Rubber Compression Moulding

[ulloap]

Hi Guys,

I need to make a finite element analysis for a rubber compression mold through Abaqus -I was trying but failed-,I dont really understand, how could I do it, let give you a little summary, of it.

Process
A pre-weighed, generally preformed piece of material / compound is placed in the mould : the mould is closed, with the sample under pressure as it vulcanizes Cavity pressure is maintained by slightly over filling the mould & holding it closed in a hydraulic press. Constant heat is provided by electric heatess, thermic fluid or steam

Best Regards.

That actually sounds like a challenging problem :(

The suspect that that main problem is related element distortions. I recommend that you try to use ALE adaptive meshing and ABAQUS/Explicit. You will also need to use an appropriate material model that captures the temperature dependence of the material.

Let us know how it goes, or if you have more questions.

Thanks Jorgen,

I´ll follow the recommendations that you made, also I keep inform you about the process.
