Part Geometry for Plastic Molding

Feasible geometries for IM and RIM are limited only by machine capabilities. A part is geometrically feasible for IM and RIM if and only if some machine that is included in the VPE satisfies both the following requirements:

• It is able to accommodate the horizontal and vertical dimensions of the mold base required for the part.

• It is able to provide the clamp force required for the part. (The required clamp force is a function of the part’s geometry as well as the material to be used.)

Feasible geometries for SFM must satisfy the requirements just described for IM and RIM, and must also have an average wall thickness not less than a plant-variable-specified minimum. See Additional SFM Feasibility Checks.

See GCD Extraction for Plastic Molding for more information on part geometry, and Machine Feasibility and Selection for more information on machine selection.
