Ultrasonic Spot Welding Assembly In Automation

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.Conforming to the spirit of "Service First", ALTRASONIC provides lifetime maintenance to its products for as long as they are used by customers.

Ultrasonic Spot Welding Assembly in Automation


Ultrasonic spot welding is used whenever large plastic parts cannot be placed on a traditional machine. Therefore, the welding head designed as a handgun is brought to the part; either manually or with a robot. The advantage of ultrasonic spot welding is the fact that the parts do not need any special preparation (no energy director required ).Therefore large size vacuum formed parts can also be assembled easily.

The ultrasonic horn is built to produce high amplitude. The tip of the horn is shaped in order to penetrate the two layers of material, leaving a typical ring pattern on the workface, while the backside rests smooth and clean.
