Elliptical Deformation of CMC Products
Problem Phenomenon
Out-of-roundness of CMC circular products after demolding >1.03
Cause Analysis
Demolding force is asymmetric and the product deforms under lateral force; cooling is uneven and shrinkage differs in each direction
Solution
1)Uniform ejection design with 8-point ejection to avoid lateral force; 2)Annular uniform cooling; 3)Extend cooling time for full setting
Key Takeaway
Elliptical deformation is caused by asymmetric demolding force; uniform ejection is the key
