PMMA Product Dimensional Stability
Problem Phenomenon
Dimensional drift of precision optical parts.
Cause Analysis
PMMA shrinkage of 0.2%~0.8% is relatively low, but moisture absorption and stress relaxation still have an impact; measurement environment is not unified.
Solution
①Unify measurement environment and aging; ②sufficient cooling; ③annealing stabilization.
Key Takeaway
Precision parts = measurement standardization.
