Ultrasonic Welding Head

The main function of ultrasonic tool head is to transmit ultrasonic vibration to the workpiece. The material of Ultrasonic Welding Head is usually aluminum alloy or titanium alloy. These two metal materials have better uniformity and can withstand long-term and repeated vibration. Generally speaking, when used in polymer processing, aluminum alloy cutter heads have wide applicability and low price. The fatigue strength of titanium alloy is more than twice that of aluminum alloy, so it is suitable for higher power, but it is expensive and difficult to manufacture. Because ultrasonic vibration will lead to sliding between the mold and the polymer substrate, reasonable fixture design is very important to the success or failure of ultrasonic welding.

FAQ：

Q：How to process the Ultrasonic Welding Head of ultrasonic plastic welding machine？

Give out the drawing first, make it out to measure the frequency, and then fix the frequency to the frequency you want

Q：Is the welding head of ultrasonic welding die aluminum alloy or titanium alloy？

Generally, if there is no special requirement, only aluminum alloy or steel is used, because the cost of aluminum alloy or steel is lower than that of titanium alloy.

Q：Difference between ultrasonic welding full wave head and half wave head？

Different tool heads are required for different welding objects. No matter near-field welding or transmission welding, only half wavelength tool heads can make the welding end face reach the maximum amplitude. There are two kinds of tool heads, one with amplitude amplification and the other without amplitude amplification. The acoustic system tool head for plastic welding machines is usually made of aluminum alloy. Its end face is plated with hard alloy. When the power is high, it can also be made of titanium alloy. The fatigue strength of this material is more than twice that of aluminum alloy.
