Dimensional accuracy retention of POM products
Problem Phenomenon
Long-term dimensional changes of POM high-precision parts.
Cause Analysis
Moisture absorption (although small) and stress relaxation cause slight long-term dimensional changes.
Solution
Annealing treatment of precision parts to stabilize dimensions; reserve dimensional tolerances.
Key Takeaway
The long-term dimensional stability of POM is a requirement of precision machinery.
