Poor ABS demolding (mold sticking)
Fenómeno do problema
The product adheres to the cavity or core, and is pulled injured, ejected white, or even punctured during demolding.
Análise das causas
Too high holding pressure and too high melt/mold temperature make the product's gripping force large; insufficient draft angle; poor cavity polishing or roughening; vacuum adsorption effect.
Solução
①Reduce holding pressure and melt temperature; ②ensure a draft angle of 1°~3°; ③polish the cavity to repair pull injuries; ④fully cool before mold opening; ⑤add venting to avoid vacuum adsorption.
Conclusão principal
For mold sticking, first reduce pressure and temperature, then check the draft angle and polishing.
