Click For Summary
Key equations for vacuum forming ABS plastic sheets include heat transfer formulas for conduction, convection, and radiation. Important factors to consider in the study are material stretching, thickness, and shrinkage, with ABS typically exhibiting a shrinkage factor of 0.4–0.7%. This shrinkage is vital for accurate mold design to achieve precise dimensions after cooling. The use of SolidEdge 2024 for design tasks is noted as part of the process. Understanding these aspects is essential for successful vacuum forming in manufacturing.

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.
 
My idea is that I want to use immerse Whitetail Antlers in a fishtank to measure their volumetric displacement (the Boone and Crockett system is the current record measurement standard to place in a juxtaposition with) I would use some sight glass plumbed into the side of the tank to get the change in height so that I can multiply by the tank cross-section. Simple Idea. But... Is there a simple mechanical way to amplify the height in the sight glass to increase measurement precision...
