Stage where most of the plastic material is attempted to be introduced into the mold, trying to fill between 95 and 98% of the total cavity volume.
- Hold PressureProcess
Pressure required to execute the holding stage. It must be greater than or equal to the pressure generated by the material inside the cavity.
- Injection SpeedProcess
Speed at which the molten material is introduced into the mold. Adequate to ensure uniform distribution and avoid defects.
