At present, resistance welding technology has been developing in a rapid speed. Digital, computerized, touch screen, the CAN - BUS, integration control and so on, many of the latest scientific and technological achievements and has been widely used in the resistance welding machine, low cost, high speed, high stability of automatic resistance welding machine has been the favour of people. At home, fully automatic machine is used to import and domestic are divided into two categories:

In recent years, China's import of foreign welding machine is primarily a high-speed machine (speed above 600 cans/min) for cans production line and medium-speed machine (speed above 300 cans/min) is used to spray cans production line, the mainstream models are Swiss soviet-german Nick FBB and AFB series. The fastest at present domestic automatic resistance welder FBB1080 is Swiss soviet-german ROM Nick company production of high-speed beverage and food cans full automatic resistance welding machine, it takes 800 cans per minute (110 mm) high pot, copper wire at a speed of 110 m/min has obtained the title of the world's fastest fully automatic machine is, the current domestic only in hangzhou cofco packaging group co., LTD and tianjin Chen group co., LTD. Has installed and run.

Domestic welding machine mainly medium speed (speed around 300 cans/min) and low (speed below 150 cans/min). The mainstream models is shantou light industry machinery works DO - DOS series.

Real's packaging co., LTD., dongguan city, is located in dongguan city, guangdong province, near guangzhou, shenzhen and other coastal cities, the transportation is convenient, is a specialized production enterprise of various kinds of iron and aluminium easy pull cover. Company main products has three series: drink easy pull cover, aluminum safety edge easy pull cover and tinplate easy pull cover, at the same time,
