Why do we inspect cap seals ?
Induction cap sealing is widely used for packaging in many industries. The quality control of bottle cap sealing is a very important step during bottled product's processing line to assure that the products are safe to transport and store.
This applies to numerous products, including pharmaceutical, food, beverages, cosmetics, detergents, disinfectants, and pesticides among other examples. The assurance of the seal effectiveness is particularly relevant when products are potentially harmful to humans or the environment.
Partial, weak, or warped seals will cause leakage which corrupts product quality and, in some cases like pesticide bottles, threatens people's health.
During the aluminum induction seal process, lots of factors will influence the seal integrity.
- insufficient power from the induction sealer
- conveyor too fast or too slow
- improper coil height, insufficient application torque
- induction liner incompatible with the bottle
- bottle neck was flamed or chemically treated.
- other causes
Our solutions
Our system adopts a high-grade thermal imaging camera to capture the heat profile on the cap and transmit to the host machine. The Ai-powered vision inspection software analyzes the images, detect the defective products and then command the rejection unit to kick off every unqualified product automatically to the recycle bin, which are later collected by workers to re-pack up.
The method is non-invasive, automated, and can be integrated with common conveyor belts currently used in industrial plants.

Is it worthy it to implement a Vision Inspection System?
Inspection of product packaging is critical to ensure products are safely packaged for end consumers. Using a vision system you can achieve 24/7 operation and track and record every product inspected. With a Vision Inspection System you can achieve the following:
• Minimize quality defects
• Protect the customer and consumer
• Protect your company brand and reputation
• Offer a return on investment (ROI)
• Support adherence to industry best practice guidelines and industry standards
• Mitigate the risk and impact of product recalls and returns
Investment of a vision inspection system will pay off over time, by eliminating mislabeled products, label mix-ups and the associated costs resulting from mistakes, you can avoid costs from product recalls, fines and production rework.
This machine can be installed flexibly to be integrated with customer production line, and the user-friendly software interface makes it easy to operate. After a routine training, the workers will be fully capable to use this powerful inspection machine.
