The Flow front speed at center result represents the fill velocity when the flow front reaches a specific point in the center of the plastic cross-section.
This result is generated from either a Fill or Flow analysis using Midplane or Dual Domain analysis technologies. This result is available for all thermoplastic injection molding processes, including overmolding, gas, co-injection, bi-injection, and injection compression molding.
Variation in the flow front speed across the mold surface is highlighted by the Flow front speed at center result. This result highlights areas of hesitation. The variation in flow front speed can also impact on the visual quality of the finished part.
Ideally, the speed of the flow front is uniform as the part fills, especially in areas where surface appearance is important.
