The reason why the metal tank adopts the rolled edge process is mainly based on the consideration of its excellent sealing performance and enhanced structural strength. The edge is rolled, that is, the edge of the metal plate is rolled into a ring. This process can not only ensure the sealing of the metal tank during transportation, storage and use, prevent liquid or gas leakage, but also significantly improve the overall strength of the tank. The realization of the edging process includes multiple steps such as pre-processing, edging machine edging, and fusion welding or sealing treatment. Each step is finely controlled to ensure the quality of the final product. In addition, the rolled edge design also gives the metal can a smoother and more beautiful appearance, and is convenient for automated production, reducing costs and improving efficiency. In summary, the edging process plays a crucial role in the manufacture of metal cans and is the key to ensuring the sealing, strength and aesthetics of the product.
