Atlas of Casting Defects
Negative
Slot or beveled face with characteristic grooves running the direction of the cut-off wheel
N/A
Anywhere but typically near a gate contact
N/A
N/A
Visual inspection and Penetrant inspection typically reveal cracks. Cracks form roughly 90° to stress direction.
Blade or plasma torch deflects into casting or continues into casting after cut
| Area | Possible Cause | Potential Correction |
|---|---|---|
| Other (Gating Design) | Castings too close to the runner bar/ variable distance from runner bar |
Increase gate length |
| Other (Post-Cast operation) | Incorrect part loading in cutoff fixture |
Mistake proof the holding fixture |
| Other (Post-Cast operation) | Cut-off blade flex during the cut-off |
Use different blade, change gate shape |
