An apparatus and system for molding a flow of moldable material under the application of shear, compressive and/or tensile loads. The apparatus includes a mold housing that has a flow of moldable material supplied to it. First and second boundary elements, located within the mold housing, define the first and second side of the flow of moldable material. A driver in contact withthe first boundary element deflects the first boundary element in a direction substantially perpendicular to the flow of the moldable material. The deflectionof the first boundary element imposes shear, compressive and tensile loads on the flow. The applied shear, compressive and tensile loads produce mixing of the moldable flow of material and can also be controlled to effect the rheological properties of the moldable material. A flexible joint is incorporated into the apparatus to allow the first boundary element to deflect. A system is also disclosed which includes the steps of mixing a first material component anda second material component so as to produce a mixture. The mixture is melted to form a moldable material. The moldable material is conveyed between first and second boundary elements of the molding apparatus. A portion of the first boundary element is deflected in a direction substantially perpendicular to the flow of moldable material. The deflection of the first boundary element imposes shear, compressive and tensile loads on the flow of moldable material. The moldable material is then cured into a final product.
