Ultrasonic Bonding

Ultrasonic Welding

When component assemblies can be adversely affected by the general heating of a components, ultrasonic welding can be used for bond assembly. Ultrasonic bonding is a ‘cold’ joining process that joins metals, plastics and textiles. Ultrasonic bonding directs high-frequency vibrations at two components that are clamped together. This creates a rapid build up of heat at the bonding interfaces that produces a bond in only a few seconds without any significant melting of the base materials.

No adhesives or consumables, such as solder or braze metals, are required. Bonds are produced quickly, normally in two to four seconds, without any heating of the surrounding area. Ultrasonic welding is environmentally friendly, produces no waste, and is economical to use.  Apparel, appliance, automotive, electronics, filtration, home furnishings, medical, and packaging are just some of the industries that use ultrasonic bonding.
Ultrasonic Welding

Aluminum, brass, copper, most precious metals, and nickel alloys can be easily bonded. Ultrasonic bonding also has the advantage of being able to join many dissimilar metal combinations.  Ultrasonic wire welding is superior for several reasons. The ultrasonic method does not require the use of any extra materials. The process is well-suited to bond wire to wire or wire to terminals without fillers or crimping tools. 

Plastics are also readily ultrasonically bonded. Bondable thermoplastic resins are categorized as amorphous or crystalline.  Bondable amorphous resins include: polycarbonate, polyphenylene oxide, polystyrene, ABS, polyetherimide, acrylic, and polysulfone. Bondable crystalline materials include: thermoplastic polyester, nylon, acetal, polyethylene, polyphenylene sulfide, and polypropylene.  A limited number of dissimilar, amorphous thermoplastics can also be bonded together (e.g., ABS and polycarbonate).
