The industrial process of metal work is on in full display as skilled workers across various industries each do their part to contribute to the final product. The film emphasizes how easily the smallest parts of our daily lives can play a huge role in shaping a global economy. Film starts with a groomsman setting up a newlywed car. The wedding party soon enters the scene as the narrator begins to talk, mainly about the way many things work together to play a part. A tin can become the focus of the film. 2:35 Vintage grocer explains the code on the bottom of the can and starts narrating about a specific customer who’s a regular. They begin discussing the various types of tomatoes. 4:23 A factory setting where workers hand pack the tomatoes that are sold in the grocers. 5:34 A factory owner begins to talk about the process of making tin cans starting with the tin plates used to make the cans. Sheets have enamel coating, and then direct labeling for some. Tin is slit into body blanks and put through a seaming machine that puts them into can bodies, they are then pressed to seal one end. Cans are also tested for leaks with air pressure. Cans are packed and sent out to canneries. 9:00 The narrator moves on to the tin plate at Unites States Steel. They explain the process of making a tin plate. Slabs of steel or softened with 2200 degrees of heat which creates a crust that is broken off and removed, put through roughing stands and moved to the finishing stand, with each process making the slab longer and thinner. The final runout is 1600 feet where the steel moved out at 25mph and the coiled for processing. A code number is assigned. 12:21 Rolls are cleaned processed, thinned and tested. Coiled again at a mile a minute and is now 13,000 feet long. The rolling hardens the steel and softened through electrolytic cleaning and placed under a furnace. Coils are welded together end to end, moved down a line for further cleaning. The steel is now too soft, so a temper mill gives it the finish required to make it industrial grade. 15:57 Tin is now added through the hot dip process where the steel plates are coated with heavy tin. Another method is another electrolytic process where coil ends are again welded together. The welding operation shows loops of 60ft pits feeding the line. The steel is run through cleaning tanks before being sent to plating cells. An illustration is shown to explain the process. This allows a more flexible process for selecting how much tin is placed on whatever side requires it. 19:00 The tin plate is cut into sheets after being measure for variations in thickness. Plates go through final check and are then packaged to be shipped out to canaries and other consumers around the world. Overseas packers require special packaging. Where do the slabs of steel come from? 21:40 Iron ore is brought in by barges along with coal and limestone which are all shipped to make the steal in a blast furnace. The materials must be tested and sorted prior to manufacturing, we see the ingots formed out of open hearths. The narrator then talks through the process in a summary of events. 24:00 Various products that can be canned are shown and the way cans have contributed to changing the economy. All types of cans are then shown, and tribute is paid to the team work that goes into making the “Treasure Chest of Steel”.
