Glass Fibre '2079851475616104452 difficult demolding
Fenómeno do problema
Glass Fibre injection molded product has large demolding force, product deforms or is scratched, demolding time accounts for 30% of cycle
Análise das causas
Glass Fibre has large adhesion to mold cavity; draft angle insufficient <0.5°; cooling time insufficient, product demolded before fully solidified; ejection mechanism design unreasonable
Solução
1) Increase mold draft angle to 1-2°; 2) extend cooling time so product is fully solidified before demolding; 3) polish mold surface to Ra<0.2μm; 4) increase ejection area, use large-area ejector plate; 5) spray release agent (temporary solution)
Conclusão principal
Difficult demolding is caused by adhesion and insufficient mold design; increasing draft angle is the fundamental measure
