The working of machine begins with operator setting the basic functional parameters of machine. These include adjusting the height of induction heat sealing station, fixing the speed of conveyor belt and the level of temperature caused by an electromagnetic field.

Step 2

Now, when the basic parameters are fixed, machine is ready to start the process. When capped bottles start mobilization towards the induction heat sealing station, the sensor detects the presence of bottles and send message to machine.

Step 3

It is suitable for small batch packaging, laboratories or home based businesses and shops etc.

On The Basis of Function

Induction Heat Cap Sealing Machine

Allpack Induction Heat Sealing Machine

As manifested by the name, this machine is created to seal the bottles having plastic or metal caps over them. When capped bottles with attached aluminum foils are passed by the tunnel, heat is generated by the electromagnetic energy via induction coils towards bottles, where the aluminum foils of under caps get attached to the bottles' necks. Similarly, these bottles are discharged by conveyor and the process continues. Products such as liquids or chemicals which have high risk of getting affected by temperature or get leaked due to external pressure, are packed in capped bottles for which this machine is ideally perfect.

CaplessInduction Heat Sealing Machine

This innovative machine is most reliable in a way that it can be used for bottles with no caps over them. Its unique structure with inclusion of pressure belts for holding seals over caps is designed to facilitate the secure and undamaged sealing of bottles. During the process, bottles are transferred through conveyor. After reaching to sealing station, series of induction coils while taking aluminum foil adopt downward movement and apply the foils over bottles which swiftly get stuck to the bottles' necks. The machine is desirable for solid food, medicines and cosmetics.

8.Highlight The Main Differences Between Induction Heat Sealing Machine And Other Types Of Sealing Machines?

Along with induction heat sealing machine, there are other machines which perform the same function of sealing, however, they are different from one another. These differences can be understood by the table below:

No	Factors	Induction Heat Sealing Machine	Conduction Sealing Machine	Heat Sealing Machine
1	Definition	Induction heat sealing machine is designed to seal capped and capless bottles via electromagnetic heat energy	Conduction sealing machine is employed to seal the capless bottles through heated plate	Heat sealing machine is used for sealing plastic bags, pouches and films through hot bar sealing or impulse dealing
2	Sealing Method	Non-contact	Contact based	Contact based
3	Heat Source	Electromagnetic energy generates heat through induction coil	Electric power produces heat to hard metal plate	Heat produced by machine is spread through metal bars
4	Speed	Swift in producing heat	Slow in producing heat due to time taken by plate for warmth	It is fast in spreading heat and thus perform sealing quickly
5	Material Used	Aluminum linear	Aluminum linear	Hard to soft plastic film

9.Which Type Of Induction Wads Can Be Processed By Induction Heat Sealing Machine?

Picture Courtesy: Kaufmancontainer.com

There are mainly two types of induction wads which are used in bottles, jars or containers for sealing purposes. These are described below in detail:

One Piece Induction Wad

One piece induction wad is composed of foaming material, aluminum foil and a sealing material upward down the bottle cap. This type of induction wads are meant for sealing only once which means when the cap will be removed from bottle its purpose of protecting products will be ended. Therefore, goods like food products, cosmetics and beverages are often found with caps having one piece liners.

Two Piece Induction Wad

On the other hand, two piece induction wads are more durable in a way that they can be used for resealing. For instance, bottles with two piece induction wad if opened for consumption, the one piece will be removed while the other remains on the cap for resealing. Hence, products which are sterile and needs extra protection till the end of existence like chemicals, medicines and spirit are induction sealed with two piece induction wads.
