塑料管生产必须使用偏心环形模头，以补偿冷却室中的重力流。本文在双极柱坐标系下对牛顿流体和幂律流体分别求得了代数解析解.提供了偏心模头周围的无偏差平均速度分布，以帮助塑料管工程师确定所需的偏心度。在弯曲软管制造中，模具中心件被制成偏心的以引起弯曲。绘制了无偏心的曲率半径，以帮助弯曲软管制造商选择适当的模具偏心。
Plastic pipe production must use annular dies with eccentricity to compensate for gravity flow in the cooling chamber. Here an algebraic analytic solution is obtained in bipolar cylindrical coordinates for Newtonian and power- law liquids. Dimensionless average velocity profiles around eccentric dies are provided to help plastic pipe engineers determine the needed eccentricity. In curved hose manufacture, the die centerpiece is made eccentric to cause curvature. Dimensionless radii of curvature are plotted to help curved hose manufacturers select proper die eccentricity.
