Abstract
Described herein is method of co-molding an optical lens includes injection-molding a first layer, injection-molding a second layer against at least a portion of the molded first layer to form a co-molded blank, and forming the optical lens from the co-molded blank. Co-molding apparatuses for implementing this and other co-molding methods are also described.
Claims20
A co-molding apparatus comprising:
- a head having a first molding station and a second molding station,
- said first molding station comprising a first mold for forming a first molded layer of a co-molded part therein, said first mold defined by a first mold plate and a second mold plate,
- said second molding station comprising a second mold for forming a second molded layer of the co-molded part against at least a portion of the molded first layer;
- and
- an actuator coupled to said second mold plate, wherein said actuator is configured to rotate said second mold plate with the molded first layer coupled thereto, to position the molded first layer in said second molding station.
