The multi-head parallel ultrasonic plastic welding machine has multiple heads standing side by side. Long, curved, large-area plastic parts cannot be welded at one time with a low-power ultrasonic welding machine. This equipment will effectively solve the above problems. This machine can combine two ultrasonic molds to weld products at the same time, greatly improving production efficiency. The functions of the double-head parallel ultrasonic plastic welding machine and the linkage ultrasonic welding machine are very powerful and are one of the most ideal equipment for many electronic manufacturers. Japanese ace steel amplitude transformer, sturdy and durable. The whole machine is gravity cast, with high precision and beautiful appearance. The frame is welded with bent profiles, with an extended table and high stability. The equipment maintains good stability and can ensure consistent welding effects for multiple products at the same time. Applicable to: drying drums, ink cartridges, car dashboards, headlights, taillights, car filters, etc., large-scale product welding, the double-head parallel ultrasonic plastic welding machine has a wide range of uses, and can also weld small products.
