Ultrasonic Plastic Welding FAQ
What materials can ultrasonic plastic welding machines join?
Ultrasonic plastic welding is commonly used for thermoplastics such as ABS, PP, PE, PC, PA, PS and POM. Final weld quality depends on material compatibility, joint design, wall thickness and process settings.
How should I choose 20kHz, 35kHz or 40kHz ultrasonic welding?
20kHz is often used for larger or stiffer plastic parts, while 35kHz and 40kHz are commonly selected for smaller, precise or cosmetic assemblies. Frequency should be matched to part size, weld area and strength targets.
What is the difference between servo and pneumatic ultrasonic welding machines?
Servo ultrasonic welders provide tighter control of depth, force, speed and process data. Pneumatic welders are cost-effective for standard plastic assemblies and common batch production tasks.
