The actual injection pressure will be about 1.2~1.5 times of analysis value
Flow Front Temperature
The flow front temperature distributes evenly
Flow front temperature/ ℃ 284.9 ~ 286.1
Only have 2ºdraft angle might scratch it , suggest to increase to 3ºcavity draft angle and polish on the pointeMdF: Done surfaces.
