Ultrasonic Welding Machine

When the ultrasonic wave acts on the contact surface of the thermoplastic plastic, it will produce tens of thousands of high-frequency vibration per second. Such high-frequency vibration reaches a certain amplitude.The ultrasonic energy is transferred to the welding area through the upper welding piece. Due to the high acoustic resistance in the welding area, that is, the interface of two welding, local high temperature will be generated.Due to the poor thermal conductivity of the plastic, it cannot be timely distributed, gathered in the welding area, resulting in the rapid melting of the contact surface of the two plastic, plus a certain pressure, make it into one.When the ultrasound stops, the pressure is allowed to continue for a few seconds to solidify, creating a strong chain of molecules,to achieve the purpose of welding, welding strength can be close to the strength of raw materials.
