Week 8 - Challenge 1 - Draft Analysis on a Fan Cover

• Draft analysis is performed on the models to ensure a proper ejection of part from mold core, draft analysis is essential for any part which is to be manufactured in injection molding, draft angle for part should be a minimum of 3 degree, during the cooling process parts trends to adhere to the core and forcefully removing the part causes draw lines, wear and tear to mold cavity ,core and part itself.

• Draft angle is provided on both core and cavity, conversely parts manufactures with less draft angle are more expensive when compared with higher draft angles.
• Tooling axis ascertains the direction of mold cavity both for forward and withdraw form the core. To remove the part easily from core all part are given with draft angle, draft angle is analyzed in draft analysis by ‘analysis under the running point’ option.
• Creating tooling axis for a simple part is easy, where as for a complicated part(parts containing contours, ribs and taper angles), many parameters needs to taken care.
