    High Power 20KHz Ultrasonic Welding Transducer For Plastic ...
    An ultrasonic plastic welding transducer is a core component that converts high-frequency electrical energy into mechanical vibrations to join plastic parts. It works with a generator that provides the electrical signal, which is then amplified by a booster and transmitted to the horn, causing high-frequency vibrations that create friction and heat to fuse the plastic. Common frequencies are 15 kHz, 20 kHz, 35 kHz, and 40 kHz, with power, frequency, and other parameters often customizable for specific applications. 
    How it works 
    • Converts electrical to mechanical energy: The transducer, often a piezoelectric ceramic device, takes a high-frequency electrical signal from the generator and uses the piezoelectric effect to create mechanical vibrations.
    • Transfers and amplifies vibrations: It transfers these vibrations to a booster, which can amplify the amplitude of the mechanical vibration.
    • Delivers to the workpiece: The amplified vibrations are then sent to the horn, which focuses them onto the plastic parts to be welded.
    • Fuses the plastic: The high-frequency vibrations cause friction at the contact point between the plastic pieces, generating heat that melts the plastic and creates a strong, permanent weld upon cooling. 
    Key characteristics 
    • Frequency: Common frequencies include 15 kHz, 20 kHz, 35 kHz, and 40 kHz, chosen based on the application.
    • Power: Power ratings can vary significantly, from a few thousand watts for smaller applications to over 4000 watts for high-power or large-area welding.
    • Material: Often constructed with robust materials like titanium and aluminum for durability.
    • Customization: Transducer specifications, such as capacitance, resistance, and power, can often be customized to meet specific application needs.

    What is the function of transducer in ultrasonic welding?
    The transducer, also known as the converter, converts the electrical energy from the generator to the mechanical vibrations used for the welding process. It consists of a number of piezo-electric ceramic discs sandwiched between two metal blocks, usually titanium.

    AI Overview
    Ultrasound transducer | Radiology Reference Article ...
    In ultrasound, the transducer is the device that emits high-frequency sound waves into the body and receives the echoes that reflect back, converting them into electrical signals to create an image. It functions as a transceiver, using piezoelectric crystals that generate sound when an electrical current is applied and produce an electrical signal when struck by an echo. The type of transducer varies by shape, size, and frequency, which determines its application and image quality, such as the linear, convex, and phased array transducers.
     
    Function and purpose
    • Transmits sound waves:
      The transducer sends high-frequency sound waves into the body. 
    • Receives echoes:
      It acts as a receiver, capturing the sound waves that bounce off different tissues and organs. 
    • Converts energy:
      It converts electrical energy into mechanical energy (sound waves) and then back into electrical energy (echo signals). 
    • Generates images:
      The electrical signals are sent to the ultrasound machine, which uses the time it takes for echoes to return to calculate distances and generate a real-time image of the internal anatomy. 
    How it works
    • Piezoelectric effect:
      The active element in most transducers is a piezoelectric crystal (often made of PZT). 
    • Transmission:
      When an electric field is applied, the crystal vibrates, producing high-frequency sound waves. 
    • Reception:
      When the sound waves (echoes) return and hit the crystal, they cause it to vibrate, which generates an electrical signal. 
    • Frequency and depth:
      The thickness of the crystal determines the frequency; thinner crystals are for higher frequencies (superficial structures), while thicker ones are for lower frequencies (deeper structures). 
    Common types
    • Linear array transducer:
      Has a flat face and a rectangular image; good for imaging superficial structures like blood vessels. 
    • Convex (curvilinear) transducer:
      Has a curved face, providing a wide, fan-shaped image for deep-penetrating views of organs in the abdomen. 
    • Phased array transducer:
      Uses multiple elements to steer the beam, making it useful for hard-to-reach areas like the heart.
