4 cavity filling pattern - imbalance

[jhkim4]

 

I have carried out the moldflow for 4 cavities by using fusion mesh.
First result all cavities show similar filling pattern.
but second result shows imbalance filling pattern.

wow

1. It should not happen in midplane/fusion mesh.   Provided you have created 1 cavity with part of fusion mesh and feed system with beam elements. Then reflect to create 4 cavity layout.

2. If you have cad model with 4 cavity layout, then imported in moldflow and meshed the shot model, then their might be variation in mesh, thickness captured in each cavity. That difference will create imblance.

3. In 3d, it can happen as it captures, shear heating induced imblance.

Dear Madhukeshwar Talwar,

Why not?
This mash type is Fusion.
It was a true.

I wanted to say that the moldflow flow pattern  shows similar the actual flow pattern by molding condition of moldflow.

As you see this picture.
This mash type was fusion mash.
Case 1 and Case 2 mash type were same.

Case 1- Auto condition

Case 2 - Actual molding condition of a little modification

Each case applied to different injection conditions.

I wondered it.
How to use molding condition on Moldflow?

[madhukeshwart]

1. in option 2, seems to be some problem with mesh/thickness capture. NOt sure

2. Use same mesh for both the options.

3. Whats changes you made in molding conditions?

I'm sorry for late reply.

1. in option 2, seems to be some problem with mesh/thickness capture. NOt sure

→ No option and Thickness does not change.

2. Use same mesh for both the options.

→ Case 1 and case 2 are same mesh type.

3. Whats changes you made in molding conditions?

→Have you ever compared Actual molding condition with Moldflow molding condition?
    If you've tried,You will know.
    Please try and you can ask me.

Dear Madhukeshwar Talwar,

I will delete the relevant product photos.
Thank you for your understanding.

I did not lie about the options and mesh type.
I wanted to talk about injection molding condition.

I was curious about these things.

How to use to compare actual injection conditions and Moldflow injection condition?

Have a nice weekend!

Thanks and Regards
