28K 900W Ultrasonic spot welder for pvc umbrella
It does not need flux and external heating, does not deform due to heating, has no residual stress, and does not require high pre welding treatment on the surface of weldment. Not only the same metals, but also dissimilar metals can be welded. Thin plates or wires can be welded to thick plates. The energy of ultrasonic welding good conductor is much less than that of current welding, which is often used in the welding of transistor or integrated circuit lead. When it is used for the seal welding of drugs and explosive materials, it can avoid the contamination of drugs due to dissolved objects in general welding, and it will not explode due to heating, etc.
