Double-layer and multi-layer EVA foaming press selectionA double-layer model focuses on two molds, fast opening and part removal after expansion. A multi-layer model requires review of platen layers, inter-layer daylight, mold thickness and batch density. Both must be trialed against expansion ratio, heating time, cooling and rebound conditions.Provide the EVA or rubber compound, sheet or part dimensions, expansion ratio, mold thickness and weight, target layer count and cooling method so daylight, platen configuration and production flow can be confirmed.Review machines: double-layer EVA foaming press · multi-layer EVA foaming press
