Basic requirements for making tin cans

Tin-plated iron cans are made of tin-plated iron. It has been widely used in the market, especially in shopping malls, supermarkets and other places where people are mostly crowded. It is used as a packaging form for beverages, beer, and wine. The production of tin cans is favored by people because of its low cost, fine printing, non-toxic and harmless, strong corrosion resistance, good metal luster, and convenient portability. Tin-plated iron has an effect on the flavor, color and taste of food (red wine/glucose wine) It has a good preservation effect, and the exquisite tin box pattern can also play an advertising role, enhance the visibility of your product brand, and has a very high storage and convenient use value.

Requirements for making iron cans:

1. When loading and transporting food and beverage tin cans, the protective film should be wrapped as a whole, including all accessories. The stainless steel iron wine cans are placed on a special saddle-type shelf with soft materials, and they are bound firmly to avoid scratches.

2. The main accessories of food and beverage cans, such as upper manholes, lower manholes, agitators, level gauges, respirators, sampling valves, spray devices, cleaning devices, valves, etc., should be of quality and installation location.

3. The inner and outer surfaces of the iron tank maintain the original color and roughness of the cold-rolled stainless steel sheet, and the surface roughness Ra value of the inner weld is not more than 0.8 . Wine tank containers should meet the requirements of GB16798-1987.

 4. The bottom and cover of the tank should adopt a flanged structure to ensure that the butt joint with the cylinder body is a flat butt type. When the diameter of the tank body opening is not less than 38mm, the inner or outer flange should be used, and the arc radius of the flange should not be Less than 5mm.

Tin can making process

Printing iron →cutting →stamping →packaging →quality inspection

    In the production process of tin cans, the first is to print the iron, the whole sheet is printed according to the design, and then the rectangular iron sheet is cut with a cutting machine, the blank is rolled into a cylindrical shape, and the joints at both ends are welded longitudinally to form a cylindrical shape. . One end of the cylinder and the round end cover are mechanically rolled and sealed, and the other end is put into the finished can cover to form an iron can. The manufacturing method of the iron box is similar to that of the iron can. Since most of the tin cans and tin boxes are composed of three parts: can body, can cover and can bottom, they are also called three-piece cans. Generally speaking, three-piece cans usually refer to tinplate cans. Two-piece cans refer to aluminum cans.
