Uneven transparency of PCTG injection parts
Problem Phenomenon
Obvious transparency differences in different areas of the same product.
Cause Analysis
Different cooling rates in different areas cause microstructural differences; different thicknesses cause different light refraction.
Solution
Uniform mold temperature; uniform wall thickness design; gate optimization.
Key Takeaway
PCTG transparency uniformity requires control and cooling.
