Brief Introduction
A can seamer machine is used to hermetically seal a lid to a can body during the packaging
process using a double, or sometimes triple, seam. The lid is usually made from tin-plated
steel. Meanwhile, the can's body can be made of paper (like whiskey cans), tin, aluminum,
PET, plastic, or glass. The formed seam is usually leak-proof. However, this still depends on
the type of products being packaged.
Moreover, you can automate can seamers to streamline the packaging process to improve
production efficiency and save on labor costs. Apart from these, you can also enjoy other
benefits of integrating an automated packaging machine in your production line.
Feature
#1 Seamer Head (Chuck)
The machine's seaming chuck holds the can firmly together with the seamer turntable on
the other side during the process of double seaming. It also protects the can from the
pressure of the first and second seaming roller operations. The chuck's dimensions will
depend on that of the can's diameter being sealed. Thus, different chucks are needed for
different can diameters.
#2 Seamer Turntable (Base Plate)
Also known as the compression plate, the seamer turntable which is a disc spins freely and
gives support to the can body during the sealing process. It centers the can body in the
correct position . Also, the base plate's shape will depend on the can's shape, allowing
the can to be inserted into it correctly
#3 Seaming Rollers
Can sealing machines consist of two seaming rollers having concave profiles that help in creating double
seams. Depending on the speed of the machine.
The first seaming roller's profile and its position with respect to the seaming head are critical in producing a
reliable double seam. The majority of the double seaming problems encountered arise from the incorrect
setup of the first seaming roller operation. On the other hand, the second seaming roller's groove will have
a shape similar to that of the produced final double seam.
#4 Sealing Chamber & Vacuum Room
Can sealing machines, such as nitrogen filling vacuum sealing machines, perform the sealing process in sealed
chambers especially when removing the oxygen from the containers prior to the sealing process. The removal
of oxygen takes place inside a vacuum room under vacuum pressure. This maintains the integrity of the
product inside.
#6 Feeder Caps
All automatic can sealing machines have cap feeders that take a lid from a pile of closures and transport the
lid to the sealing station before the sealing process.
#7 Transport
Every can sealer machine has its own way of transmitting the filled containers into the machine. But, the most
common ones are power conveyors that continuously move the containers from one station to another
during the sealing process
