The 15kHz 4200W ultrasonic welding machine is designed for large-sized and thick-wall plastic welding applications.
With low frequency and high amplitude, it provides deep ultrasonic energy penetration, ensuring strong and reliable welds.
This industrial ultrasonic welding system is widely used in automotive, industrial containers, home appliances, and customized plastic assemblies.
A. Low Frequency (15kHz) – High Energy Output
Ideal for welding large, thick, or complex plastic components
4200W High-Power Generator
Ensures stable welding performance and deeper fusion
B. Excellent Weld Strength & Consistency
Reduced defect rate and improved production yield
C. Industrial-Grade Stability
Designed for long-time continuous operation
D. Flexible Integration
Compatible with manual stations, semi-automatic or automated production lines
This 15kHz ultrasonic welding machine is commonly used for:
Automotive air ducts & fluid containers
Large plastic housings and structural parts
Thick-wall plastic tanks and covers
Industrial plastic components requiring high weld strength
Custom oversized plastic welding projects
If your application involves large size, thick material, or high structural strength,
15kHz ultrasonic welding is the ideal solution.

Technical specifications can be customized based on your application.
Compared with 20kHz or higher frequencies, 15kHz ultrasonic welding offers:
Higher amplitude for thick-wall and large parts
Better energy transfer for high-strength joints
Improved reliability for demanding industrial applications
Our engineers help customers select the right frequency and power configuration
based on real welding requirements.
Stronger weld joints with reduced failure risk
Improved production efficiency
Lower scrap and rework rate
Professional technical support from application to commissioning
