Description:

The basic principle of ultrasonic assembly is to convert the electrical energy into high-frequency mechanical vibration by expanding and contracting the converter, usually lead zirconate titanate, at the same frequency.This vibration is amplified by a booster and transferred to the workpiece through a shaped tool, or horn, in the form of reciprocating longitudinal motion. Parts being assembled are clamped together under moderate pressure, at which point ultrasonic vibrations force the parts to impact against each other at a preset frequency creating a molecular bond equal to or above the material strength of the parts.

Infinite and accurate combinations of weld time, distance and energy, established through a microprocessor, provide repeatable control of the process, and lend to the full automation of the assembly. Statistical process control and reporting are also possible with some models.

Application:

Ultrasonic is not limited to only thermoplastic materials. An ultrasonic assembly process can also be used to install threaded brass inserts into molded plastic bosses; stake plastic bosses over metal plates or printed circuit boards; swage over standing walls to entrap another component; perform continuous line seals on thin films and fabrics; seal the ends of collapsible squeeze tubes; accomplish perimeter seals on clam shell packages; spot weld corrugated plastic sheets in the manufacture of boxes; and much more.
