Types of Induction Sealing Wads

What is Induction sealing wads

Induction sealing wads are designed to seal a gas or liquid under pressure, with a gasket surrounding an opening. The seal is created in a rolling manner, meaning the plunger head moves, compressing the gasket and filling the chamber. Induction sealing wads can be used in many industries such as medical, food processing, and packaging.

How does Induction sealing wads work

The induction sealing wads are also called heat seal liners as they involve the method through which thermoplastic elements produce heat. The material can be made up of aluminium, plastic, foam, etc. The Induction cap sealing machine then creates an airtight seal on top of glass or plastic containers.

The process is done after the filling and capping are done. The electronically heated process ensures that there is no product spillage. It also prevents the chances of product tampering as the induction seal can’t be used again once punctured.

Types of Sealing wads

For an induction sealing to be effective, it should have a gasket that is not too thin and a seal that will be airtight when the gas or liquid fills it to its maximum capacity. This can also affect the ability of a unit to seal properly. The weight of the gas or liquid being sealed should not exceed the maximum compression force that can be made by the plunger head due to being sealed by an induction sealing wad.

There are many different types of induction sealing wads. These wads normally come in a solid, plastic, or rubber material. The material should be durable enough to withstand the pressure from the sealing process.

Some sealing wads are made with various features to help achieve the proper compression seal. These features include:Two different types of wads can be used in the sealing process. They are either seat or cap-type wads.

The seat or cap type wad: 

They are designed to cover a smaller area of the opening, much like a seat cover on your car's steering wheel. The hole is normally much smaller than what it needs to be for two reasons. One is to reduce the force needed to fill the chamber, and the second is to protect against leakage for when you need it most; when filling liquid or gasses with your piston head nozzle.

 Off-the-shelf Wad:

The other type of wad is the "off-the-shelf" wad. It can be installed on just about any machine that needs to seal an opening. These wads are made to plug the hole completely, so no gas or liquid can escape if the air is trapped inside of it. The off-the-shelf wad is normally made with thicker material than seat or cap types due to its increased ability to support pressure under pressure.

The most common seal used in industry today is called a split ring seal. This type of seal consists of a hard metal ring and rubber gaskets that clamp onto one another; creating a seal around the opening.

Conclusion

 An induction sealing wad protects the product from spillage, contamination and also makes the container pilfer-proof. With the enchantment of holography incorporated, the induction wads are created tamper-proof and are more safe and significant than ever before. Steril Medipac induction sealing wads are of great quality and are made with utmost precision. Also multi color printing of induction sealing liners and Induction sealing wads for glass bottles is also possible.
