The EVA Foam Sheet Calendering Machine is a heavy-duty industrial machine designed for producing uniform EVA foam sheets used in shoe insoles, midsoles, and cushioning components. Through precision-controlled heated rollers, raw EVA compound is calendered into sheets of consistent thickness, density, and surface finish.
This machine features a four-roll inverted L-type calender configuration, with individually temperature-controlled rolls (up to 200°C) ensuring optimal material flow and surface quality. The gap between rollers is digitally adjustable from 0.5mm to 50mm, accommodating a wide range of product specifications. A motorized nip adjustment system maintains precise gap control under varying loads.
The integrated cooling section rapidly stabilizes the calendered sheet, preventing post-processing shrinkage and ensuring dimensional accuracy. Production speeds of 5-25m/min can be achieved depending on sheet thickness and material formulation. This machine is the backbone of any EVA shoe material production line.
