🔴 A metal can is actually a type of metal container whose outer sheet is made of a combination of a special kind of soft tin-coated steel, and it is also called full drain. Canning industries, contrary to the general public's opinion, are among the specialized and laborious industries that many issues will affect the quality of their products. The inner layer of a metal can is made of a special varnish that makes it suitable for use in some industries such as the food industry.
🔴 In addition to the special varnish used in can making, the type of welding and the method of connecting different components of the can are also very important. A simple metal can consists of three parts: the body, the top plate, and the bottom plate. The body is actually a rectangular sheet, and the top and bottom parts are circular.
🔴 In order for the lid of the metal can to be completely tangentially welded to the body without the slightest seam, a special type of welding by means of heat and powder must be used, and especially for the food industry, it must be done correctly in order not to contaminate the contents. The inside of the can will be very important.
