Visual Inspection
Molten Wax or sticky wax drips onto the pattern during gating assembly process
| Area | Possible Cause | Potential Correction |
|---|---|---|
| Wax | Wax melting iron / torch too hot |
Reduce temperature |
| Wax | Sticky wax too hot |
Reduce to correct temperature |
| Wax | Poor gating technique |
Use a shield (aluminum foil) to prevent drips from getting on the pattern |
