REUSABLE MOLD FOR INJECTION MOLDING AND MOLDING METHOD
A reusable mold for injection molding and molding method includes a reusable mold member, a mold cavity defined in the mold member, and at least one heat sink recess defined in the mold member for accommodating a heat sink material therein for rapidly removing heat from the mold cavity when the mold member is used to injection mold a molded part. The reusable mold injection molds a molded part and rapidly removes heat from the mold cavity via a heat sink material accommodated in the at least one heat sink recess.
Techniques for casting from additively fabricated molds and related systems and methods
According to some aspects, a method is provided of casting an object from a mold, the method comprising obtaining a mold comprising a hollow shell of rigid material, the material comprising a thermoset polymer having a plurality of pores formed therein, providing a metal and/or ceramic slurry into an interior of the mold, exposing at least part of the mold to a low pressure environment so that a net flow of gas is produced from the interior of the mold into the low pressure environment. According to some aspects, a method of forming a porous mold is provided. According to some aspects, a photocurable liquid composition is provided, comprising a liquid photopolymer resin, particles of a solid material, in an amount between 30% and 60% by volume of the composition, and a water-soluble liquid.
MOLDING DIE, MOLDING APPARATUS, MOLDING METHOD, AND MANUFACTURING METHOD FOR RESIN PRODUCT
A molding die includes a resistance heating element included in a surface portion of the molding die and configured to heat a molding surface by generating heat, and a heat insulator provided further inside the molding die than the resistance heating element and configured to restrain the heat of the surface portion of the molding die from being transmitted to an inside of the molding die. The surface portion of the molding die includes the molding surface.

Nanostructures from laser-ablated nanohole templates
Solution casting a nanostructure. Preparing a template by ablating nanoholes in a substrate using single-femtosecond laser machining. Replicating the nanoholes by applying a solution of a polymer and a solvent into the template. After the solvent has substantially dissipated, removing the replica from the substrate.

COMPOSITE STRUCTURES, FORMING APPARATUSES AND RELATED SYSTEMS AND METHODS
Apparatuses for forming a composite structure are configured to provide a tension at least partially along at least one ply of material as the at least one ply of material is supplied from a material feed assembly to a tool.
METHOD FOR PRODUCING A PACKAGED PORTION OF A FOOD PRODUCT AND PORTION PRODUCED BY SAID METHOD
This method for producing a packaged food product portion includes the following steps: providing a cup defining an inner area for receiving the food product; cold pouring, at a temperature below 50 C., the food product into the receiving area of the cup; covering the food product using a thermally insulating lid arranged such that thermally conducting flaps of the cup extend toward the outside of the lid after the covering step; folding the flaps on an outer face of the lid opposite the receiving area; and heat-sealing the flaps on the outer face.
