Methods are provided for forming a plurality of air diffusers from a single fiberglass and foil blank (30). At an automated pre-forming station (14) upstream of a molding station (16), a blank has pressed therein two air diffuser patterns (50) at a middle portion (42), two patterns at a first catercorner portion (40) and two patterns at a second catercorner portion (44) and the pressing of each set of two patterns occurs substantially simultaneously to prevent the foil from delaminating from the fiberglass. Thereafter, the blank is fed to a molding station that applies a significantly larger pressing force and heats the blank to form six air diffusers. Perforations are cut in the blank to facilitate separation of the air diffusers in a trimming station (18) downstream of the molding station: Preferred pressing of air diffuser patterns occurs with pneumatic actuated male, and female air diffuser pattern molds that are sequentially operated in accordance with a desired pattern.
