Description

technical field

[0001] The invention relates to the field of industrial processing equipment, in particular to a supercritical foamed EVA sole molding equipment and method. Background technique

[0002] EVA resin is an ethylene-vinyl acetate copolymer, and the vinyl acetate (VA) content is generally 5% to 40%. Compared with polyethylene, EVA is widely used in foam shoes due to the introduction of vinyl acetate monomer into the molecular chain, which reduces high crystallinity and improves flexibility, impact resistance, filler compatibility and heat sealing performance. materials, functional shed film, packaging film, hot melt adhesive, wire and cable and toys and other fields.

[0003] When the EVA sole is formed, the two molds are separated, and due to the foaming of the material, it is easy to stick to the mold. It needs to be removed manually, and the sole temperature is high, which is easy to cause burns to the staff. Moreover, the soles are manually removed for many...
