Description
The ZONESUN ZS-MD50 is an automatic foil-seal inspection machine designed for high-speed production lines. Operating at up to 200 bottles per minute, it uses non-contact infrared thermal imaging to evaluate the sealing quality of induction-sealed or heat-sealed bottle caps. The system accurately detects missing foil, weak sealing, overheating, skewed caps, loose caps, and other sealing defects without touching the product. With its wide cap-size compatibility, high pass rate, and precise imaging accuracy, it provides reliable, efficient, and real-time quality control for cosmetics, food, beverage, and chemical packaging lines.
Note: The system does not detect double caps or foreign objects at the seal.
IMPORTANT OPERATING REQUIREMENTS
- This machine uses infrared thermal imaging and must be installed immediately after an aluminum foil induction sealing machine.
- Each container must be inspected immediately after sealing while the foil seal is still warm. Once the sealing temperature has dropped, the machine cannot perform a reliable inspection.
- This inspection machine cannot be used as a standalone machine.
- Not suitable for containers with metal caps.
