Things to Know When Using a Can Sealer
Understanding the Sealing Process
A can is sealed by attaching the can lid to the can body and creating a double seam. The outer end of the can lid is known as the curl; the outer top part of the can body is known as the flange. The double seam is formed by interlocking the curl of the lid with the flange of the body.
In a series of automated processes, the can sealer compresses the curl and the flange and mechanically interlocks them. The can sealer also applies a sealing compound to fill out any remaining gaps and make the double seam airtight. Your involvement in the sealing process depends on the type of machine that you have:
- Semi-automatic can sealer: You manually put the can on the sealing chamber.
- Automatic can sealer: You will have minimal involvement in the sealing process. The can enters the seamer through a conveyor.
It would also help you learn to use a can sealer if you knew more about the different designs and operations of can seamer machines.
Evaluating a Double Seam
Can sealing is all about making a reliable double seam. The integrity of the double seal formed in your cans is crucial. This will ensure that there will be no leaks and your product inside the can will not be contaminated. Part of learning how to use a can sealer is learning how to evaluate the double seam produced by your machine after it is fully set up.
The shape and specifications of the double seam are determined by the components of your can sealer. This includes the position of the rollers, the height of the turntable, and the pressure exerted on the can. You should set up a system to inspect the double seams at sufficient intervals in the operation. If your machine seals hundreds of cans every minute, and you fail to detect a defective seam right away, that will result in thousands of cans that are not sealed right.
Using a seam micrometer, measure crucial dimensions of a double seam created by your can sealer. The crucial dimensions that you need to look out for are the lid hook length, body hook length, width, tightness, and thickness. Also, observe for any wrinkles. You can work with your manufacturer representatives to learn more about the proper specifications and technical data for your double seam.
Setting Up Your Can Sealer
When you order a can sealer, you never set the machine up yourself. Representatives from the can sealer manufacturer will provide technical support. Going into the technical details may be unnecessary, but an adequate understanding of these procedures will help you use your can sealer.
Engineers with years of experience assemble the can sealer by hand, putting the right parts in their proper places. Once the can sealer is assembled, the representative will carefully inspect the machine. They will make sure of the following:
- all components run smoothly,
- electrical parts are properly connected,
- toolings are correctly installed,
- wirings are not loose and look pleasing to the eyes,
- motors run without overheating and creating too much noise.
After the inspection, the engineers will run trial tests with your sample cans to guarantee that the operation will produce the desired final product.
During this process, work with the representative from your can sealer manufacturer. Let them explain to you the different components of the can sealing machine. Don’t hesitate to ask them questions. The insights that you gain from these representatives during the assembly and inspection will enhance your ability to use your can sealer.
If you partner with LEVA Packaging Equipment (LPE), one of the best can manufacturers in China, patient engineers are always ready to assist you with any technical concerns.
Operating Your Can Sealer
How to Operate a Semi-Automatic Can Sealer
Manual and semi-automatic can sealers are basically operated the same way. The only difference is that manual can sealers do not use any power source before you can use them. Meanwhile, semi-automatic will need electricity before they can operate. Below is a sample step-by-step guide on how to use a semi-automatic can seamer in sealing dry goods.
- Adjust the machine’s components to match the size of your can so that it can seal it properly. You can raise the can pedestal up or down using an adjustment dial or a raising arm depending on the machine you are using.
- Fill your containers first leaving a ¼ inch space from the lip of each can. Check your machine’s instructions if it can handle the type of product you are sealing. Because some can sealers are only meant for dry goods and not for wet foods.
- To prevent the remaining oxygen inside the can from spoiling the product, you can put an absorbing packet on top of the dry goods first before sealing.
- Place the lid on the filled can and make sure that it faces the right direction (the ridges must be facing upwards).
- Place the capped can on the machine’s can pedestal and push the lower level. This raises the can pedestal.
- Push down the machine’s lever and then leftwards to lock it.
- To start the sealing process, push the sealing handle forward.
- Keep increasing the pressure on the machine’s sealing arm for about 5 seconds. Now, pull the sealing handle towards you and repeat this process. The sealing process is now completed.
How to Operate a Fully Automatic Can Sealer
Fully automatic can seaming machines are usually integrated in a production line for a continuous packaging process. So, the operator only needs to start the machine via its control panel and provide bulk quantities of lids into it then let the machine do the rest.
Taking Care of Your Can Sealer Regularly
Taking care of your can sealer regularly will help sustain the proper functioning of the machine and the quality of your products. Every now and then clean the machine from debris, stains, and hand prints. Use anti-rust oil to polish the can sealer. This will prolong its lifetime.
Conclusion
Learning how to use a can sealer will help you make your can sealing operations more efficient. You will achieve significant business growth with higher profits and reduced production costs. This growth will be experienced in the long-term because you will be able to prevent breakdowns and interruptions in your operation. The key is to learn what you can and to develop a trusting relationship with your manufacturer representatives.
