A contact lens production line pallet system transports contact lens mold materials throughout a facility for producing ophthalmic lenses. Specifically, the contact lens production line pallet system includes a pallet for carrying one or more contact lens mold assemblies throughout a contact lens production line, the pallet having one or more first recesses formed in a surface thereof for receiving either a first mold half or a complementary second mold half, the first and second mold halves when placed together constitute an individual contact lens mold assembly. A conveyor device for transporting the pallet from station to station throughout the production line facility is provided, as is a locating device formed in the pallet surface for enabling precise positioning of the pallet at one or more manufacturing stations in the production line facility.
