SUMMARY
The force required to eject a sheet metal part from a die cavity can be calculated using the coefficient of friction, surface area, elastic modulus, material type, and thickness. In this discussion, the coefficient of friction is specified as 0.35, the surface area is 521.26 mm², the elastic modulus of 3003 Aluminium is 68.9 GPa, and the material thickness is 0.7 mm. These parameters are essential for accurately determining the ejection force needed for the part.
