摘要:
Methods are disclosed which decrease the time between de-molding a lens and initiating a hard coating process. The de-molded lens at a de-mold temperature TM is transported away from a mold. A dip tank is maintained at a temperature TD, where TD is less than TM , wherein the dip tank includes a liquid including a primer or a hard coat solution. The lens is dipped into the dip tank wherein the lens has a temperature TL greater than TD, so that intermediate cooling, cleaning, destaticizing and delays associated therewith are avoided. Other methods eliminate many conventional process steps and may include drying raw material to decrease primer coating times and employing robotic systems for carrying out the methods.
