30kHz High Speed Ultrasonic Assembly



spot welding


The ultrasonic waves vibrate 10's of thousands of times per-second. This oscillation is transferred to a contact surface that is directly in contact with the plastic parts. Since the boundary of the welding area has a large acoustic impedance, it produces high temperatures. Plastic is a pretty poor conductor of heat and can't dissipate the heat before it changes the state of the plastic from solid to liquid. With a bit of pressure applied, this makes the two parts blend together as if they are a single piece of plastic. Once the ultrasonic signal is stopped, the parts become solid again. This is the magic that creates a weld between the two parts that is clean and very strong. The weld will have a strength that is close to that of the raw materials being formed together in an injection molding process.
