Glass Fibre angle deviation
Problem Phenomenon
Glass Fibre product angle deviation >1°, exceeding ±0.5° tolerance
Cause Analysis
Uneven shrinkage causes angle change; mold angle design did not consider Glass Fibre shrinkage compensation; product deforms during demolding
Solution
1) Mold angle pre-compensates Glass Fibre shrinkage rate; 2) extend cooling time to ensure setting before demolding; 3) uniform cooling to reduce shrinkage difference
Key Takeaway
Angle deviation is caused by shrinkage and insufficient design compensation; pre-compensation is key
