RIB/LOAD Affect On Stiffness
Nov 30, 2017

RIB/LOAD AFFECT ON STIFFNESS

A rib is oriented in such a way as to provide maximum bending stiffness to the part. By paying attention to part geometry, designers must be conscious of the orientation of the rib to the bending load or there will be no increase in stiffness.

DRAFT AND TEXTURE

Mold drafts facilitate part removal from the mold. The draft must be in an offset angle that is parallel to the mold opening and closing. The ideal draft angle for a given part depends on the depth of the part in the mold and its required end-use function.
