Pressure at the end of fill Picture for Pressure at the end of fill Specification. Flow Front Temp Flow Front Temp picture The difference in temperature of flow front is 12.5℃. The distribution of the flow front temperature is uniform on most of the part, while there were local temperature drops at the small features, The minimum temperature of the part was 198.1℃. It isn’t in the range of the melt temperature, which is from 200~280 ℃. Increasing the melt temperature can solve the problem. Maximum Shear rate Shear rate picture The shear rate is uniform on the part ,while the shear rate of the gate locationThe shear rate is uniform on the part ,while the shear rate of the gate location does exceed the limited value 24000 1/s, which recommended in the material database of moldflow. The maximum shear rate is 788300 1/s at the gate location. Increasing the gate size or change the injection process could decreased the h tshear rate. Shear Stress at wall Shear stress picture The picture shows the distribution of the shear stress at wall when fulfilled. The maximum value is 0.7150 MPa. The maximum shear stress is 0.26MPa which recommended in the material database of moldflow. The maximum shear stress position is located in gate. Because the gate will be cut down, so the shear stress of product is not exceed the g permitted range. System Pressure As the picture shows, the maximum value is 47.17MPa, at 2.13 s, V/P time. Injection pressure specified at Packing is 37.74 MPa Packing Time: 10 s System Injection Pressure XY Plot (Taken at machine Nozzle) Packing profile plot Clamp Force Clamp Force XY PlotClamp Force XY Plot Max. clamp force during packing is 1310.3 tons.
