WHY DOES TRIMMED CAN HEIGHT MATTER?

Understanding the can making process can be daunting. 

Collaborating with Kalvis Juanarajs, CEO of World of Can Making in a range named “Why Quality Matters”, Torus Measurement Systems are starting off by asking the question “Why care about Trimmed Can Height?”

During the can making process, the Trimmer sets the Can Height after the Bodymaker. After being washed, a few of the cans go to Quality Control. Here the Trimmed Can Height is measured, and multiple measurements are taken. 

During the can making the process the Flange is formed inside the Necker. The Flange mates with the can end at the filler. 

If the trimmed can is too high:

• You are giving away excess aluminium which can be costly.
• A tall can height leads to a wide flange.

If the trimmed can is too short:

• It can lead to a narrow flange which causes issues in getting body hoot in the double seam

Both cause issues at the filler. 

In addition, If the can is uneven, you may have issues getting it through the necker with wrinkles.

Out of specification trimmed can height can also adversely affect the overall production output by causing an enormous jam at the necker stage.

Ensuring trimmed can height is correct is crucial to avoiding the above, and this is where a range of Torus Gauging can help:

• Z338 Manual Front End Trimmed Can Gauge
• Z301 Automatic Front End Trimmed Can Gauge
