In an example method of forming a waveguide film, a photocurable material is dispensed into a space between a first mold portion and a second mold portion opposite the first mold portion. Further, a relative separation between a surface of the first mold portion with respect to a surface of the second mold portion opposing the surface of the first mold portion is adjusted. The photocurable material in the space is irradiated with radiation suitable for photocuring the photocurable material to form a cured waveguide film. Concurrent to irradiating the photocurable material, the relative separation between the surface of the first mold portion and the surface of the second mold portion is varied and/or an intensity of the radiation irradiating the photocurable material is varied.

A molding apparatus includes a plurality of deep-draw compression molds. Each of the molds includes a mold cavity and an associated mold core. A rotating support structure operatively supports the mold cavities and the mold cores relative to each other. The molds open and close as they travel around a closed path defined by the support structure. A mold material discharge mechanism deposits a predetermined amount of mold material in each of the molds. A heat source superheats the molds, and a mold closing mechanism closes the superheated molds, compressing the mold material between the mold cavities and the mold cores to form a deep-draw component A coolant source rapidly and actively cools the molds, and a mold opening mechanism opens the cooled molds. An ejector is disposed to eject the deep draw components from the molds. A method of molding deep-draw components is also disclosed. The system and method of the present invention facilitate compression molding of deep-draw components.

A tooling system may include an outer mold line (OML) tool and one or more inner mold line (IML) tools. The OML tool may have an OML tool surface. Each one of the IML tools may have an IML tool surface and may be receivable within the OML tool 202. Each IML tool may be formed of expandable material. Each IML tool may apply an internal compaction pressure to a composite assembly positioned between the OML tool surface and the IML tool surface when the expandable material is heated.

An optical element includes a base having a curved depression formed in a front surface thereof and a formed layer arranged on the base. The formed layer includes a main part in the depression as viewed from a depth direction of the depression and an overhang on the front surface of the base while connecting to the main part. An opposite surface of the main part to a surface thereof on a side of an inner surface of the depression is formed like a concave curve that is concave in a same direction as the inner surface of the depression. A predetermined surface of the main part that is opposed to the inner surface of the depression is provided with an optical function part.

A forming mold for forming a prism by press molding includes a first mold, a second mold, and a third mold. The second mold includes a surface configured to form a base surface of a non-optical surface and is configured to define, together with the first mold, a space in which a material is disposed. The third mold is slidable with respect to the second mold so as to project toward the space with respect to the second mold and is configured to form a recess portion recessed with respect to the base surface.

Devices, methods, and mold apparatuses for forming devices facilitate consumption of a plurality of liquids by a user, such as a first liquid followed by a second liquid. In some cases, the first liquid is a relatively harsh liquid and the second liquid is a relatively mild liquid.
