About Induction Flood

 

Like the laws of attraction, the laws of Induction cap sealing do not change over time. The rules on how Induction cap sealing works today are no different than they were 10 years ago. In this article, we are going to separate the facts from unreasonable assumptions about inductive devices so that everyone can understand the fundamentals of these devices and provide suggestions to help you choose the most suitable device to use. To help you.

Since the emergence of this technology in the mid-60s of the twentieth century, there has been a shadow of ambiguity over this phenomenon. Most of this confusion and inaccurate information is generated by manufacturers and sellers of induction seals, as well as manufacturers of lids and dish washer.

During the last 20 years, significant changes have been made in electronic equipment as well as Induction cap sealing heads. Power Supplies

And the sealing heads have become much smaller and more efficient. Work that previously required a power of 5 kW is now much less feasible. (Of course, the classification of devices based on other electrical power (kW) has become obsolete, which will be explained in more detail later.)

Well let's talk about the basics of Induction cap sealing. What is induction sealing and what can it do for you? Induction cap sealing is a non-contact heating process that seals the (non-metallic) containers with a cover inside a thermal sealing gasket so that it is impervious to gases and liquids. These gaskets can include a cardboard or foam backing, a paraffin layer, a thin aluminum layer, and a heat-sensitive polymer layer that is compatible with the container material.

 

 

The support can be made of EPE with different volume mass, cardboard, etc. Depending on the material of the container contents and the manufacturer's requirement. This type of gasket, which remains in the cap, is known as a two piece gasket. Two-piece gaskets are usually used when the manufacturer wishes to use a foam layer or cardboard residue inside the cap as a second gasket to seal after the aluminum layer has been abraded by the consumer and if all contents of the container are not consumed at one time, To use. Another type of Induction cap sealing gasket is a one-piece gasket, which is similar to two-piece gaskets except that the second gasket is no longer as it is named. These gaskets can have the desired print, such as the manufacturer's logo or registered trademark, or a general message such as "sealed for freshness". They can be very tightly attached to the opening of the container so that the consumer has to tear it with a winning object or be detachable so that it can be easily separated from the container. Because of the different types of induction sealing gaskets, it is advisable to consult a specialist before selecting one.

What are the main components of induction seals? A standard induction coupler consists of two main parts: the power supply and the induction head.

The power supply is a power generator capable of operating at medium to high frequencies required for the Induction cap sealing process. This power supply supplies the electricity needed to create the magnetic field by the induction head. The power supply for a particular application depends on the size of the washer used and the speed of the conveyor.

The induction head (Fig. 2) comprises a plastic housing and a coil that forms an induction coil.
