Ultrasonic welding for joining complex parts
Norwood Medical has also developed extensive expertise in ultrasonic welding processes. Ultrasonic welding is a technique whereby high-frequency, ultrasonic acoustic vibrations are applied to components being held together under pressure to create a solid-state weld. It is commonly used for joining dissimilar materials and requires no connective bolts, nails, soldering materials or adhesives necessary to bind the materials together.
Norwood Medical performs ultrasonic welding to join complex medical components. Equipment can be easily customized to fit the exact specifications of the parts being welded. To prepare for the process, the interface of the two parts is specially designed to concentrate the melting process. Ultrasonic welding takes place by enclosing the components between a fixed-shaped anvil and a sonotrode connected to a transducer. A low-amplitude acoustic vibration is emitted, and ultrasonic energy melts the point contact between the parts, creating a joint.
Ultrasonic welding is one of the many processes Norwood Medical has brought in-house to meet our customers’ medical device specifications. Our commitment to quality, innovation and vertical integration enables us to be the first choice in medical manufacturing for the world’s leading medical device suppliers. Of course, the most advanced tools and technology are useless without skilled and experienced operators in place to make the best production decisions. With more than 40 years of experience in the medical device industry, Norwood Medical’s engineers have the expertise to make suggestions to increase the effectiveness of medical components while minimizing production costs.
