The ultrasonic spot welding machine of Changzhou Jiapu mechanical equipment Co., Ltd. can be used for butt welding of thermoplastics, and can also change the welding head according to the needs of customers, and can be used for riveting, spot welding, embedding, cutting and other processing processes. Compared with other traditional processes (such as adhesive, electric welding or screw fastening), it has the advantages of high production efficiency, good welding quality, environmental protection and energy saving. The ultrasonic spot welding machine adopts the imported piezoelectric ceramic to vibrate the crystal with high efficiency and long service life; the original vertical normal temperature circulating self cooling ultrasonic generator has the lowest failure rate in the whole industry; the aluminum alloy casting integral frame ensures the rigidity of the machine body; the gear rack lifting mechanism is easy to operate and precise in positioning; there are two operation modes, automatic and manual, which are convenient for debugging.
