The Bubble radius result shows the size of bubble radius distribution across the part.
It is generated from a Microcellular analysis using Midplane or Dual Domain analysis technology.
Ideally, the part should consist of uniformly distributed bubbles, and the radius of each bubble is consistent in size. Naturally, the radius of the bubble will be smaller around the gate area where the pressure is highest.
Through the control of the gas concentration injected into the polymer, the size of the bubbles either increases or decreases. Typically the recommended concentration of gas is about 0-1% of the part.
