Numerical Simulation during Short-Shot Water-Assisted Injection Molding Based on the Overflow Cavity for Short-Glass Fiber-Reinforced Polypropylene

Figure 13

Effect of water injection delay time on fiber orientation distribution along the melt flow direction.

(a) numerical analysis of water injection delay time on fiber orientation

(b) SEM image of fiber orientation, the left side of each picture is the mold wall, the right side is the channel, and the three pictures of each process parameter are the near water end, the middle end and the far water end respectively from left to right (the result of 0 s the same as the result of 1 s)
