This Sponge Production Machine makes the sponge foam production process more efficient and cost-effective. The production process is automated, and there is minimal human effort required. The machines are also designed to produce sponges at a faster rate(Foaming speed: 2000rpm~7500rpm), which means that large quantities can be produced in a shorter period.
