Abstract
A device and method for spin casting articles such as lenses employing a polymerization tube in conjunction with a plurality of molds such that the tube is adapted to accommodate the plurality of molds in an interference fitting and sliding relationship so that rotation of the polymerization tube will cause the molds to rotate at the same speed while maintaining the concentricity of the molds to the spinning axis of the tube to produce quality spun cast articles.
