Ultrasonic sealing and cutting is the use of ultrasound to metal tube welding, mainly in copper, aluminum tubes, mainly used: air conditioning, water machine, refrigerator compressor inlet tube sealing; cut-off valve, expansion valve and Brass Seal; superconducting heat pipe flat plate solar water heater tube sealing; all kinds of vacuum device vacuum sealing.Ultrasonic sealing and cutting the advantages: short welding time, does not need any flux, gas welding, solder; no spark, fast and environmental safety.
Buying ultrasonic sealing and cutting machine should pay attention to the following:
1 for different materials and sizes have strict technical indicators, we take the fridge brass to illustrate: Fridge Brass by φ 6mm, wall thickness 0.75mm brass, ultrasonic welding thinnest should control in 0.8-0.9mm.2 high quality welding machine with two ultrasonic amplitude control function, a period for the compressed, a period for welding.Application of 3 in the refrigerator, the welding head life must be more than 30000, in some extreme conditions, we can do 200000 times in the head.
