An apparatus for molding a proppant is disclosed. The apparatus comprises a first member comprising a manifold for channeling a plastic fluid to a ca vity block, with the cavity block containing a plurality of semi-spherical c avities. The apparatus further includes a second member that comprises a mov able plate for engaging with the first member, with the movable plate having an opening therein, and a core block positioned within the opening, with th e core block containing a plurality of reciprocal semi-spherical cavities co nfigured to engage the semi-spherical cavities of the cavity block so that a plurality of spheres are formed, with the core block further containing a p lurality of arm cavities that link the plurality of spheres so that a star c luster (which links the proppants) is formed. A method of manufacturing prop pants and a method of using the proppants is also disclosed.
