About Ultrasonic Welding
For Assemblying Of Medical Components
Assemblying Medical Devices can be a
challenge since they are made up of different thermoplastic
materials and frequently require hermetic seals. The Disposable
nature of the products requires that costs are minimal. Medical
devices are often assembled from several components.
Ultrasonic welding offers a solution
to these problems. Ultrasonics can be used to join plastic parts,
insert metal fasteners in thermoplastic materials, form plastic
rivets, degate plastic parts, and cut and seal films and fabrics.
Ultrasonic welding can be used to assemble a variety of medical
devices, including liquid-bearing vessels, intravenous components,
IV components, Cannula, Filters, Diagnostics, Surgical mesh,
hearing aids, filters, monitors and diagnostics components.
Ultrasonic bonding is also used to assemble nonwoven textiles for
such items as medical gowns, boots, caps, face masks, hygiene
products, incontinence products, bed protectors, surgical drapes,
pillow covers and filter media.
During ultrasonic welding, high
frequency vibrational energy at the interface of two plastic parts
causes the material to soften and flow in a fraction of a second.
When the material is pressed together and it resolidifies,
the bond is made. No glues or solvents are needed. Heating is
confined to the interface are so that the assembled parts are not
too hot to handle immediately after welding.
