1506 질문
Q
Poor surface gloss of EMA
A
Poor gloss is caused by mold roughness and crystallization scattering; mold polishing and crystallization control are key
Molds & Tooling EMA gloss mold polishing crystallization scattering nucleating agent
Q
EEA Product Elliptical Deformation
A
Elliptical deformation is caused by asymmetric demolding force; uniform ejection is key
Molds & Tooling EEA elliptical deformation symmetric ejection uniform cooling setting time
Q
EEA Product Twist Deformation
A
Twist deformation is caused by asymmetric cooling; symmetric cooling is key
Molds & Tooling EEA twist deformation symmetric cooling gate arrangement annealing
Q
EEA Insufficient Flatness
A
Insufficient flatness is caused by shrinkage differences and stress; uniform cooling and annealing are key
Molds & Tooling EEA flatness shrinkage difference uniform mold temperature annealing treatment
Q
EEA Internal Shrinkage Voids
A
Shrinkage voids are caused by thick-wall shrinkage and insufficient holding; extending holding is key
Molds & Tooling EEA shrinkage void thick wall holding time gate freezing
Q
EEA Length Out of Tolerance
A
Length out of tolerance is caused by unstable shrinkage rate; accurate shrinkage compensation is key
Molds & Tooling EEA length out of tolerance shrinkage rate mold compensation full cooling
Q
EEA Poor Surface Gloss
A
Q
EEA extruded film thick at edges and thin in the middle
A
U-shaped thickness is caused by die runner and swell difference; coat-hanger die and gap fine adjustment are the key
