ULTRASONIC WELDING / Pocket Innerspring Manufacturing with Ultrasonic Welding

Pocket springs are individual springs placed in little pockets of cloth, tucked under the padding of the mattress top. The individual springs allow for some extra movement in the mattress. A larger number of springs usually translates to more comfort. In manufacturing of pocket innersprings, the springs are placed into non woven textile and this non woven fabric should be sealed. Heat sealing is not enough strong as it destroys the raw material. Instead ultrasoni welding technology is used. Sonikel designs and manufactures, Ultrasonic generator, Ultrasonic converter and Ultrasonic titanium sonotrode for this application.
