Method for producing an EVA sole material |
摘要 |
A method for producing an EVA sole material comprises the steps of uniformly mixing EVA (ethylene-vinylacetate) material and foam material sufficiently as a mixture material; using at least one rollers rolling through the mixture material as a sheet; cutting the sheet into a plurality of sub-sheets; overlapping some of the plurality of sub-sheets to have a predetermined weight; placing the overlapping sub-sheets into a sealed space in a mold having a texture of a shoe; venting and vacuuming air within the space; foaming the sub-sheets in the mold; vacuuming the sub-sheets in the mold; transferring the sub-sheets through a transfer belt with different temperature stages of 75° C., 65° C., 55° C., 35° C. sequentially through a time period of about 40 minutes; wherein each temperature being retained another predetermined time period in the transfer belt; and checking and packing the produced sub-sheets.
