Despite it meats, compression molding has limitations: it is slower than injection molding for high- volume production, and it struggles with highly intricate factures such as thin ribs, undercuts, or fine surface textures. These consilints have copern thee development of hybrid techniques that combinane compression with methods to accesse both structural integray and dimethn intricacy.
