Tin can sealing machines hermetically seal a lid to a can body during packaging. Most of the formed seam is leak-proof. A tin can sealer can either have one or more seaming heads. Machines with four, six, or twelve heads are popular as the heads increase the machine's speed for production lines. A tin-sealing machine is widely used in the beverage, food, pharmaceutical, chemical, and cosmetics industries.
An automatic tin can sealing machine is a great way to streamline the packaging process, as most processes are done automatically. Things that the operator needs to do is to supply lids in bulk to the machine. Therefore, such tin can sealer highly improves production efficiency and saves on labor costs. Automatic tin can capping machines are well suited for businesses requiring high production demands. Manual tin can sealing machines typically seal one container at a time, and the operator needs to initiate the can seaming process through a finger-switch or foot-switch for each sealing cycle. These machines are great for small productions, and most home tin can sealing machines are manual tin can sealers.
Generally, a tin sealer has a head, a turntable, seaming rollers, sealing chambers, an ejector, and feeder caps. The seaming head of a tin can sealing machine is used to hold the can firmly with the machine's turntable during double seaming. It also protects the tin can from the pressure of seaming roller operations. Different cans need for different chucks in diameter. The turntable for food can sealer machines is a spring-loaded disc. It spins freely and supports the can body during the sealing process. The shape of the turntable is based on the can's shape. There are two seaming rollers in the tin can seamer machine. These rollers have concave profiles and help in creating double seams. A tin-sealing machine can have one or more sets of seaming rollers according to the speed of the machine.
