LOST WAX CASTING PROCESS |
| 摘要 |
The pins which are used for the support of a core in a lost wax casing process are provided with caps. The caps provide sufficient surface area for encapsulation by ceramic slurry. Heat loss from the metal melt via the pins is thus obviated along with undesirable grain nucleation. |
