Glass Fibre internal density uneven
Problem Phenomenon
Glass Fibre product different parts density difference ±3%
Cause Analysis
Holding pressure transmission uneven, region far from gate holding insufficient, density low; crystallinity regional difference causes different density
Solution
1) Optimize gate design to make holding pressure transmit uniformly; 2) uniform mold temperature to reduce crystallization difference; 3) multi-point gates improve holding distribution
Key Takeaway
Uneven density is caused by uneven holding; optimizing gate design is key
