Food-borne illness is no laughing matter. In 1985, a listeriosis outbreak in Southern California killed as many as 40 people. The outbreak was eventually traced to a Mexican-style soft cheese contaminated with the bacterium Listeria monocytogenes.

In the continuing evolution within the family of ultrasonic welding and complementary expanding of appliance needs, ultrasonic metal welding as a solution encompasses superior performance, improved throughput and reduced maintenance.

These tips can help you avoid problems with ultrasonic welding.

While the concept of ultrasonic welding is simple, the process of designing a robust joint and developing an effective weld process can be quite complex.

Santa’s helpers depend on adhesives, screws and ultrasonic welding.

In ultrasonic plastic welding, three process variables directly affect weld quality: amplitude, duration and force.

When screws or bolts are threaded directly into plastic components, failures can occur due to stripped threads or plastic creep.

Ultrasonic energy has been used to join thermo-plastics for over 35 years. Ultrasonic welding of thermoplastic materials is by far the most common form of ultrasonic assembly, and is used extensively in all major industries including appliance, electronic and medical.

A lot can happen in 0.5 second, especially in the world of assembly. One or more rivets can be simultaneously inserted. Multiple beads of adhesive can be dispensed. And two thermoplastic pieces can be ultrasonically welded into a usable part.

More than 30 years after the Tylenol tampering case—in which seven people died in Chicago and surrounding suburbs—prescription drug safety remains critically important and an ongoing challenge for pharmaceutical manufacturers.
