28K/40K/35K Ultrasonic Spot Welder for Automotive & Industrial Parts

The ultrasonic welding process is a critical solution for automobile sound insulation and interior components. It is widely used for sound-absorbing cotton on A-pillar guards, B-pillar guards, door guards, middle passages, wheel guards, and engine covers. This technology replaces traditional adhesive methods with high-efficiency, localized welding.

Wide Application Range

• Auto parts: Bumpers, air filters, car audios, foot pads, door panels, clutch forks.
• Electric products: Humidifiers, chargers, storage batteries, telephones, sockets, flash discs.
• Medical products: Leucocyte filters, accurate liquid medicine filters, blood plasma separating cups.
• Packaging & Clothing: Valve bags, paper cups, dairy cases, zippers, woven labels.
• Stationery & Toys: Ink boxes, file folders, name card holders, albums.

The welding principle involves converting 50/60 Hz current into high-frequency electric energy (up to 40 kHz) via an ultrasonic generator. This energy is converted into mechanical vibration, creating friction heat to melt and bond plastic workpieces in less than 1 second.
