Q
Glass Fibre poor fatigue resistance
A
Poor fatigue resistance is caused by insufficient recovery and fast crack propagation; raising crosslinking is key
Molds & Tooling Glass Fibrefatigue resistancecrosslinking degreemolecular weightstress concentration
Q
Glass Fibre poor surface gloss
A
Poor gloss is caused by mold roughness and crystallization scattering; polishing mold and controlling crystallization are key
Molds & Tooling Glass Fibreglossmold polishingcrystallization scatteringnucleating agent
Q
Glass Fibre angle deviation
A
Angle deviation is caused by shrinkage and insufficient design compensation; pre-compensation is key
Molds & Tooling Glass Fibreangle deviationshrinkage compensationmold designfull cooling
Q
Glass Fibre length out of tolerance
A
Length out of tolerance is caused by unstable shrinkage rate; precise shrinkage compensation is key

Q
DSTDP product elliptical deformation
A
Elliptical deformation is caused by asymmetric demolding force; uniform ejection is key

Q
DSTDP product twisting deformation
A
Twisting deformation is caused by asymmetric cooling; symmetric cooling is key

Q
DSTDP insufficient flatness
A
Insufficient flatness is caused by shrinkage difference and stress; uniform cooling and annealing are key

Q
DSTDP internal shrinkage void
A
Shrinkage void is caused by thick-wall shrinkage and insufficient holding; extending holding is key
