Some of the defects that can be identified using this inspection method include:

Incomplete Seals: Thermal inspection can detect areas where the seal is not properly formed or lacks sufficient adhesion, leading to potential leakage or compromised product integrity.
Seal Contamination: The system can identify instances where foreign particles or contaminants are present on the seal surface, which can pose a risk of product contamination.
Improper Adhesion: Thermal inspection can detect areas where the seal has not adhered properly to the container or bottle, indicating a potential weakness in the seal’s strength.
Seal Misalignment: The system can identify situations where the seal is not properly aligned or positioned, resulting in an uneven or imperfect seal.
Seal Cracks or Breaks: Thermal inspection can detect cracks or breaks in the seal that may compromise its integrity and allow for the entry of air or contaminants.
Seal Irregularities: The system can identify irregularities in the seal’s shape or width, ensuring consistency and uniformity.
Inconsistent Cap Torque: When a cap is inadequately tightened on a bottle, there is insufficient pressure to form a quality seal. This appears as areas of lower and higher temperatures around the perimeter of the seal, which can be identified by the inspection system.
Missing Cap or Seal Foil: If a cap is missing completely, or the seal foil is missing, the thermal camera can easily detect these irregularities.
Incorrectly Configured Sealing Process: If the sealing equipment is not operating in the optimal sealing range, this can be identified by higher or lower than normal temperatures in the seal. The inspection system can reliably identify any changes to the seal temperature that may lead to missing or incomplete seals (under-power faults), or seal/cap burning (over-power faults).

Yes, the thermal inspection system can be integrated into existing production lines. It is designed to seamlessly integrate with the production process, allowing for efficient and automated quality control.

The thermal inspection system can be synchronized with other equipment and machinery in the production line, such as conveyors, sensors, or control systems. It can communicate with the plant’s PLC (Programmable Logic Controller) or other control devices to transfer status messages, PASS/FAIL results, or trigger actions based on inspection outcomes.

The inspection speed of the system can vary depending on factors such as the specific model, configuration, and the complexity of the inspection requirements. Typically, thermal inspection systems are designed to operate at high speeds to keep up with the production line’s pace.

The exact inspection speed can be influenced by factors such as the size and design of the product, the conveyor speed, and the complexity of the inspection criteria. As part of the pre-engineering engagement, MoviTHERM works through all the technical aspects to arrive at an expected throughput number that is consistent with the physical realities and constraints.

Using thermal inspection offers several benefits compared to other inspection methods. Here are some advantages:

Non-contact Inspection: Thermal inspection is a non-contact method, meaning it does not require physical contact with the bottle caps. This eliminates the risk of damage or alteration to the caps during the inspection process.
Real-time Detection: Thermal inspection provides real-time feedback on the seal integrity of bottle caps. Defects such as incomplete seals or seal contamination can be immediately identified, allowing for prompt corrective actions.
High Accuracy: Thermal inspection systems use advanced infrared cameras and algorithms to accurately detect temperature variations. This enables precise identification of seal defects, ensuring reliable inspection results.
Speed and Efficiency: Thermal inspection can be conducted at high speeds, keeping up with the pace of production lines. It enables efficient and continuous inspection without slowing down the manufacturing process.
Comprehensive Coverage: Thermal inspection can assess the entire seal area of bottle caps in a single image, providing a comprehensive analysis. It can detect defects across the entire circumference of the cap, ensuring thorough inspection and minimizing the chances of undetected issues.
Automation and Integration: Thermal inspection systems can be seamlessly integrated into existing production lines, automating the inspection process. This reduces reliance on manual labor and enhances overall efficiency.

By leveraging these benefits, thermal inspection provides manufacturers with a reliable and efficient method to ensure seal integrity, minimize defects, and maintain high-quality standards.
