Question

Arrange the following as per the steps followed in Aluminium Casting by the Indirect lost-wax. A. The entire mass is encased in a plaster of Paris investment. B. All the plaster investment material has been broken away from casting. C. Covering the plaster form with a thin wax coating. D. Gates, channels, and risers are then attached to the model. E. The mold is then baked to melt away the wax and molten metal is poured to occupy the space vacated by the ‘lost' wax. Choose the correct answer from the options given below:

• A. A, B, E, C, D
• B. B, E, A, D, C
• C. C, D, A, E, B
• D. D, C, B, E, A

Hint:

Remember the sequence of Indirect Lost-Wax Casting: \[ \boxed{ \begin{aligned} \text{Wax Coating} &\rightarrow \text{Prepare Wax Model}, \text{Gates and Risers} &\rightarrow \text{Provide Metal Flow}, \text{Investment} &\rightarrow \text{Plaster of Paris}, \text{Burnout} &\rightarrow \text{Wax Melts, Metal Poured}, \text{Break Investment} &\rightarrow \text{Finished Casting}. \end{aligned} } \] Mnemonic: “Wax $\rightarrow$ Gates $\rightarrow$ Investment $\rightarrow$ Burnout $\rightarrow$ Break.”
