The molding process involves injecting liquid polymer into a mold, which rotates as the plastic polymerizes. As the plastic polymerizes, the centripetal force shapes and shapes the lens. The molded contacts are moist throughout the process. Following the molding process, the polymer disk is cut using an industrial diamond and polished with an abrasive. This procedure shapes both soft and strong lenses. After the disk has been shaped, it can be hydrated once again.
