Engineering Challenges

Technical challenges addressed
Sealing glass jars at speeds above 1,200 jars/hour requires:

  • Maintaining thermal stability in the induction head
  • Precise foil placement at speed
  • Consistent sealing pressure across rigid glass finishes
  • Safe and accurate indexing of jars

Risks of improper sealing

  • Incomplete hermetic seals
  • Foil misalignment
  • Thermal drift causing weak seals
  • Higher reject rates and downtime

This machine addresses all these challenges through smart design and engineering.

Frequently Asked Questions (FAQ)

What production speed can a single-head induction sealer achieve?

1,200–1,400 jars per hour, depending on jar size and foil specifications.

Why is air cooling necessary in induction sealing?

Air cooling maintains thermal stability in the induction head, preventing heat drift and ensuring consistent seal quality.

Can induction sealers handle glass containers?

Yes. With precise positioning and pressure control, induction sealing is highly effective for glass jars.

Can date and lot codes be printed on the foil seal?

Yes. An integrated inkjet system applies date codes, lot numbers, barcodes, and product information directly onto the foil.

What causes inconsistent induction seals?

Common issues include improper foil placement, insufficient pressure, overheating, or poor container alignment.
