Moldflow Insight and HTV silicone rubber

[Anonymous]

Hi everyone !

Hope you are all well. 

I would like to know if it is possible to work with HTV (High Temperature Vulcanized Silicon Rubber) with Moldflow Insight ? 

Thanks for your answers.

Best Regards,

Hi Pauline,

as I understand the process the HTV material comes in blocks that are compressed.

Wacker reference : Solid silicone rubber (HTV) – High-Temperature Vulcanizing Silicone Rubbers

In such a case, I think reactive compression molding could be a way forward for you.

Have a look at the tutorial:
Compression Molding

Compression molding analysis results

Video:

Compression and Injection Compression Molding with Simulation Moldflow Insight

Hope this helps.

Hi Berndt, 

Thanks for your answer ! 

So if I understand well, I will be able to use HTV silicone rubber by using the compression molding analysis of Moldflow Insight ? 

I will try that, thanks again !

Hi Pauline,
yes, I believe so, and you need Moldflow Insight Ultimate

See:

Compare products Moldflow Insight and Moldflow Adviser

Further, you need material data for thermoset/reactive of HTV.
Could not find such in official Moldflow material database for reactive materials.
Check with material supplier if they have an .udb-file for simulation or could suggest an equvivalent material.

Step through the tutorial for compression molding with the available model to download, and test a reactive material to get the hint of it.
