Canned food manufacturers need can sealing/seaming machines to ensure the integrity of the seams of their packaged goods. This avoids product contamination and spillage. Some can sealers even come with vacuum and nitrogen gas flushing devices to extend the product’s shelf life. Vacuum can sealers work by removing the oxygen from the containers before the sealing process.
Below is a list of the parts you need to have to build a small can sealing machine. For the sake of this guide, we will use an Ives-Way can sealer, a small can sealer you can easily assemble, as our example. You can assemble most can sealers in the same way but we suggest that you follow the instruction manual that came with the can sealer kit you bought.
Crank & Screw
Seaming roller washer
1st and 2nd seam rollers
2 Seaming roller springs
2 Seaming roller screws
2 3-hole nuts (left & right)
2 Adjusting thumb screws
2 3⁄16-inch Spacers
Below are the additional components you will need depending on the size of the cans you are going to seam.
For Tall 1-Pound Cans (301×408)
For these cans, you will need a #301 chuck.
For Flat ½-Pound Cans (307×200.25)
For half-pound cans, you will need a #307 chuck and an additional 5⁄16-inch spacer.
Before you start assembling your can sealer, determine the size of the cans you will be seaming first. Now, let us go into the assembly steps.

Building your own can sealing machine is a fun experience. It helps you learn the basics and familiarize yourself with how these machines work before you buy a pre-built one in case your production demand increases. We hope that you will have fun in assembling your very own can sealer through this guide. You can also find a high-quality can sealers and can filling machines here in Levapack.
