Ultrasonic welding mold, that also called ultrasonic welding head, ultrasonic fixture, etc. To make the welding quality is more stable, we suggest that the ultrasonic welding machine, using separate pressure source, because the ultrasonic power amplifier (HORN), also is the power of ultrasonic on the mould, will be affected by voltage and gas pressure.

In the field of ultrasonic welding, the most technical is the design and manufacture of ultrasonic mold horn, because it includes the integration of cover curvature, wavelength, sound speed, heat conduction, material density and machining temperature. The oscillating system of the machine is fixed. If the ultrasonic welding machine is 20KHZ(vibration 20000 times/s)×1500W(power to push the friction displacement), the ultrasonic HORN is sculpted and formed. After the final shape and size are determined, the vibration frequency and amplitude should conform to the no-load amplitude within 20KHZ and 1.2 amperes. This process is to integrate the above technical key points. Digital Ultrasonic Electric Box and ultrasonic lower mold can all be made by the customer. Only when the ultrasonic mold HORN is manufactured, the size and detection of frequency adjustment must be reserved. Because the vibration frequency and current exceed this, the ultrasonic mold HORN will be scrapped and cannot be repaired or repaired, which is the most difficult part. Without this information and experience, the self-made ultrasonic mold HORN is most likely to produce instantaneous overload stress and break the ultrasonic heart oscillators. It is advisable to find a professional manufacturer for this part.
