Each set of welding heads and molds produced by ultrasonic mold processing factory, whether standard products or customized according to customer requirements, are made of the best materials and tested repeatedly. After many tests, the shape, strength, audio and other parameters of the welding head can meet the most stringent standards, and the welding head and die can achieve the most perfect match.

Because the ultrasonic welding head of ultrasonic die works under high-frequency vibration, a symmetrical design should be maintained as far as possible to avoid unbalanced stress and transverse vibration caused by the asymmetry of sound wave transmission (the welding head we use for welding uses the longitudinal transmission of ultrasonic vibration. For the whole resonant system, unbalanced vibration can lead to heating and fracture of the welding head. Ultrasonic welding machines are used in different industries and have different requirements for machining accuracy. For particularly thin workpieces, such as the welding of lithium-ion battery pole piece and pole ear, the coating of gold foil, etc., the requirements for machining accuracy are very high. All our machining equipment adopts numerical control equipment (such as machining center), so as to ensure that the machining accuracy meets the requirements.
