Tear-off is a common defect for can makers. Can makers want to know the true tear-off causes in order to take prevent actions to avoid the defect occurrence. However, many factors can result in the tear-off during can deep drawing, and the confirmation of cause is challenging due to the fact of very thin can wall (~100µm) and seriation fracture cross section.
Secat can identify the cause of tear-off. Below is an example.
The defects in both casting and rolling process can result in a pinhole defect on the cans. Secat can identify the cause of the pinhole. Below is an example.
