Ultrasonic Staking Of Thermoplastic Assembly

Ultrasonic Staking Of Thermoplastic Assembly

Today ultrasonic welding is used in every industry that processes plastics. Most common uses are in the Automotive, Medical, Textile, Food, Plastics, and Packaging industries.

Ultrasonic Staking Of Thermoplastic Assembly


The basic principle of ultrasonic assembly involves conversion of high-frequency electrical energy to high-frequency mechanical energy in the form of reciprocating longitudinal motion which, when applied to a thermoplastic, generates frictional heat at the plastic/plastic or plastic/metal interface creating a localized melt.

In ultrasonic staking, also referred to as ultrasonic “heading” or “riveting,” the controlled flow of the molten plastic is used to capture or retain another component, usually of a different material, in place. Ultrasonic staking provides an alternative to welding when the two parts consist either of dissimilar materials which cannot be welded, or when simple mechanical retention of one part relative to another is adequate (i.e. as distinct from molecular bonding).
