UNASSIGNED: The goal of this research was to compare the sprue design\'s marginal fit to that of the other designs.
UNASSIGNED: During this investigation, we attempted to see whether the fabrication of metal copings could be improved. Three sprue designs were used in this research for the assessment of casting accuracy: normal cylindrical, funnel-shaped, and cuboidal or flattened sprue forms.
UNASSIGNED: The mean marginal disparity of nickel-chromium (Ni-Cr) alloy copings made by three distinct brands was determined to be statistically insignificant.
UNASSIGNED: Within the limitation of the study, it was concluded that the marginal accuracy of metal copings fabricated with three different brands of Ni-Cr alloy did not reveal a statistically significant result. However, out of the three different sprue designs, that is, cylindrical, cuboidal, and funnel shape, the marginal accuracy of cylindrical and cuboidal sprue designs was found to be better than that of the funnel shape sprue design because the funnel shape sprue design is narrow at the point of attachment, thereby increasing the flow pressure and decreasing the turbulence of the molten metal.
UNASSIGNED:这项研究的目的是比较浇口设计与其他设计的边际配合。
未经批准:在本次调查中,我们试图看看是否可以改善金属覆盖层的制造。在这项研究中使用了三种浇口设计来评估铸造精度:普通圆柱形,漏斗形,和立方形或扁平的浇口形式。
UNASSIGNED:由三个不同品牌制造的镍铬(Ni-Cr)合金镀层的平均边际差异被确定为统计学上无统计学意义。
未经评估:在本研究的限制范围内,结论是,用三种不同品牌的Ni-Cr合金制造的金属覆盖层的边际精度没有显示出统计学上的显着结果。然而,在三种不同的浇口设计中,也就是说,圆柱形,长方体,和漏斗形状,圆柱形和立方形浇口设计的边际精度比漏斗形浇口设计好,因为漏斗形浇口设计在连接点处较窄,从而增加流动压力并减少熔融金属的湍流。
