Acquisition process of stoppers from mixed material agglomerate

A method of acquiring stoppers from mixed material agglomerate, the method comprising:

• in an agglomerating equipment is processed a mixture called “mass,” where the cork powder predominates, resulting from the agglomeration and mixture of the cork powder with E.V.A., and/or rubbers in general, and/or polyolefin resins, and/or thermoplastic resins, and/or other types of resins in general, crosslinker and expander;
• and that such a homogenized “mass” later passes through a cylindrical extruder in order to potentialize the mixture even more, producing rollers according to the measurement of the stopper that it is intended to be made, which are finished, expanded and reticulated in a press machine;
• where they may be pressed either horizontally or vertically, so, that already reticulated rollers are obtained. Then they are polished, acquiring a final, velvety finishing, and later they are severed into any dimensional shapes, conforming rollers which besides their perfect dimensional stabilization are ideal for the purpose that they are made for, being the case that said agglomerated and homogenized mass can also be shaped in expanded and crosslinked plates, from which, through drills, molds, and/or suitable tool equipment, the corks are obtained in the desired measures, highlighting that the present process includes the use of residues of the cork industry originated from the finishing given to stoppers, which are always polished with sandpaper, which cork powder with a thickness between 30 to 300 mesh, can not be used in traditional fabrication processes and are sent for burning.
