Document Summary
There are two different processes for making cans, depending on which design you need for your product. Cans can be made out of either steel or aluminum. Two piece: rectangle formed into cylinder, circle drawn into cup shaped, seal side seam of cylinder cylinder, two metal circles rolled onto ends, one circle needed for top of cylinder. Two piece cans have a little bit more variation, and there are two common methods used to make them. Mechanical cinch seam using machinery to fold excess metal over itself to create a double-layered seam that is pressed together using extreme force. Welded seam utilizing welding equipment to fuse the body of the can and the lid together by heating the metal and having it melt together. Adhesive-bonded (cemented) seam applying an additional layer of hot metal in order to connect the can body and can lid by allowing them to adhere to the layer of adhesive bond.
