The Process of Can Manufacturing

A can is a small container that is used for storage and distribution of items. In most of the times, the cans need to have removable covers for retrieving the products while others may be enclosed in such a way that they have to be cut open. Cans are often used for industrial purposes such as storage of product meant for sale or holding beverages, oil, chemical among other several uses. The process of manufacturing cans, aided by can making machine, is not a complex one but involves processes such as seaming and fabrication.

There are numerous steps involved in tin making and must follow each other strategically to achieve a perfect can. They include the curling of the top, body making, slitting, seaming, flanging among others. The primary material is the tin plate, and the slitting process cuts it into precise size and shapes. The combination of these steps results in an end product which is the desired can.

Slitting or Shearing

The first in the can making process is cutting the blanks in various sizes. The packaging can are often made in different sizes and shapes to fit the requirements of the customers. The tin can-making machines, therefore, contains structures that allow altering of shapes and sizes of the cans as demanded. The common types of tin cans produced in large quantities include mint tin and soup tin. The walls of the tins are stiffened with bulges to avoid dents. Cans are usually made from tin aluminum or can be coated with tin depending on the content packed in them. Once the blanks are cut in right sizes, process of can body making begins.

Can Body Making

Once you have the right sizes for your machine, the next step is can body making. Depending on the kind can making machine production line you are using, the entire can body making should fully automated. Where the blanks are folded to for the actual shape of the tin.


The process of seaming involves the integration of the can body with the bottom and top lid. Several steps such as flanging are part of this process. One end of the can which is undergoing curling is flanged with the body of the can, and then they are joined. The can making machine that conducts this process has various components which include a closing station, seaming chuck, base slate and the operation rolls. However, seaming process depends on the can maker machine that you are using.


Fabrication process has a number of stages that are involved. These include the formation of the cylindrical form from the plate and then soldering of the seams. It then follows the integration of the can body with the bottom end. What comes next is the attachment of the labels and then their printing to include the details of the content inside. After this, the blank can is filled with the desired content. For preservation purposes, sterilization or retorting is conducted before the final step is carried out which is the joining of the body with the top lid.
