What are the application areas of ultrasonic welding heads?

Ultrasonic welding heads are widely used in multiple fields, and any industry that uses ultrasonic welding may use them. Here are some common application areas:

1. Automotive industry: used for connecting automotive components, such as body panels, doors, engine mounts, bumpers, front and rear doors, lighting fixtures, brake lights, etc. With the development of high-grade roads, more and more reflective sheets are being welded using ultrasonic waves;

2. Electronics industry: solderable electronic components, circuit boards, etc;

3. Medical industry: used for making disposable medical devices, surgical instruments, etc;

4. Home appliance industry: capable of welding handheld fluorescent lampshades, TV casings, transparent radio panels, power rectifiers, TV casing screw fixing seats, washing machine sinks and other home appliance products;

5. Packaging industry: can be applied to the welding of plastic packaging and metal packaging, as well as the sealing of hoses and the connection of special packaging straps;

6. Battery industry: For example, the welding of copper foil and aluminum foil in lithium-ion batteries;

7. Consumer/power battery manufacturing field: such as ultrasonic refinement of battery coating particles, welding of multi-layer copper and aluminum foils, as well as wire harness welding of electrical cables and pin welding of power semiconductor IGBTs;

8. Plastic products industry: It can weld panels, headlights, and electronic device shells on lightweight electric vehicles, and is also suitable for welding plastic toys, plastic gifts, and other products;

9. Other industries: play a role in processes such as ultrasonic spot welding, ultrasonic cutting, and ultrasonic forming, such as spot welding metal parts, cutting chemical fiber fabrics, rubber, metal foils, aerospace honeycomb materials, as well as fixing and forming electronic products (such as speakers) and cosmetic products (such as lenses).

In different application scenarios, ultrasonic welding heads need to be designed in various shapes, such as a flat and wide cutting blade shape when cutting rubber, a shape consistent with plastic parts when welding plastic, a textured shape when welding metal, and a round rod shape several times the wavelength when processing liquids. At the same time, the materials used for welding heads are also different, including aluminum, titanium, steel, or powder metallurgy steel.
