastics, fabrics and various overlapping composite materials etc.
