The exhaust pressing foam machine is a key piece of equipment for enhancing sponge quality. It utilizes large-diameter rollers to apply immense and uniform pressure to the sponge. Its core function is to forcibly crush the internal "closed-cell" structure of the sponge and expel the air. This process effectively eliminates the closed-cell phenomenon, transforming the sponge into an open-cell structure with superior elasticity and breathability.link:https://www.demingmachinery.com/foaming-machine/foaming-equipment/exhaust-pressing-foam-machine.html
