10 tips of ultrasonic welding machine


 Ultrasonic welding machine is a high and new technology for melting mature plastic products. Ultrasonic welding can be used for various cooked plastic products. When welding plastic products, neither add any adhesives, fillers or solvents, nor consume a large amount of heat source. It has the advantages of simple operation, fast welding speed, high welding strength and high production capacity. efficient. Therefore, the application of ultrasonic welding technology is more and more extensive. Since the use of ultrasonic welding machine is so extensive, what is the necessary common sense of ultrasonic welding machine, the small version introduces ten common sense to everyone.


Common sense 1:


After turning on the power, the ultrasonic welding machine cannot be put into use immediately. Normal ultrasound takes two minutes to test before use.


Common sense 2:


The ultrasonic welding head (upper die) cannot pass the inspection and identification during inspection, please do not continue to use it! Otherwise, burn the valuable parts such as amplifier sensor!


Common sense 3:


Ensure that the supplied compressed gas is dry and clean. Regularly check whether the filter behind the ultrasonic welder is clean (if there is oil, please clean it). Before replacing the ultrasonic welding head (upper mold), check whether there is oxide (usually black or white) at the connection. If it is, please use 800 (or thinner) sandpaper to clean it and clean it with alcohol before installation. During installation, the assembly should be tightened without any looseness.


Common sense 4:


Ensure that the supplied compressed gas is dry and clean. Regularly check whether the filter behind the ultrasonic welder is clean (if there is oil, please clean it).


Common sense 5:


Ultrasonic welding head (upper die) can pass ultrasonic testing, but there is heat during use. No matter how busy you are, you should stop using it and continue to use it until it cools under natural conditions; if there is heat within half an hour to two hours, Make sure to replace.


Common sense 6:


For plastic parts with non-special structures (materials), please adjust the "delay time" to the moment before the ultrasonic welding head (upper mold) touches the plastic parts, and start to emit ultrasonic waves. [If only the ultrasonic system is triggered by the reaction force, please adjust the switch to a low power trigger point.


Common sense 7:


The power supply range should be within 5% of 220VAC. At the same time, the metal grounding wire (usually double grounding) of the shell of the ultrasonic welding machine should be used as much as possible to use a stabilized power supply.


Common sense 8:


When welding plastic parts, if you hear abnormal noise, please stop working. Check the ultrasonic welding head (upper die) amplifier sensor for cracks or good contact. If there is a crack, make sure


replace. If it is loose, please tighten it relatively.


Common sense 9:


Pressing and holding the detection button for a long time is not suitable for detecting the frequency of the ultrasonic mold; when adjusting the frequency, do not press the ultrasonic detection button while adjusting the frequency knob.


Common sense 10:


Each ultrasonic welding head (upper die) needs to adjust its frequency before use. As long as you change between the molds made by yourself, you no longer need to adjust the frequency one by one, but only need to adjust the frequency of starting the mold. During the continuous use of the ultrasonic upper mold, after frequency adjustment and determination, frequency adjustment is strictly prohibited.
