Distinct molding microstructures were obtained by superimposing a mold surface rotation action in different rotation modes during the filling stage of a center\u2010gated disk. For this, disks were injected in the special molding tool\u2014the RCE mold\u2014with distinct filling sequences (stationary, continuous, stepped, and pulsed rotation modes) for two different thicknesses (1.5 and 2.5 mm) in a propylene homopolymer. This enables the development of a wide range of microstructures, which were characterized by polarized light microscopy. The mechanical behavior of the moldings was assessed by tensile and impact testing. The results are presented in terms of the relationships between the developed microstructure and the assessed mechanical properties. The imposition of a rotation action of the molds wall influences the development of the microstructure, and hence the mechanical properties of the moldings.<\/jats:p><jats:p><jats:boxed-text content-type=\"graphic\" position=\"anchor\"><jats:caption><jats:p>Effect of the rotating mode: stationary, continuous (R), stepped (RS), and pulsed modes (RC), at 150 rpm on the microstructure at position P2 (cuts to transversal flow direction).
