A glass forming machine, a method for lubricating a baffle and a swabbing device for a glass forming machine is disclosed. The glass forming machine comprises a blank station with a blank mould for forming a parison from a gob of molten glass inside the blank mould. The glass forming machine further comprises a baffle for closing the blank mould. The glass forming machine further comprises a swabbing device which is configured to spray lubricant onto the baffle for lubricating the baffle. This enables a particularly high quality of the formed parisons and the corresponding glass containers.

The present disclosure relates to a method for producing an optical element (202), wherein a blank of transparent material is heated and/or provided and, after heating and/or after being provided between a first mold (UF) and at least one second mold (OF), is press molded to form the optical element (202), in particular on both sides, and is then sprayed with a surface treatment agent.

A molding tool made of carbon or graphite, namely a casting mold or a casting core for the processing of molten metal or to a molding tool for the processing of molten glass, such as for example a blow mold and a method for producing the molding tool.

A pair of moulds for moulding an optical component is disclosed. The pair of moulds includes a first mould having a first surface, and a second mould having a second surface. The first surface includes a moulding portion for moulding a first optical surface of the optical component, and an alignment portion for alignment with the second mould. The alignment portion extends around the moulding portion. The second surface includes a moulding portion for moulding a second, opposite optical surface of the optical component, and an alignment portion for alignment with the first mould via a contact with the alignment portion of the first surface. When the moulds are brought together, they self-align. A corresponding moulding apparatus and a method may use the mould pair to manufacture various optical components.

One exemplary embodiment of this disclosure relates to a transfer molding assembly. The assembly includes a die having a molding cavity interconnected with a reservoir. The assembly further includes a heater operable to heat the die, and a load plate configured to move under its own weight to transfer material from the reservoir into the molding cavity.

A nozzle deposits a filament of viscous, molten glass onto a print bed, while the print bed rotates about a vertical axis and translates in x, y, and z directions. The deposition is computer controlled, such that the resulting deposited filament forms a desired glass object that is solid after it anneals. One or more motors rotate the print bed such that the direction of deposition of the molten glass is constant relative to the nozzle, even though the print bed is translating in different directions relative to the nozzle. Keeping the direction of deposition constant relative to the nozzle tends to prevent the extruded filament of molten glass from experiencing large, changing, tensile and shear forces that would otherwise occur and that would otherwise damage the filament.

The present disclosure relates to a method for producing an optical element (202), wherein a blank of transparent material is heated and/or provided and, after heating and/or after being provided between a first mold (UF) and at least one second mold (OF), is press molded to form the optical element (202), in particular on both sides, and is then sprayed with a surface treatment agent.

The present invention relates to a container, which accommodates a drug and is sealed, includes a container stopper part including at least one filling groove formed in order to inject a drug, and a container body including an opening into which the container stopper part is inserted and which is sealed, wherein the filling groove is formed in an outer wall surface of the container stopper part in a longitudinal direction in which the container stopper part is inserted thereinto and forms a passage which is formed between the outer wall surface of the container stopper part and an inner wall surface of the container body and through which the drug is injectable.

An injection molding method includes the steps of:(A) preparing a molding unit and an injection unit, the molding unit including a first mold having a protruding portion, and a second mold having a movable post cooperating with an inner peripheral surface thereof to define a cavity; (B) moving the molds toward each other until the protruding portion cooperates with the second mold to define a forming space; (C) activating the injection unit for injecting the molten optical material into the forming space; (D) cooling the molding unit; and (E) moving the molds away from each other and subsequently activating the movable post to push a solidified optical material out of the forming space.

Proposed is a separable fireproof cover for a valve actuator, the cover including: a plurality of parts, wherein one of the plurality of parts includes: a heat-blocking fireproof glass window in a shape of a circular plate; and a solid fireproof agent provided around an edge of the heat-blocking fireproof glass window, and the one of the plurality of parts is injection-molded by injecting the heat-blocking fireproof glass window and a liquefied fireproof agent into a mold into which a zinc-coated mesh is provided, the liquefied fireproof agent being obtained by mixing epoxy-based Chartek A and Chartek B in a 2.44:1 weight ratio.
