Case Study – RE-Design of the Vacuum Chamber

October 8, 2023by mnes
Customer Credentials

 

A leading industrial equipment manufacturer specializing in precision automation.

 

Situation

One of their pick-and-place pad systems suffered a critical shaft failure, causing an unexpected production shutdown. The system was operating at peak designed load, but the shaft could not withstand the cyclic stress over time. The customer needed an urgent redesign to ensure long-term reliability without excessive modifications.

 

Implications
  • Production downtime led to financial losses and missed deadlines.
  • Continuous failures could damage the company’s reputation.
  • High maintenance costs made the current design unsustainable.

 

The Outcome

MNES performed a Finite Element Analysis (FEA) iteration to develop an optimized solution:

  • Strengthened the shaft design with improved load-bearing capacity.
  • Implemented an alternative extension spring mechanism to reduce stress.
  • Ensured the new design met fatigue limits and operated reliably for at least two years.
