Abstract:
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.
Abstract:
A method for making a shoe sole includes step of preparing various types of foamable material; step of making the foamable material into particles; step of preparing a mold having a cavity in which the foamable material is being put; and step of foaming the foamable material in the cavity and obtaining a sole. The foamable material has different resilient coefficients but the same foaming rate so that the sole can be a made by a single foaming process and includes various resilient features.
Abstract:
A centrifugal fan module, a heat dissipation device having the same and an electric device having the heat dissipation device are provided, in which the heat dissipation device includes a fin module and a centrifugal fan module including a volute-shaped frame and a centrifugal fan pivoted in the volute-shaped frame. The volute-shaped frame includes an air inlet, a larger air outlet and a smaller air outlet. The air inlet and the smaller air outlet are both on the same surface of the volute-shaped frame. The larger air outlet is coupled to the fin module. The smaller air outlet is arranged correspondingly to a maximum wind-speed flowing path of the centrifugal fan.

Abstract:
A method for manufacturing EVA outsoles includes step 1 to mix EVA and foaming agent to become a mixture; step 2 to press the mixture to be a plate; step 3 to cut the plate into strips; step 4 to overlap the strips to a desired weight; step 5 to heat the overlapped strips in step 4 in a mold to form an outsole, and step 6 to trim the outsoles.
