The size of the chuck will be determined by the radius windage of the can being sealed. As a result, separate chucks are required for various can radius windage.


Rotary Sealing Machines

The seamer turntable, also known as the compression plate or base plate, is a spring-loaded disc that rotates independently and supports the can’s body during the sealing process.
