Abstract
A shim stack foaming die for making foam slabs comprises a plurality of shims that are layered together under pressure to form a shim stack, wherein the shims combine to collectively define a plurality of die orifices in a working face, to define a main body of the shim stack foaming die, and also to define a plurality of die cavity that is fluidly connected to the plurality of die orifices. And articles foamed from the shim stack foaming die have found wide use in various applications, thermal or acoustic insulation, reinforcing layers and/or space-filling layers, and so on.
