Last week, we received two types of medical cleaning brushes from our client. The detailed requirement is to weld the brush to the rod firmly without any overflow. Below are the pictures before welding:
According to the structure of the brushes, part 1 is the metal wire, part 2 is the plastic rod, we analyzed and designed the customized 20kHz ultrasonic welding tool for them, as is shown below:
The lower mold is designed to fix the brush and rod together. The ultrasonic welding mold surface has three needles that are the main parts used for welding.
After the ultrasonic welding mold was designed and produced well, we did ultrasonic welding tests for clients.
The ultrasonic welding results are shown below, we also did the pull test, which eventually met the client’s welding expectations.
