After further analysis, the client discovered that the rounded corner was smaller than what was specified in the 3D data (3D data R1.8 vs. measured size R1). The the round corner being too small led to stress concentration and cracking.
An Internal Meeting Was Held Once We Received The Feedback. We Determined That The Round Corner R1 Was Not The Cause Of The Crack.
Force Is Required To Assemble Both Parts, Causing Significant Stress In The Plastic Shell Concentrated At The Rounded Corner. This Was Found To Be The Root Cause Of The Crack. We Submitted Our Analysis Report To The Client Along With A Suggested Improvement Plan.
The Improvement Plan Was Approved And The Crack Issue Never Occurred Again.
