Molding processes for BMC and SMC
BMC and SMC are molded hot. The compound flows and cures in a heated mold, and the part is still hot when it is ejected. The process you choose sets the possible part size, wall thickness, fiber length, tolerances and part cost.
SMC is almost always compression molded. BMC is injection molded for smaller, detailed parts in volume, or compression molded for thick sections and lower volumes. Most parts are then deflashed, and some are machined, fitted with inserts or painted.
