dc.description.abstractThe purpose of this research was to investigate the optimum heat temperature for the EC500 wax cured basecoat extrusion from all castings without waxing in the mortar. To reduce waste when the casting mortar through the casting process Silver Sterling 925 silver jewelry company Muang District, Chiang Mai, where the waste is caused by waxing outflow. The imperfections and leave waxing inside. Experiment with high temperature heat in mortar. And analyze the quality of work surface after casting with microscope. To find defects such as droplets and porosities caused by a range of temperatures. Temperature of baking mortar There is a difference from the conventional waxing mortar temperature. That is, outflow of EC500 type wax. In the mortar to live. High heat The results of the 100 sample EC500 wax samples were tested at a temperature of 25 ° C. The mortar temperature was 700 ° C. 60 percent of waste was found, the mortar was laid at 750 ° C 54 percent of waste was found. The mortar temperature was 800 ° C 32 percent waste was found, the mortar temperature was 850° C Detecting 1 percent waste. The results of the study show that heat temperatures of up to 850 ° C can solve the problem of casting sterling silver alloys from the EC500 wax model. Finds the least waste.en_US
