Ultrasonic application involved the assembly of daytime running lights. A clear plastic lens had to be welded to a plastic body with a hermetic seal. The complex 3D shape and class A surface were a challenge to weld. The customer also needed a cost-efficient system that could accommodate many variants for various car models. To solve the problem, technician developed a composite sonotrode separate...

One more ultrasonic application involved bonding pressure-balancing membranes to pump housings. The housings are made of glass-fiber-reinforced polyphenylene sulfide (PPS). The membranes are made of polyester or polycarbonate. The customer wanted to replace expensive precut single membranes with less costly membrane tape. This was a demanding application, because three consecutive ultrasonic proce...

In one application, ultrasonic was tasked with welding aluminum-coated insulation panels for the engine compartment. The material combination was a killer: Aluminum-coated polyurethane (PU) acoustic mats had to be bonded to glass-fiber reinforced polypropylene (PP) panels. If that wasn’t enough of a challenge, six different parts had to be welded. This application represented a real challenge for ...

Ultrasonic welding is widely used in the automotive industry. Applications range from interior components (side door trim, center console) to engine compartment components (cylinder head cover, engine covers), to lighting, filters and acoustic foams. Welders can be operated immediately without heat-up time. Cycle times are short, and energy consumption is low. For the process to be effective, the ...

Ultrasonic horn definition   1. What is the ultrasonic horn: Ultrasonic horns are a generic term for all ultrasonic transmitters and are an integral part of ultrasonic welding equipment. Its function is to couple the ultrasonic waves generated by the transducer into the object being processed. Because it is to transmit ultrasonic waves, the welding head must work in a resonant state, tha...
