The Flow front speed result represents the velocity of the flow front advancement when the flow front reaches a specific point in the mold cavity.
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 result. This result highlights areas of hesitation or acceleration. Variation in flow front speed can impact 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.
