Product type
Induction sealing machines are specialized devices used to seal containers with a non-contact method that utilizes electromagnetic induction. These machines typically consist of a power supply, induction coil, and a conveyor system to transport products through the sealing area. The process involves creating heat through electromagnetic fields, which melts a foil liner on the container's cap, forming a hermetic seal that preserves product freshness and prevents leakage.
| Power supply | Single-phase or three-phase |
| Sealing speed | Up to 300 containers per minute |
| Container types | Plastic, glass, and metal |
| Seal diameter range | 20 mm to 120 mm |
| Control system | Digital or analog |
| Cooling system | Air-cooled or water-cooled |
When selecting an induction sealing machine, consider the type of containers you will be sealing, as well as the desired sealing speed and production volume. It's important to specify the diameter of the seals required, along with any specific material compatibility. Additionally, inquire about the machine's control features and whether it meets industry standards for safety and efficiency. Quantities may also affect pricing and lead times, so be prepared to discuss your production needs.
