Why is Leak Detection Needed?
This video explains the critical role of Light Leak Detection systems in ensuring the integrity of aluminum cans. These systems identify tiny holes or cracks in the can body that could lead to significant issues later in the production and distribution process.
Small holes or cracks in a can body can occur due to:
- Metal Defects: Flaws in the raw material.
- Metal Forming Process: Stress or damage introduced during the manufacturing process, such as during the Bodymaker or necking stages.
These seemingly minor defects can become major problems after the cans are filled. A single leaking can, known as a "Leaker", can ruin an entire pallet. When a can leaks, its contents—especially if corrosive—can damage the exterior of other cans on the pallet. While the interior of a can is coated to protect it from corrosive liquids, the exterior is not, making any contact with leaking contents a serious issue.
How Light Leak Detection Works
A Light Leak Detection System uses light to identify tiny holes or cracks in the can body. This highly sensitive system ensures that defective cans are detected in-line and removed immediately using compressed air and a valve.
Once defective cans are rejected, operators are notified to investigate and resolve the root cause of the problem,
