Custom ultrasonic welding fixtures and molds are precision tooling components used to 

support, locate and secure plastic parts during ultrasonic welding. They help ensure stable

 energy transmission, accurate alignment and repeatable welding quality for demanding

 industrial applications.

TIMEAST designs and manufactures custom ultrasonic welding fixtures and molds for 

automotive, electronics, medical and industrial plastic assemblies. Each solution is 

engineered according to part geometry, welding frequency, material characteristics

 and production requirements.

What Are Ultrasonic Welding Fixtures and Molds?

Ultrasonic welding fixtures are used to hold and position workpieces accurately 

during welding, while molds are designed to match part geometry and improve

support under vibration. In many applications, the fixture and mold work together

to reduce deformation, improve welding consistency and increase production stability.

Custom Ultrasonic Welding Mold Solutions

TIMEAST provides fully customized ultrasonic welding molds based on customer drawings, samples,

 or technical requirements. Each mold is engineered to match the welding frequency, product structure, 

and material characteristics to achieve optimal

welding performanceWe support ultrasonic welding molds compatible with 15kHz, 20kHz and 35kHz 

ultrasonic welding systems, ensuring precise alignment between the horn, workpiece, and fixture.
