Radius Comment ( ):
Please refer to updated 3D sent on
Suggest add plastic at the red area to place a insert pin(1mm) for venting.

7. Draft Checked Ok Fix side Moving side EM: 25/01/2017
We will leave this feature off the tool at first and after provide parts they will decide if they need or not. Tony will provide updated drawings.

Core sub insert will including 3 degree.
EM: 25/01/2017
We want to make core sub insert with Stripper plate.
Is it passable extrude more gate rib 0.5mm avoid undercut issue.

11. Gate point suggestion EM: 25/01/2017 Changed to sub gate Manifold
Radius Comment ( ):
OK.
Action slider
Hot Tip
Tab gate
EM: 25/01/2017
Changed to sub gate

12. Ejector mark location Stripper Plate Core sub inser Ejector Dia 3(6x)
Ejector Dia 8(4x) for Stripper Plate
Stripper Plate
Ejector Sleeve
O.D=4.5 I.D=2.5 (2x)
Core sub inser
Radius Comment ( ):
Is it possible to change the middle ejector pin to 2 ejector pins aside (in purple).
Leave the middle area for marking.
Radius Comment ( ):
OK.
Excel comment –
We will make 2 ejector pin on middle (avoid the cooling channel)
And make the material identification on middle also

13. SURFACE/TEXTURE/FINISHING REQUIREMENTS
Green color area B2 polishing
Blue color area Texture YS1281-A
Texture YS1281-A
Fix Half Finishing:
Moving Half Finishing:
Radius Comment ( ):
OK. B2

14. PARTS MARKING Suggest marking area >PC<
Radius Comment ( ):
Suggest the purple area for material identification code.
Excel comment –
The marking can be make on there
Radius Comment ( ):
OK.

15. PRELIMINARY MOULD LAYOUT ESTIMATION
Mould base size: W300(250) x L300 x H441mm

17. MOLDFLOW ANALYZE：
Material：PC Makolon 2407

18. MOLDFLOW ANALYZE：Fill time

19. MOLDFLOW ANALYZE：Fill time
Radius Comment ( ):
OK.
Bad welding (There had slider parting, it will some help for flowing)

20. MOLDFLOW ANALYZE：Air traps
Air traps issues can add vent line in slider for solve it. And please add vent pin into ribs.
Radius Comment ( ):
Vent pins will be added as per slide 6.
Radius Comment ( ):
Please refer to updated 3D sent on

21. MOLDFLOW ANALYZE：Temperature at flow front
The temperature dropped rapidly
Radius Comment ( ):
What’s the down side if flow front temperature more than 10 degree?
Radius Comment ( ):
Let’s keep current geometry and review the actual off tool parts.
May require adjusting molding parameters to improve.
Temperature at flow front between to degree,
Temperature different large than 10 degree, a little bit big different.
Remark：Melt temperature-300 degree.

22. MOLDFLOW ANALYZE：Sink marks estimate
Radius Comment ( ):
There is constraint in geometry.
Let’s keep current geometry and review the actual off tool parts.
May require adjusting molding parameters to improve.
Sink marks great

23. MOLDFLOW ANALYZE ： Deflection all effects
Radius Comment ( ):
OK.
Some deflection. It may by venting line solve.
Reduced the sink mark factor(0.6%), The highest value of deflection is 0.59mm 。
