A study an optimum casting condition for manufacturing jewelry setting of Composition Pink silver 54%

Abstract

The results of the experiments were found that the temperature of the castings was higher than that of the silver alloys. The workpiece temperature is 500C, the workpiece is good 26%. The workpiece is 74%. The temperature is 550C. The workpiece is 26%. The workpiece is 74%. The temperature is 600C. The workpiece is 40%. The workpiece is 60%. The workpiece is a fin. There are many factors that cause fins on the workpiece. Use of low-strength mortar In addition, the use of excessive compression or heat transfer, resulting in the expansion and shrinkage is not equal. This causes the cracking of the metal water to expand at a temperature of 650 ° C. The fine specimen 56% of the workpiece loses 44%. This temperature results in the smallest workpiece caused by the uneven surface. Cause of the cooling rate in each part of the casting is not equal. And at 700 degrees Celsius, it is best to cast silver ornaments with pink color because the results show that the work is minimal. There are 70% good work piece 30%
