请問高手

在决定注射时间（Injection time）,是以Molding Window分析结果中的Qulity (Molding window):xyplot中最佳品质时注射时间决定，
还是Minimum flow front temperation(molding window):xyplot调节flow front temperation 为melt temperation时的注射时间决定

For me, the injection time of a part is decided based on four mains areas:

1. Material (which is related to its viscocity and flow length)
2. Size and general thickness of the part (which is related to viscocity and flow length of the material)
3. Pressure (should be below 70 MPa if runner is ignored)
4. Problem of short shot (due to complexity of the part and freeze-off problem)
