Manufacture of foamed ethylene vinyl acetate soles, mixes plastic and foaming agent, presses into panel, cuts into strips, stacks, hot-molds and trims

摘要

The ethylene vinyl acetate is mixed with foaming agent (stage 1). It is pressed to make a panel (stage 2) which is cut into strips (stage 3). The strips are stacked in groups, each group having a desired weight (stage 4). The stacks are heated in a mold to form the sole (5). The moldings are trimmed (stage 6).
