Now with the environmental protection requirements and the improvement and diversity of the working environment, many air-conditioner refrigerator manufacturers have used new processes for the sealing of copper pipes after liquid filling. the traditional process uses copper electrode flame welding. There are some requirements on site, some harmful gases will be generated after welding, and there will be some health effects on the long-term operation of the workers.
Portable pressure-preserving copper tube ultrasonic sealing machine is a special application of ultrasonic metal welding machine. It is used to compress the sealing copper tube by welding tooling, and the copper tube is fused together by instantaneous friction. The production efficiency is fast and can be 6~12MM. The copper tube aluminum tube is sealed, and the general sealing process is within 1S. It is suitable for high-volume production type air-conditioner refrigerator enterprises. The equipment adopts suspension type fixing, which is convenient for welding movement. The copper tube sealing does not need any auxiliary materials, and is environmentally friendly and reliable. Fluorine-filled copper tube sealing strength can reach more than 1500N, meeting 99% of the sealing requirements, this equipment is now the first choice for mass production portable.
