At present, the domestic three-piece cans are mainly made of traditional resistance welding. There are not many laser welding applications. When these conventional welding processes are used to weld metal packaging containers, the heat-affected zone is large since the energy density is not so large and the heat source area is large. After the welding of tinplate, due to the influence of high temperature of welding, an iron strip with no protective coating and plating will be formed on the inner...
The traditional production method of metal packaging cans is: first, the metal blanks are cut into squares, then the blanks are rolled into cylinders (ie, cylinders), and then the formed longitudinal bonding wires are soldered to form side sealing, one of the cylinders. The ends (ie the bottom of the tank) and the round end caps are mechanically flanged and rolled (ie double crimped seams) to form the can body; the other end is closed after the product has been filled. As the container is...
The can-products that we currently see in the market (such as Coca-Cola, Sprite, and Pepsi) all have something in common: First, they are made entirely of aluminum sheet; Second, they are divided into can bodies and can lids. The lid consists of a round aluminum sheet and a pull tab. These products are called Two Pieces Can. 1. Can making process (1) Unwind and lubricate The aluminum plate of the reel is pulled apart, and the lubricant is sprayed on the stamping surface to ensure good sliding...
As one of the four major packaging materials, metal packaging materials occupy an important position in modern packaging materials. In general, metal packaging materials have the following advantages.

First, the introduction of micro-crimping Since the 1960s, the market for metal packaging containers has been dominated by other non-metallic packaging containers. However, because metal materials have certain mechanical properties that cannot be possessed by other packaging materials, such as high strength, high hardness, high barrier property, and high heat resistance, metal containers have always been active on the stage of packaging products. The production volume is second only to paper...
Metal materials are one of the earliest traditional materials discovered and used by humans. In China and some developing countries, metal materials still dominate the material industry. Metal materials are one of the four major packaging materials. The main types of materials are steel, aluminum, and molding materials are thin plates and metal foils. With the development of modern metal container molding technology and metal plating technology, the development and application of green metal...
Metal packaging materials. Most of the materials we use today are aluminum and iron. Basically, they are derivatives. The characteristics of this kind of packaging materials are first of all durable, because for the metal products, their strength is relatively high. Secondly, they can play a good role in blocking, so that their internal items can not be destroyed, and again, the metal products themselves are easy to process, the fourth is the appearance is more beautiful and more
