9.Hole Length
Making a good hole in a casting is dependent on the integrity of the shell. The ratio of holediameter to length is important in determining what can be offered. Blind holes must have aradius at the top and the bottom of the hole to insure that a strong core is built for castingpurposes and to insure the best possible casting
Hole Type | Size Range | Length to Dia.Ratio |
Thru | 2 to 3 | ≤2 |
| 4 to 7 | ≤5 |
| ≥8 | ≤10 |
Blind | 2 to 3 | ≤1 |
| 4 to 7 | ≤2.5 |
| ≥8 | ≤3.5 |
