Portable Gun Type Ultrasonic Plastic Assembly

Portable Gun Type Ultrasonic Plastic 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.

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.



1. Ultrasonic is the fastest, most repeatable and economical assembly method available to the industry today.

2. With ultrasonic, most thermoplastics can be assembled without heat, mechanical fasteners, or hazardous consumables such as adhesives or solvents.

3. Ultrasonic can join parts - small or large, simple or complex - with lower reject rates than any other method.

4. Using ultrasonic, labor - both as a skill factor and as a time factor - is significantly reduced. And since the equipment can readily be automated, any non-technical operator can be trained in minutes to produce high volume, high integrity assemblies.


Simply put, wherever two parts come together and one of them happens to be a thermo plastic resin. Following is a partial list of some of the industries we serve and the typical applications for our process.

·         Appliance: Fixtures, hardware, and enclosure assembly, welding of components.

·         Automotive: Parts and body components, instrument panels, headlight assemblies, under hood assemblies.

·         Cosmetic: Assembly of compacts and other containers, sealing tubes, packaging.

·         Electronic/Electrical: Component, connector cable and wire harness assemblies, enclosure cases and instrument faces, audio/video cassette and cartridge, switch assemblies.

·         Food: Sealing of pouches, tray containers and fillable fillable tubes; sealing microwavable containers; product packaging.

·         Hardware: Product assembly and blister pack packaging.

·         Health Care: Product containers and accessories.
