PP Draft Angle 1-2°
Fenómeno del problema
PP draft angle 1-2°; increase for textured surfaces; demolding and deformation.
Análisis de la causa
PP draft angle 1-2°; increase for textured surfaces; smooth demolding; ejection deformation; surface quality; design specification.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone
Solución
①Draft angle 1-2°; ②Increase for textured surfaces; ③Ejection system; ④Deformation monitoring; ⑤Design specification.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusión clave
PP draft angle is a design specification; textured surface compensation; ejection and surface are equally important.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
