1. Steel strip arrives at the can manufacturing plant in large coils.
金屬板材以大卷的形式運到制罐廠
2. Steel strip is cut into large sheets
卷材被切成大的片材
3. Lacquer is applied to the side of the sheets that will become the internal surfaces of the finished cans. This special lacquer is to protect the can itself from corrosion and from any possibility of interaction between the contents and the metal.
在將成為罐體內表面的一面涂漆，涂漆是為了防止金屬本身銹蝕或與內容物發生反應
4. The lacquered sheets are dried in an oven.
漆膜經過烘道干燥
5. The large sheets are slit into small sheets, one for each can body.
片材被分成小塊，每一小塊做一個罐身
6. Each small sheet is rolled into a cylinder.
每個小片被卷成一個圓筒
7. The cylinder edges are welded by squeezing them together whilst passing an electric current through them. This heats up the metal sufficiently for a sound joint to be made.
卷筒的二邊擠壓在一起通過電流，這會加熱金屬表面并把二邊金屬牢牢地焊接在一起
8. The inside surface of the weld is sprayed with lacquer and then cured by blowing heated air on to the outside of the cans.
罐內壁進行噴涂并在罐外吹熱風使之干燥
9. The cans are passed through a flanger where the top and bottom of the can are flanged outwards to accept the ends.
罐身通過一個刮板使罐頂和底部形成折邊以便與罐底結合
10. Plain ends are seamed to the can bodies to close one end of every can.
每個罐身都與一個罐底卷合
11. The cans are passed through a beader where the walls of the cans have circumferential beads formed in them to give added strength.
罐子通過一個滾邊機給罐身滾筋以增加罐身強度
12. Every can is tested at each stage of manufacture.
At the final stage they pass through a pressure tester, which automatically rejects any cans with pinholes or fractures
每個生產環節都對罐子進行檢測。最后罐子通過一個壓力檢測機，并自動剔除有針孔或爆裂的罐子
13. The finished can bodies are then transferred to the warehouse to be automatically palletised before despatch to the filling plant.
成品罐體運往倉庫并自動碼垛等待運往灌裝廠
