And to perform this kind of task, Induction sealing machine is used which is a modern equipment with latest technology installed inside for proper working.

So, to learn and explore more about how induction sealing machine is becoming popular across different industries and also how beneficial it is for your business line along with its working procedure you have to read this helpful guide.

1.What is induction sealing machine?

Induction Sealing Machine

Induction Sealing Machine

Induction sealing machines are a vital part of any business that needs to package products in containers. These machines create an airtight seal that keeps products fresh and prevents them from leaking.

An induction sealing machine is a device that uses induction sealing to hermetically seal the lids of containers. The machine works by using an electromagnetic field to generate heat, which melts the inner liner of the lid and creates a seal.

Induction sealing is a process in which an induction coil generates heat that melts a metal disk (called an inner seal) inside a closure. The molten metal forms a bond with the container and closure, creating a hermetic seal. These seal the contents of the container from outside contaminants and extend the shelf life of the product.

2.How induction sealing machine provide different benefits?

Induction sealing machine provides many benefits the industries. The benefits of an induction sealing machine are as follows:

Improved Shelf Life

Induction seals create an airtight barrier that protects contents from oxygen and moisture contamination. This can help to extend the shelf life of products.

Prevents Leakage

Induction seals can help to prevent leaks by creating a tight seal around the container opening. So, by doing this the product will not be leaked easily.

Tamper Evidence

Temper proof

Temper proof

Induction seals provide a visual tamper-evident seal that lets consumers know if a product has been opened before they purchase it.

Protects from Counterfeiting

Induction seals can be customized with logos or other security features to help protect against counterfeiting.

Remains Fresh for a Longer Period of Time

The induction seal products can remain fresh for a longer period of time. So, you can preserve them for long.  

3.What is the working procedure of induction sealing machine?

Working Process

Working Process

The working of the induction sealing machine is very simple. As we know that the machine uses the electromagnetic induction to seal the products.

There is an operator that is present there. So, the operator places the cap on the container. After that, the container is than placed on the conveyor belt of the induction sealing machine.

So, by doing this an electric field is created by the induction coil that is present in induction sealing machine. That helps in heating of the linear material that is present in the cap.

By providing the heat, the linear material melts. And after melting, the seal is then created by it between the container and the cap.

After doing the above procedure, the container is then cooled, and the seal is set. Now your product is ready to go.

This all the procedure of working of induction sealing machine.

4.What are the main parts of induction sealing machine?

The induction sealing machines are widely designed in different size and shapes. Therefore, every machine has different components.

But there are some components that are common in every machine. These components are considered the main parts of induction sealing machine.

Now in this section, you will come to know the important parts of induction sealing machine. These main parts are as follows:

The induction sealing machine has three main parts

  • The Power Supply
  • The Sealing Head
  • The Conveyor Blet

The explanation of these parts include:

The Power Supply

The very first main part of induction sealing machine is the power supply. The power supply provides the high frequency electromagnetic field that is required for induction sealing. It typically consists of a transformer, rectifier, capacitor, and coil.

This cable simply provides the electric power from the socket to the machine invertor. After that, the invertor then makes this power used for a machine that helps in sealing the products.

The important point to be noted is that you should always confirm the power rating of your machine. Power rating becomes important as by the reading you can come to know the suitability of your induction sealing machine.

The Sealing Head

Sealing head of induction sealing machine

Another main component of an induction sealing machine is the sealing head. The sealing head is where the container and cap are placed during the sealing process. It contains the primary and secondary coils that create the electromagnetic field.

The size of the sealing head is different according to the needs of the products to be sealed. It may be small or vast.

Also, the sealing coil that is present in the sealing head is considered to be a great metallic conductor.

Moreover, the coil has two main designs that are present in the market. These two are named flat coils and tunnel coils.

The flat coils are used for the inner sealing of products. The diameter of the products to be sealed is almost 20 to 120 millimeters.

On the other hand, tunnel coils are used for the caps like spouted ad flip-top. Also, this type of capping is not good for sealing solid products.

The Conveyor Belt

Conveyor Belt

The last crucial part of the induction sealing machine is the conveyor. The conveyor moves the containers through the sealing head. It is typically a belt conveyor with variable speed control.

You can adjust the speed of the conveyor belt according to your requirements. You just have to place the container on the conveyor belt. Then it will move automatically.

All these are essential parts of an induction sealing machine. Without these parts the machine is incomplete.

5.In which industries induction sealing machine is used?

The industries that use induction sealing machines are as follows:

Pharmaceutical Industries

Pharma line Credits

Pharma line Credits

Induction sealing machines are commonly used in pharmaceutical industries. The machine provides safety and protection to pharmaceutical products.

You can seal pharmaceutical drugs, syrups, capsules, tablets, ointments, and many other pharmaceutical products with the help of an induction sealing machine.

Chemical Industry

Chemical Industry

Induction sealing machines are widely used in chemical industries. The delivery of chemical products with full safety now becomes easy with induction sealing machines.
