Objective of the Simulation:-

To investigate the plastic material flow inside the cavity and identify anypotential defects which may occur in the finished product.

Scope Of Analysis:-To validate the proposed gate position.

To check the filling properties of the component.

To check the temperature distribution in the component.

To check the sink mark location & intensity.

To check the air trap & weld line position in the component.

To check the deflection level in part

To suggest the findings of analysis.Analysis Methodology:-First the cad model was converted to finite element model (FEM)FILL, PACK and WARP analysis was performed on the partWe used PP SP-280T

General information

Temperature Settings:-Melt temperature = 220.0000 CIdeal cavity-side mold temperature = 40.0000 CIdeal core-side mold temperature = 40.0000 C

Filling phase results summary :Bulk temperature - maximum (at 4.347 s) = 221.2531 C

Maximum injection pressure (at 4.3470 s) = 9.9447 MPaTime at the end of filling = 4.4756 sTotal weight (part + runners) = 53.0449 gMaximum Clamp force - during filling = 2.7260 tonne

Packing phase results summary :

Clamp force - maximum (at 4.885 s) = 3.1975 tonneTotal weight - maximum (at 14.360 s) = 55.5989 gTime at the end of packing = 34.3471 s

Total weight (part + runners) = 55.4669 g

Weld Line

OBSERVATION: Main weld lines are shown as red lines. Weld line showred lines may be little visible. These lines are near on top of dog leg fitmelocations. This can be controlled during molding process and are in acceprange.

Sink Mark

The pictures show the sink index of the various region of parts.

No sink marks problem found.

As a rule of thumb-Sink Index below 3%- no visible sink marksSink index from 3 % to 5 %- acceptable level; but processcondition/part design need to be improve unless sink may occur.
