Load the tool上模12.) Plot the viscosity vs. shear rate绘制粘度V剪切率曲线13.) Once a curve has been created, pick a location at which the curve begins to brea找出曲线的拐点（趋于平缓部分）14.) Mark this location in the cell titled 'break point'标注此位置为拐点 并填入break point表格7.) Record the 'Fill Time', 'Peak Transfer Pressure' and part weight in spreadsheet alo记录各个注塑速度对应下的填充时间、峰值切换压力、零件重量；8.) On successive shots decrease the injection speed in nominal increments按预定的步长逐步减小注塑速度9.) Record the fill time, pressure at transfer and weight after every adjustment记录每一步的填充时间、切换压力和重量10.) Repeat this procedure until the injection speed is too slow to fill the part重复上述步骤，直到注塑速度慢到无法充满产品11.)...
