Making a tin can involves several steps that distinctively correlate with each other. These manufacturing processes include top curling, can body making, shearing/slitting, beading, seaming, flanging and many more. The primary material used by can making machine is mainly the tin plate. A slitting or shearing machine cuts the plate precisely until the required blanks are obtained with the desired length and width. These lengths should be able to fabricate into a single body during the final process.
The slitting process can be automated or done manually. Before you embark on this process, you should ensure the slitting machine works effectively depending on the necessity. There are three types of slitting machines namely:
- Manual slitting machine
- Semi-automatic slitting machine
- Fully-automatic slitting machine
There is a machine that is responsible for the body. This machine is programmed fully to incorporate various manufacturing processes at the same instance. This can machine usually does many tasks and can produce many can bodies in a short time interval. The steps incorporated during tin body production include pre-curling, making groove, notching, locking, and forming. All these processes have been integrated into one chain and operate in a synchronized manner.
Body making process should be done automatically to minimize the production cost. When you incorporate such mechanisms in your production line, you will be guaranteed to spent low expense regarding power consumption, space, maintenance cost among other issues. A tin body machine can also be adjusted to permit various sizes and shapes.
Top curling Machine
This is the can machine that is responsible for curling the top of the can. This will ensure the top part of the can have specific depression, and the can have the desired shape usually an excellent rim.
The beading machine is responsible for convex exterior and hollow interior area of a can. The can goes through a series of bulges and small depressions until the desired designed are obtained. The reason for beading in tin making process is to get a furnished can come with higher quality and stability.
This machine is mainly meant to reduce or lessen the diameter or width of the can at the top. This necking process will ensure a narrow head is obtained that consequently makes the can look cool.
The bottom of the can is joined with the can’s body through the seaming process. This seaming machine can either do single or double seams depending on your preferences. However, the latter is usually preferred as it impeccably lasts longer and holds tightly.
The flanging machine is designed to make flanges on the top and bottom ends of the can. The edges are formed and flanges leveled at the two ends.
Making a lid comprises several easy steps. There is trimming, edge curling, and punching from the blanks. Machines that have incorporated cutting-edge technology usually do the lid making process. At the inception, the blanks are punched precisely until the ideal lid is obtained with the desired shape and design.
Finally, there is a bottom making machine that punches the blank slits when making the bottom sections. The punched part is then seamed, and the can is the channeled through the sealing process.
