Introduction

This 35kHz ultrasonic spot welding machine is designed for precise welding of

small plastic parts and electronic components, offering fast cycle times, 

stable energy output, and consistent weld quality.

It is ideal for applications requiring localized spot welding in delicate or small-scale assemblies.

Compared to standard ultrasonic welding machines, spot welding systems are optimized for

targeted bonding without affecting surrounding materials.
