A Guide to Can Making Line Equipment

Can making is a complex process that involves various steps, from forming the can body to decorating the finished product. Can making lines are designed to streamline this process and ensure that each can is produced efficiently and effectively. In this guide, we'll take a closer look at the different types of can making line equipment and the principles behind their functionality.
Can Body Forming Equipment
The first step in can making is creating the can body. This is done using specialized equipment that can form the metal into the desired shape. There are several types of can body forming equipment, including:
- Cupping press: This machine uses a punch and die to form the metal into a cup shape.
- Bodymaker: This machine uses a punch and die to draw the metal into a cylindrical shape.
- Draw and wall ironing (DWI) press: This machine first draws the metal into a cup shape, then uses a second punch and die to iron the walls of the cup to the desired thickness.
Can Body Welding Equipment
Once the can body is formed, it needs to be welded together. There are two main types of welding used in can making:
- Resistance welding: This involves passing an electric current through the metal to create a bond at the point of contact.
- High-frequency induction welding: This uses electromagnetic energy to create heat, which fuses the metal together.
Can Decoration Equipment
After the can body is formed and welded together, it's time to add decoration. There are several methods used to decorate cans, including:
- Printing: This involves printing the design onto the can using ink.
- Labeling: This involves applying labels to the can using adhesive.
- Embossing: This involves pressing the design into the metal so that it protrudes from the surface of the can.
- Debossing: This involves pressing the design into the metal so that it is recessed into the surface of the can.
Can End Making Equipment
Finally, the can end needs to be created and attached to the can body. There are several types of can end making equipment, including:
- Punch press: This machine uses a punch and die to cut the can end from a sheet of metal.
- Draw press: This machine uses a punch and die to draw the metal into the desired shape.
- Curler: This machine curls the edge of the can end so that it can be attached to the can body.
In conclusion, can making lines are complex systems that involve several types of equipment working together to create the finished product. By understanding the principles behind each piece of equipment, it's possible to optimize the can making process and ensure that each can is produced efficiently and effectively.
