How to make Metal Can: A Step-by-Step Guide

Metal cans are popular for packaging various products, including food, beverages, oil, paint, and stationery. They are known for being strong, durable, and customizable, which makes them suitable for different purposes and preferences. But how exactly are metal cans made? What are the steps involved in transforming raw materials into finished products? In this article, we will explain the process of making metal cans and showcase how Aladdin Factory, a leading metal can manufacturer in Vietnam, utilizes state-of-the-art technology and equipment to ensure quality and efficiency.

Making metal cans can be divided into four main stages: sheet cutting, printing, forming, and seaming. Let’s take a look at each stage in detail.

Sheet Cutting

To make metal cans, the first stage is sheet cutting. This involves cutting thin, flexible metal sheets, like tinplate or aluminium, into the desired sizes and shapes for the can bodies and lids. At Aladdin Factory, we use high-speed cutters from Japan that can cut up to 300 sheets per minute. We also test the quality of the metal sheets before cutting them to ensure they meet the required standards for thickness, hardness, and coating.


Printing is the second step in making metal cans. It involves applying colors, designs, and information to metal sheets using ink and printing machines. Different methods can be used for printing, like offset printing, screen printing, or digital printing. Printing enhances the appearance and functionality of the cans, making them more attractive and informative. At Aladdin Factory, UV metal printing machines can print up to 200 sheets per minute. We also use LED UV curing systems for printing that can dry the ink instantly and save energy. We ensure the printing process meets the required colorfastness, resolution, and durability standards.


Metal cans go through three stages to be made, forming the third stage. In this stage, forming machines shape the metal sheets into cylindrical or rectangular forms. The forming process can be done by stamping, drawing, or bending. Forming machines create the basic structure and dimension of the metal cans by making them more rigid and stable.


The fourth and final stage in producing metal cans is known as seaming. The lids are attached to the can bodies at this stage using seaming machines. The process involves double or single seaming, which make the cans more airtight and leak-proof.

At Aladdin Factory, we use seaming machines that seam up to 200 cans per minute. We also have quality control machines that check the tightness and alignment of the seams. Our seaming process meets all the required safety, strength, and hygiene standards.
