TL;DR
Equations to be used in Vacuum forming a ABS plastic sheet.
What are the related equations/formulas to be used in calculations of Vacuum forming an ABS plastic sheet used in manufacturing? (In our plant we use a male mold for producing the required output/product needed)
I can recall the heat transfer formulas for Conduction, convection, and Radiation. What are the other factors to consider if I were to do this study? (We use SolidEdge 2024 for designing and other related tasks)

I have made some ABS parts using vacuum casting. I hope this helps. Things to consider are material stretching and thickness, and material shrinkage. ABS has a typical shrinkage factor, usually 0.4–0.7%. This factor is crucial in mold design to ensure precise dimensions post-cooling.

Thanks. I add this considering I've only started making my study.
