Among the many tin cans, we can divide most tin cans into two-piece cans and three-piece cans. So, what is a two-piece can and what is a three-piece can? Let me introduce to you.
1. Two-piece can: The body and bottom of the can are stamped from a piece of iron sheet, and there is no seam. It is also called a stretched can. The lid has three processes: cutting-flashing-winding, and the bottom has four processes, and the material is opened- Flashing-pre-coiled wire-coiled wire. At the same time, wine tin cans are made. Two-piece tin cans come in many shapes. Xi'an wine tin cans, for example, round, square, rectangular, special-shaped, etc.
2. Three-piece cans: three pieces of iron stamped iron cans, the can body and bottom are two pieces of iron sheet joined together, the lid is open material-flashing-coiling; the can body is open material-pre-bending-shearing Angle-forming-buckle bone-punch-back cover. At the same time, the three-piece cans can be divided into many different crafts, including back-covered, buckled-bottom, and hinged ones.
