Autodesk Moldflow is a simulation package for plastic injection molding.
As part of the solutions for Digital prototyping, it helps CAE analysts
and manufacturers optimize the design of plastic parts and injection molds.
In general, models of the plastic parts are created at the first stage of
product optimization and the major concern is the manufactured quality of
the parts. Once the product design is satisfactory, optimization may be
extended to mold design. However, the challenge is that models of the mold
geometry may not yet exist in the analysis models. The plastic parts sit
inside the mold geometry and have contact interfaces. If the analysis model
is replaced by a new assembly which includes the mold components, all
analyses will have to be rerun. In addition, it is also common that part
geometry is optimized as a result of the part analyses. In order to extend
analyses to molds based on legacy meshes for plastic parts, we provide an
approach to generate mold meshes incrementally by stitching new CAD or STL
bodies of the mold with existing part meshes.
