Basics of Induction Sealing Performance


Like the laws of attraction, the laws of inductive coupling do not change over time. The rules on how Induction cap sealing works today are no different than they were five years ago.

This article separates the facts from the irrational assumptions about inductive coupling devices so that everyone can understand the basics of their performance, as well as suggestions to help you choose the most suitable device for your intended use. .

Ever since the advent of Induction cap sealing technology in the mid-twentieth century, there has been a shadow of doubt about 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.

Over the past 20 years, dramatic changes have been made in electronic equipment as well as induction sealing heads. Power supplies and sealing heads have become much smaller and more efficient. Work that previously required a power of about 1 kW is now much less feasible. (However, the classification of devices based on electrical power (kW) has become obsolete, which will be explained in more detail below.)

Let's talk about the basics of Induction cap sealing behkar electronic. 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 cap inside a thermal sealing gasket so that it is impervious to gases and liquids. These washers 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 material of the container. The support can be made of EPE with different volumetric mass, PE, Teflon, wood, etc. Depending on the contents of the container and the manufacturer's requirements. This type of gasket, which rests inside the cap, is known as the two-piece gasket.

Two-piece gaskets are usually used when the manufacturer wishes to use a foam layer or residual cardboard inside the cap as a second gasket to seal after the aluminum layer has been removed by the consumer and if the contents of the container are not consumed at one time, use. Another type of Induction cap sealing gasket is the one-piece gasket, which is similar to the two-gasket gaskets, except that the second gasket, as the name implies, is no longer available. These washers can have a custom print, such as a manufacturer's registered logo or trademark, or a public message such as "sealed to keep fresh." They can be very tightly attached to the opening of the container so that the consumer will have to tear it with a winning object or be detachable so that it can be easily detached from the container. Because of the different types of induction sealing gaskets, it is advisable to consult with experts before selecting one.

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

ـ The power supply is a power generator capable of operating at medium to high frequencies required for the induction sealing process. This power supply supplies the electricity needed to create the magnetic field by the induction head.
