Electronics & Precision Plastic Welding Solutions | High-control ultrasonic welding for micro and tight-tolerance components

Intro

Electronic and precision plastic components often feature small geometries, thin walls, and

tight tolerances, making conventional joining methods difficult to control.

For EU and US end-use factories, welding solutions must deliver accurate energy control, 

cosmetic-safe seams, and stable results, even when parts are highly sensitive to heat and vibration.

Our electronics and precision plastic welding solutions are designed to provide low-energy, highly 

controllable ultrasonic welding, ensuring consistent quality for micro components and high-yield 

production environments.

Typical Applications

• Electronic plastic housings and covers

• Precision connectors and clips

• Sensor enclosures and micro housings

• Wearable device plastic parts

• Transparent or thin-wall plastic components

• Small functional plastic assemblies requiring cosmetic finish

Key Challenges

• Tight tolerances leave little margin for welding variation

• Thin-wall parts are sensitive to excess energy and deformation

• Cosmetic defects such as whitening or flash are not acceptable

• Inconsistent energy output leads to unstable weld quality

• High-yield production requires repeatable process control

Solution Highlights

• Low-energy ultrasonic welding control minimizes thermal and mechanical stress on micro parts

• Automatic frequency tracking maintains stable ultrasonic output under varying part loads

• Precision mechanical structure ensures accurate alignment and controlled welding motion

• Optimized horn and fixture design protects cosmetic surfaces and fine features

• Digital parameter control enables precise adjustment of time, energy, and amplitude

Recommended Systems
