Material Data

General: Recommended Processing:

Rheology: PVT properties:

Specification:

Material is pp ， simulation infromation can find in Moldflow material data sheet.

Initial Nozzle/Gate Locations and sizes

Gate dimension 1.5MM Cold/Hot runner& dimension Hotrunner 10

Gate type : 2 cavities hot runner Valve control No

Specification: Gate location and size decide is based on mold design experience, Part modify refer to moldflow analysis and T0 samples.

D10

Fill time - AnimateShift+F5 watch the animation

Short shot No short shot, fill is keep balance

Specification: Blue to red stand filling order, for evaluate filling balance, red area is the finished at the end.

Fill time - Contour

Short shot No short shot, fill is keep balance

Specification: Blue to red stand filling order, for evaluate filling balance, red area is the finished at the end.

Bulk temperature at end of fill

Specification: Temp keep balance, no obvious temp difference.

Pressure at V/P switchover

V/P control Filling control Volume % at V/P 97.33%

Specification: From thebmV/P pressure, pressure keep balance

Pressure at the end of fill

Specification: Analysis by synthesis, pressure keep balance

System Pressure(Nozzle Pressure & Packing pressure ）

Max. Pressure Time 1.62s Max. Pressure 55MPa

Packing time 10s Packing pressure 44MPa

Specification: Max. pressure 55MPa

Flow Front Temp

Flow front Temp. Difference ℃ Temp. Diff. at A surf.(230.7-111）

Recommended material Temp.

220 -260℃ ℃ Specification: Flow front Temp in the range of recommended material temp.

Clamp Force

Max. clamp force 433tonne Clamp force limit tonne

Specification: injection machine tonne meet to molding requirement.

Air Traps

Specification: The part red circle pink point it indicate prelim air trapping location, all the place should be considerate add air veting.

Weld Lines

Specification: Color lines indicate weld lines location.

Volumetric shrinkage at ejection

Specification: The max. shringkage is 13.18%, Min shringkage is -0.4% at ejection. if increase the gate size , extend packing time can reduce volumetric shrinkage.

Sink Mark Depth

Specification: The part sink mark is not clear, max sink mark index 4.5%, min sink mark index -5.6%
