Abstract
A method for forming a plastic prosthesis bearing, net-shape bearing or near net-shape bearing is provided. The method includes providing a cross-linked plastic resin preform in a volume sufficient to accommodate the bearing and molding the cross-linked preform. The molding is accomplished by applying heat and pressure to form the preform into a desired solid plastic shape. The heating and pressure is sufficient to melt the plastic resin so that the plastic resin flows under pressure and quench remaining free-radicals.
