Bubble radius, final result

The Bubble radius, final result shows the final radial size of the bubble at the end of cooling (the bubble is assumed to be spherical).

It is generated from a Microcellular analysis using Midplane or Dual Domain analysis technology.

Using this result

While using the Bubble radius, final result, it is better to have a small bubble uniformly distributed throughout the part. However, in reality it is more common to have the bubble size smaller at the surface, and larger at the core.

Things to look for

• The amount of bubble growth and the radius for each bubble depends on the amount of plastic injected versus the amount of gas concentration. If not enough gas is injected, the part will short shot. If too much gas is injected, it may cause a deterioration of the finished surface.
• It is better to have a small bubble uniformly distributed throughout the part.
