Systems and methods for forming various thin-walled injection molded polymeric material, including microcellular polymeric material, are described. Injection-molded containers having significant void volume (weight reduction) and surprising top load strength are produced. Deviation from average (nominal) wall thickness is reduced since injection pressure, and resulting mold core deflection, are reduced, resulting in more uniform wall thicknesses. High length-to-thickness ratios, containers having locations remote from the gate that are thicker than average wall thickness, reduced cycle times, low molding temperatures, and other features are presented. |
