Manufacturing / Casting
Casting DFM checker.
Shares draft angle, wall uniformity and undercut detection with injection moulding, since both are tool-ejection or pattern-removal processes.
CheckWhat it doesStatus
Draft angleA wall parallel to the pattern's pull direction sticks on removal from the mould or pattern.Auto-fixed on STEP
Wall uniformityUneven wall thickness solidifies unevenly, risking shrinkage porosity and hot tears.Auto-fixed on STEP
UndercutsA feature the pattern can't pull straight out needs a core, a split pattern, or a redesign.Detected
Sharp internal corners concentrate stress and encourage hot tearing as a casting cools; a generous fillet helps, and this overlaps with the CNC tool-access check if the part is also machined after casting.
