Metal tins of traditional producing method is: the iron flat square billet cutting growth first, and then billet rolled into a cylinder (barrel) soldering will be formed by the longitudinal joint line again, form the lateral sealing, a cylinder end (bottom) and circular end cover with machinery method to form a flange and rolling seal (this is known as a double lock seam), to form a body; The other end covers the tank top after loading the product. Because the container is composed of tank bottom, tank body and tank top, it is called three cans. For more than 150 years, this kind of canning method has not changed much, but has greatly improved the degree of automation and machining accuracy. In recent years, the welding seam of the side sealing has been replaced by welding.
A new canning principle emerged in the early 1970s. According to this principle, the tank and the bottom of the tank are a whole, which is made of a circular flat slab, which is sealed in the back of the product, which is the two cans. This tank has two molding methods: press - thin stretch (i.e., punching and drawing) and stamping - repress (deep punching). These technologies are not new in themselves. It was used in the first world war to make shell, and the canning was different from the use of ultra-thin metal and production at a high speed (hundreds of millions of units per year
