What Happens Inside a Bodymaker? (Part 3) IPS CanSCHOOL

Introduction

This tutorial explains the final operation of the Bodymaker process, focusing on the formation of the dome at the bottom of a can. Understanding this step is crucial for those involved in can manufacturing, as it ensures the structural integrity and quality of the finished product.

Step 1: Understanding the Dome Forming Process

The dome formation is achieved through a series of precise movements by the machinery:

• Ram Action: The ram pushes the can through the outer Domer tooling. This initial action shapes the crown of the can.
• Tooling Contact: As the can moves forward, it contacts a second set of tooling designed to form the dome accurately.

Practical Tip

Ensure that the ram is calibrated correctly to maintain precision during the dome formation process. Any misalignment can lead to defects in the can's shape.

Step 2: Quality Control Imprint

The Domer tool is embedded with a distinctive imprint that plays a crucial role in quality assurance:

• Imprint Transfer: As the dome is formed, this imprint transfers onto the can, providing a reference for quality checks.
• Significance: This imprint helps in identifying any inconsistencies in the dome formation, ensuring that every can meets quality standards.

Common Pitfall

Neglecting to check the imprint can result in unrecognized defects, which might lead to product recalls or customer dissatisfaction.

Step 3: Removing the Can

After the dome is formed, the can must be removed efficiently:

• Ram Retraction: The ram retracts, allowing the can to be prepared for removal.
• Stripper Ring Use: A stripper ring assists in releasing the can from the punch.
• Compressed Air Application: Compressed air is used to ensure the can is fully detached before it proceeds to the next operation.

Real-World Application

Implementing an effective removal process minimizes downtime and enhances throughput in the production line.

Conclusion

In summary, the final shaping of the can's dome involves precise ram movements, quality control through imprints, and effective can removal techniques. Understanding these steps is vital for maintaining high standards in can manufacturing.
