At Relco, innovation is driven by real production challenges—not unnecessary complexity. Our engineering team has developed a practical induction sealing solution that allows a single machine to seal two different bottle heights with the same diameter, using one sealing head.
This solution was created in response to a common bottling problem faced by manufacturers across food, pharmaceutical, chemical, and personal care industries.
The Challenge: Sealing Bottles of Different Heights Efficiently
In many production environments, bottles share the same neck finish and diameter but vary in height. Traditionally, this required:
- Separate induction sealing machines
- Multiple sealing heads
- Lengthy and error-prone changeovers
These approaches increase capital costs, downtime, and operational complexity—especially for manufacturers running multiple SKUs or short production batches.
The Relco Solution: Simple, Engineered, and Production-Ready
Relco engineers designed a custom precision base piece that is placed beneath the shorter bottle. This base raises the bottle to the correct height, ensuring perfect alignment with the induction sealing head.
Because the induction head position remains unchanged, the machine can seal both bottle sizes reliably and consistently—without mechanical adjustments or additional equipment.
Does This Affect Seal Quality?
No. Seal integrity and consistency are fully maintained. Proper alignment ensures:
- Even heat transfer
- Reliable liner activation
- Secure, hermetic seals
The sealing performance matches that of a dedicated single-height setup, making this solution suitable for industrial production environments.
Key Benefits for Bottling Operations
- Reduced equipment investment – one machine instead of multiple
- Minimal changeover time – no sealing head swaps
- Greater line flexibility – ideal for multi-format production
- Lower maintenance complexity – fewer components to manage
These benefits directly support higher uptime and improved overall equipment effectiveness (OEE).
Designed by Relco Engineers, Built for Real Production Lines
This solution reflects Relco’s focus on engineering-led, customer-driven innovation. Rather than introducing complex automation, the team delivered a robust mechanical solution that integrates seamlessly into existing induction sealing systems.
It is compatible with bottles of varying heights that share the same diameter and induction-compatible liners.

The Takeaway
Relco’s induction sealing innovation proves that efficiency doesn’t require complexity. By using a custom-designed base piece, manufacturers can seal two bottle heights with one induction sealing machine, reducing costs, downtime, and operational friction—without compromising seal quality.
FAQ: One Induction Sealing Machine for Multiple Bottle Sizes
Q1: Can one induction sealing machine seal bottles of different heights?
A: Yes. Relco’s solution allows a single induction sealing machine to seal two different bottle heights with the same diameter using one sealing head. This eliminates the need for multiple machines or complex changeovers.
Q2: How does Relco’s solution work?
A: The key is a custom precision base piece that fits under the shorter bottle. This base raises the bottle to the correct height, aligning it perfectly with the induction sealing head, ensuring a consistent, secure seal for both bottle sizes.
Q3: Does this affect the quality of the seal?
A: No. Seal quality remains consistent and reliable because proper alignment with the induction head is maintained. This ensures even heat distribution, proper liner activation, and hermetic seals suitable for industrial production.
Q4: What types of bottles are compatible with this solution?
A: It works for bottles that have:
- The same diameter
- Different heights
- Compatible induction sealing liners
Industries that benefit include food, beverage, pharmaceutical, chemical, and personal care manufacturing.
Q5: What operational benefits does this solution provide?
A: Manufacturers gain:
- Reduced equipment costs – fewer machines required
- Faster changeovers – no need to swap sealing heads
- Flexible production – one machine handles multiple SKUs
- Lower maintenance – simpler machine setup and operation
Q6: Can this solution be implemented on existing machines?
A: Yes. The custom base piece is designed to integrate with existing Relco induction sealing machines, allowing for a simple retrofit rather than full machine replacement.
Q7: Why trust Relco for induction sealing solutions?
A: Relco specializes in industrial sealing and packaging innovation, backed by:
- Proven engineering expertise
- Real-world production experience
- Customer-focused, practical solutions
- Long-term operational reliability
Every solution is designed with real manufacturing environments in mind, ensuring measurable efficiency and quality improvements.
Q8: What is the main takeaway?
A: Relco’s innovation demonstrates that efficiency doesn’t require complexity. By using a custom base piece, a single induction sealing machine can reliably seal two bottle heights with the same diameter, saving time, reducing costs, and maintaining high-quality seals.
