canning industry

The canning industry is considered one of the most widely used industries and a subset of the packaging industry in the country. You must have come across products that are bought for the kitchen on a daily basis, some of which have plastic or metal packaging. The production of metal cans is one of the things that are produced in the can industry. According to the definition, canning is an industry in which large and small factories and manufacturing companies operate to produce and convert metal sheets into cans of different sizes. The main activity of the factories in these industries is in the field of food.

Application of cans and factors affecting the final price of production

The production of cans in the canning industry is used in industrial and domestic fields, and for this reason, it is considered a very important and necessary industry. Among the products produced in these industries, we can mention cans of tomato paste, canned beans, canned foods, tuna, chemicals, dyes, etc. In fact, without such industries, it will not be possible to maintain them for a long time. Metal cans produced in can factories have different thicknesses depending on their final use. Depending on the type of thickness, the degree of cleanliness of the sheets, the final quality and the shape of the can, their final price is determined.

On the surface, canning industries may seem like one of the easiest and most basic industries; But you will be surprised if we tell you that the precision of the equipment and machines used to produce cans made of coated tin sheet is within a few microns. For this reason, the canning industry is considered one of the precise industries.

The most important cans produced by the canning industry with the application of food and non-food packaging are in two broad categories, two-piece and three-piece. Kensaz canning factory is one of the most prominent in the field of producing all kinds of metal cans. We briefly explain the production method of each: 3-pieces can:
These cans are produced in several ways, which include: Cans produced with welding seam: The body of the can is subjected to the ERW (Electrical Resistance Welding) process after being made. As a result of this process, cylindrical cans are produced. The welding area of ​​the cans is covered both inside and outside with special materials in a uniform form and a very thin layer. Then they are heated in a special furnace to stabilize. Cans produced with laser welding seam: This method was used before and is not common today. In fact, due to the pollution caused by the soldering alloy, this method is obsolete, which leads to poisoning, especially for food packaging. Of course, there are other methods for producing these types of cans, which we did not mention because they are not common in the country's canning industry. 2-pieces Can: These cans are also produced in the canning industry with the help of several methods, which we have explained below: By DI (Drawn & Wall Ironed Can) method: In this method, long cans are produced with different processes, including sheet ironing in the form of stretching. The bottom and body of these cans are made of the same material. Two-piece stretchable box: These types of cans are made with the help of stretching operation. But compared to two-piece DI cans, the tension needed to make them is less. The building materials are poured into the mold and finally a 2-piece can is produced. The material of the body and bottom of the can is also similar.
