Why Your Manufacturer Hates “Zero Draft”: The Physics of Ejection
Designers love 90-degree angles; manufacturers fear them. We explain the physics of shrinkage, why “Zero Draft” leads to drag marks and stuck castings, and how to calculate the correct draft angle for VDI textures. We see this note on 2D drawings every single day:“Note: All vertical walls to be 90°. Zero draft allowed.” To a […]
