The Distribution of polymer A and B, laminated result is generated from a Co-injection analysis, and shows the distribution of polymer A (skin, in red color) and polymer B (core, in blue color) at laminates in the model.
For interior laminates (grid points other than 0 and 1), the blue color (core) should be bounded by red color (skin). Otherwise it indicates that a blow-through occurred. For laminates 0 and 1, only red color (skin) should be seen. Otherwise it indicates a blow-through.
Blow-through occurs when the core material, which has less desirable properties, passes the skin material in the cavity and coats the surface of the part.
