摘要： A method may comprise generating a first electronic model of a workpiece to be manufactured using an injection-molding process. The first electronic model may then be analyzed and the workpiece in the first electronic model may then be selectively distorted according to the analysis. A second electronic model of the distorted workpiece may then be generated. The workpiece may then be injection-molded within a mold generated using the second electronic model. Thereafter, the workpiece may be cooled such that the injection-molded workpiece gradually assumes the shape or substantially the shape of the workpiece in the first electronic model.

A three-dimensional CAD model is identified representing an injection mold cavity. The mold cavity includes a location of at least one gate. A potential fill pattern is determined for injection of a material into the injection mold cavity. The determined fill pattern is based at least in part on the geometry and dimensions of the modeled mold cavity and the location of the at least one gate. A strip model of the CAD model is generated based at least in part on the determined fill pattern. The strip model is used to perform a strip analysis simulating injection of the material within the injection mold cavity.
