Ultrasonic Welding Equipment for Multi-Point Plastic Assembly Welding


Ultrasonic plastic welding is suitable for virtually all thermoplastics. When planning welds between semi-crystalline plastic pieces of work, it is important to remember that the weld behaviour of these plastics differs considerably from that of amorphous plastics.

Ultrasonic plastic welding can be used to a limited extent for joining together two different thermoplastics (amorphous plastics). Ultrasonic welding is not suitable for use with thermo setting plastics. 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.


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.

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.
