Does InspireCast account for the wax in the Investment casting process? or does it assume the mold shell has been dewaxed?
Hello Jeff,
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.
Hello everyone,
Since this post is a bit older, I would like to ask whether there is now a material available in newer versions of Inspire Mold that can be used to simulate paraffin wax as a selectable material.
Alternatively, does anyone have reliable material data that could be used to create a custom material?
My goal is to simulate the molding step, which is a critical part of the investment casting process. We currently have a mold with some surface defects, and I would like to test possible improvements in the simulation before adapting the die set.
Interestingly, using PE-LD as a substitute worked well enough to reveal issues such as warpage and air traps. However, I am not fully confident in the results regarding stress, deformation, and shrinkage.
Any help or experience with this topic would be greatly appreciated.
Janik
