Hello Jeff,

why do you need wax for Investment casting simulations? Wax is used only for making the shell mold, After autoclaving, it is gone and only remains the ceramic shell mold.

 

Usually, in IC the mold is shell is dewaxed, we don't consider wax, as when we pour the molten, it is assumed that the mold is dewaxed.

Mainly was asking to get more clarification on the process.  I did not think wax would come into play in a simulation but someone had asked me that question.  Thank you for your answer.

Dear Jeff, If you are interested in wax injection process, following may help you as well

 

In general, in some producer of investment casting products, only one team may manage the all processes from wax part to casting part. So the team want to know whether simulation softwares are able to analyze the wax injection or not. Because some of their biggest problems are shrinkage, warpage, air traps... on the wax part to produce a shell mold successfully. As you know wax injection stage is initial step of investment casting.

I have learnt that wax material(sometimes called paraffin wax) is chemically no different than Polyethylene, the molecular weight is just much lower than industrial injection molding grades.

As long as you have wax materials' parameters you can simulate the molding of the (thermoplastic) polymer by using Altair Inspire Mold(plastic injection molding simulation software)

We can say that Altair Unit system provides maximum efficient for its customers because both Inspire Cast and Inspire Mold can be used under one license.
