Diagnosing and fixing common molding defects
| Defect | Cause | Solution |
|---|---|---|
| Sink Marks | Insufficient packing | Increase hold pressure, reduce thickness |
| Flash | High pressure, mold wear | Reduce pressure, repair parting line |
| Short Shot | Insufficient material | Increase shot size, raise temp |
| Warpage | Non-uniform cooling | Balance cooling, optimize gate |
| Burn Marks | Trapped air | Improve venting, reduce speed |
| Weld Lines | Flow front meeting | Increase melt temp, reposition gate |
