EVA Twice Foaming Press Machine

PE Twice Foaming Press Machine   EVA Secondary Foaming Machine is used for high rate foaming of EVA, PE, EPDM, SBR rubber and plastic materials.(Expansion rate:25-45 times). It's a kind of rubber and plastic foaming machine. Normally this machine works after EVA Foaming Machine.   The production process of EVA foam mainly includes the following steps: 1. Raw material preparation: Mix ethylene (E) and vinyl acetate (VA) in a certain proportion to form ethylene vinyl acetate copolymer (EVA) particles, which are the basic raw materials for EVA foam. At the same time, according to the specific needs of the product, appropriate amounts of foaming agents, stabilizers, lubricants, coloring agents and other auxiliary materials will be added to improve the performance and appearance of the foam. 2. Material mixing: Put the prepared EVA particles and various auxiliary materials into a mixer or blender for thorough mixing, so that each component is evenly distributed and forms a uniformly mixed…
