According to change of the Liquid/powder (L/P) ratio difference, the number of casting nodules formed on the casting body surfaces was checked through the mixing method and wetting agent exist.
The results obtained are as follows.
1. The nodules formed on the casting surfaces, through applying with wetting agent on the wax patterns, are examined by hand mixing.
It is proposed that the L/P ratio 0.16 is the standard by manufacturer.
In case of the L/P ratio is 0.14, 0.15, the casting nodules are increased with 37%, 13%, and in case of the L/P ratio is 0.17, 0.18, the casting nodules are decreased with 13%, 28%, respectively.
2. The nodules formed on the casting surfaces, through applying without wetting agent on the wax patterns, are examined by hand mixing.
It is proposed that the L/P ratio 0.16 is the standard by manufacturer.
In case of the L/P ratio is 0.14, 0.15, the casting nodules are increased with 61 %, 14%, and in case of the L/P ratio is 0. 17, 0. 18, the casting nodules are decreased with 25%, 30%, respectively.
3. The nodules formed on the casting- surfaces, through applying with wetting agent on the wax patterns, are examined by machine mixing.
It is proposed that the L/P ratio 0.16 is standard by manufacturer.
In case of the L/P ratio is 0. 14, 0. 15, the casting nodules are increased with 39%, 25%, and in case of the L/P ratio is 0.17, 0.18, the casting nodules are decreased with 7%, 21%, respectively.
4. The nodules formed on the casting surfaces, through applying without wetting agent on the wax patterns, are examined by machine mixing.
It is proposed that the L/P ratio 0.16 is standard by manufacturer.
In case of the L/P ratio is 0.14, 0.15, the casting nodules are increased with 73%, 41%, and in case of the L/P ratio is 0.17, 0.18, the casting nodules are decreased with 15%, 23%, respectively.
5. The number of casting nodules formed by hand mixing, through applying with wetting agent is more effective in reduce than that applying without wetting agent.
In case of the L/P ratio is 0.14, 0.15, 0.16, 0.17, 0.18, the casting nodules are decreased with 94%, 67%, 66%, 43%, 61%, respectively.
6. The number of casting nodules formed by machine mixing, through applying with wetting agent is more effective in reduce than that applying without wetting agent.
In case of the L/P ratio is 0.14, 0.15, 0.16, 0.17, 0.18, the casting nodules are decreased with 91%, 74%, 54%, 41%, 50%, respectively.
7. It is investigated that the casting nodules formed by machine mixing is better than hand mixing through applying with wetting agent.
In case of the L/P ratio 0.14, 0.15, 0.16, 0.17, 0.18, the casting nodules are decreased with 36%, 25%, 38%, 29%, 26%, respectively.
8. It is investigated that the casting nodules formed by machine mixing is better than hand mixing through applying with wetting agent.
In case of the L/P ratio 0.14, 0. 15, 0. 16, 0.17, 0. 18, the casting nodules are decreased with 38%, 20%, 49%, 31%, 35%, respectively.
