A shaping machine includes a stationary first mold mounting plate, a second mold mounting plate movable with respect to the first mold mounting plate, a tubular snorkel fixedly secured to the second mold mounting plate, and an injection unit for plasticizing and injecting a molding material. An abutment is designed so that, in the opened condition of the closing unit, the injection unit can be braced against the abutment, and so that, in a closed condition of the closing unit, the injection unit is freed from the abutment by the force action of the snorkel on the injection unit.

Disclosed is a pierceable septum for use in drug reservoirs and infusion sets. The pierceable septum has an elastic core made from a core material and a surround made from a surrounding material. The surrounding material is more rigid than the core material. The elastic core is fully embedded in the surround.

A method for forming a part in an injection mold, includes: heating a molding material to a molding temperature; injecting the molding material through a gate and into a molding cavity of the injection molding apparatus of any of the preceding claims; pressing the stationary half and the moving half together to form the molding cavity between the resin mold surface and the insert molding surface; moving the movable mold insert, and thereby moving the insert molding surface and adjusting the molding cavity shape, the molding cavity depth, the molding cavity volume, or a combination comprising at least one of the foregoing along at least a portion of the molding cavity; cooling a surface of the molding cavity with the cooling system; separating the resin mold surface and the moving half mold surface; and ejecting the part from the injection molding apparatus.

The present invention relates to micro-/nanostructured compound-eye arrays and fabrication method thereof, and discloses a fabrication method and applications for the molded polymer parts with the micro-/nanostructured compound-eye arrays on their surfaces, which exhibit both hydrophobicity and light trapping. The fabrication method for the molded polymer parts with the micro-/nanostructured compound-eye arrays includes following steps. A flexible microlens array template is assembled; the flexible microlens array template is fixed on an injection mold cavity, and a polymer part with microlens arrays distributing on its surface is molded by using injection molding; the microlens arrays on the molded polymer part are imprinted onto the surface of an ultra-pure aluminum foil, nanopores are formed on its surface via anode oxidation, and so an aluminum template with negative micro-/nanostructured compound-eye arrays is fabricated; the aluminum template is fixed on an injection mold cavity, and a polymer part with micro-/nanostructured compound-eye arrays distributing on its surface is molded by using injection molding. The dual-level compound-eye arrays (orderly distributed convex semi-sphere microlens and densely distributed nanopillars) are developed on the surface of the molded polymer part, which exhibits both hydrophobicity and light trapping.

A mold for a plastic lens that arranges an insert member inside a cavity formed between a pair of halved molds, injects and fills molten raw material resin to mold a plastic lens having a predetermined shape, integrally with the insert member. The insert member is arranged on a molding surface on one of the halved molds, a notch to be engaged with a positioning tab formed at a periphery of the insert member is engraved on one parting surface of the halved mold, overlapping with a gate position. Positioning of the insert member is performed by engaging the positioning tab with the notch. With this configuration, in molding a plastic lens having an insert member by injection molding including insert molding, positioning of the insert member is performed at the gate position without deteriorating the quality of a molded product and without increasing the load of post-processing after molding.
