Conduction sealing needs the hard metal plate to make proper contact along with the container being sealed. Conduction sealing systems delay the production time because of the requisite system warm-up time. They also have complex temperature sensors and heaters.

Unlike conduction sealing systems, the Induction Sealing systems need very little power resources that offer an instant startup time, and also have the sealing head that can conform to “out of specification” containers while sealing.

Utilizing the accurate conduction sealer, one can easily seal the simple foil structure to glass gives no tolerance or compressibility for permitting any irregularity in the glass surface finish. With help of Induction Sealer, the contact face can be of a compressible material, ensuring a perfect bond each time.

Pros of conduction sealing vs. induction sealing

  • The sealing material of conduction heating per unit is normally less than the induction sealing material.
  • In conduction sealing, the products can be sealed without a cap or a lid whereas, in induction sealing machines, the cap-less sealing is possible.
  • You have the option of inspecting each and every seal visually as there is no cap or lid covering the seal during the sealing process. Induction machines can be easily powered on and ready for production nearly instantly.
  • Low-cost plastic seals are used in the conduction sealing. Proven, reliable Lapel technology goes into every piece of equipment in the induction sealing.

Knowing the disadvantages of heat sealing

  • Products are sealed without the lid or cap in place but in induction heating, you will get the product properly sealed with a lid.
  • Product handling is a bit tough and complicated when automated as the products require being transported, without spillage, in the sealing machine using cups or turrets in open containers. The process of induction sealing is not so complicated.
  • Machinery is more dedicated to some particular sizes of containers, given the difficulty of transporting open containers.
  • Versatility of heat sealing or conduction sealing machinery is limited and it needs particular change parts if a different size or shape container is to be sealed using the same machine. Induction machines are extremely versatile and can handle many different shapes and sizes of containers.
  • There has been a physical source of heat, which comes into contact with the container to melt the seal in place. Induction machines do not require touching or handling the product.
  • The conduction heating machine is rotary in nature and it also enhances the cost and size of the equipment. In the induction sealing, the size and cost of equipment does not increase very often.
  • The conduction heat machines have lots of services and set up issues compared to the induction sealing procedure where no physical contact is there.
