Metal Packaging boxes have many advantages over plastic packaging, not only are they healthy and environmentally friendly, but they also have a beautiful appearance that attracts many customers. Today we will talk about the processing of Metal Containers. The key is curl forming and welding side seams. The side seams are sealed by tin welding, gluing and fusion welding.
The latest welding machine uses a small lap volume, the metal temperature is just below the melting point, but to increase the welding roller pressure, the two lap surfaces will be forged and pressed together. The weld destroys the original or painted smooth surface of the inner surface, leaving exposed iron, iron oxide and tin on both sides of the weld. To prevent contamination of the product and erosion of the weld seam by the product, in most cases the side seal of the metal can needs to be protected with a coating. The side seal of a metal can containing only dry products can be glued, i.e., the longitudinal seam is attached with nylon tape, which melts and solidifies after the cylinder is formed.
Tin solder cans are generally composed of 98% lead and 2% tin. The cylinder making machine that rolls the flat slab into a cylinder is used in pairs with the side seam sealer that performs the tin soldering. the cylinder of Metal Cans is made in a machine where the edges of the slab are cleaned and bent into a hook shape so that it can be easily fixed when forming the cylinder.
The cans are then passed through the side sealer, solvent and solder are added, the sealing area is preheated with a gas lance, and the solder is further heated through the longitudinal solder rollers so that the solder flows all over the seam, after which the excess solder, mainly in the form of drops, is removed with a rotating scraper. The fusion soldering method is a resistance soldering process using the self-consuming wire electrode principle. Earlier fusion welding systems used large overlaps to raise the temperature of the steel to the melting point and weld at lower roller pressures.
