Which plastics can the ultrasonic welding machine weld?Ultrasonic welding machines can weld a lot of materials, but there are not many materials that are really suitable for ultrasonic welding machines. Why do you say this? The following details:The materials that can be welded by ultrasonic welding
1. Ultrasonic Plastic Welding Machine
When ultrasonic acts on the thermoplastic plastic interface, it produces tens of thousands of high-frequency vibration per second. This kind of high-frequency vibration reaches a certain amplitude. The ultrasonic energy is transmitted to the welding area through the upper welding parts. Because the acoustic resistance of the welding area, i.e. the interface between two welding parts, is high, local high temperature will be generated.
The size and shape of the parts that have just been injected change significantly within a few minutes after leaving the moulding machine due to the incomplete solidification, and they are finalized in the cold state. Experience shows that the welding process of parts is different in both cold and hot states.
