Ultrasonic punching and welding machine Processes

A punching and welding machine is a multi-functional industrial system that integrates material punching  with welding into a single automated process. It’s designed for high-efficiency production of plastic components that require precise shaping and reliable assembly.

This type of machine is widely used in automotive interior manufacturing, electrical enclosures, and plastic product assembly.

Place the bumper bracket on the fixture, punch holes according to the designed hole positions and diameters, then move into the welding area where the welding device will weld the bracket following the predetermined welding path and parameters.
