Die Blocked Caused by Flow Differences

It’s common to see in complicated profiles die and dies with long cantilever .

1) The main performance is the design deviation of aluminum flow ratio, the size of the chamber, the length of the local working zone, and the obstruction of the direction of aluminum runoff.  

2) Dies with long cantilever , the main reason is that the design is not reasonable, the calculation is not accurate, the flow speed of the expansion part (including various factors in the profile) is not synchronized with other.

3) Wide profile is mainly reflected in the follow-up processing of the mold, the degree of polishing smoothness, the shape processing of the cavity, the length of the working band and the transition drop caused by the depth of the electric spark, which has little to do with the design itself.  

In short, any factor that can affect the speed of flow can cause a single or multiple deviations.
