I did a mold-flow analysis by using SW plastics on a simple round vial with bottom center gate. I tried to determine the required injection pressure and cycle time. The following are the results:
Auto-Solid Mesh: 1000psi and 44sec cycle time
Manual Mesh: 4330psi and 30set cycle time (used smaller elements of about 0.75mm size near the ribs & 1.0mm for the rest)
I discussed this issue with SoildWorks, who suggested to use the following setting -
Manual Mesh: 7100psi and 37set cycle time (used 1.3mm triangle mesh and use the "auto" setting for local Refinement)
Which data I can use...................................
Thanks
Wenzhen Cheng,
Are you sure that you used the same material and the same process settings for all three cases? I would not expect to see such large differences due to meshing, but I am not a user of SolidWorks Plastics, so I may be completely wrong.
How thick is your typical wall? What is the diameter of the part? What is the length/height? For a simple round vial, what do you mean by ribs?
