The main causes of can breaks in the formation can be varied and can be divided into two categories: isolated causes and common causes in the process.
Isolated causes:
- Problems in a cup press.
- Problems in a cup press cavity.
- Problems in a body former.
Common causes in the process: - Problems in an aluminum coil.
- Problems in the coolant oil system (Coolant).
- Transport damage to the cup accumulator (See Figure 1 in the information provided).
- Problems in the cupper oil applied in the cupper lube.
- Other sources common to the system.
Root cause analysis is a useful tool to quickly identify the solution to these problems affecting production lines. By looking for failure patterns and analyzing the type of break initiation, it can be determined whether the problem is isolated or common to the process. This will help ensure the continuity of the production lines and, consequently, improve the quality of the final product.
