The present document discloses a tool or tool part for use in a process of molding a product from a pulp slurry. The tool or tool part comprises a self-supporting tool wall portion having a product face, for contacting the product, and a back face on the other side of the wall relative to the product face. The tool wall portion presenting pores, which are provided by a plurality of channels extending through the tool wall portion, from the product face to the back face. The channels are straight or curved with no more than one point of inflection.

This disclosure describes systems and methods for creating porous molds using additive manufacturing processes such as three-dimensional (3D) printing. At a high level, it has been found that creating a generally porous mold, or a mold with porous regions or zones, can improve the performance of the mold and the quality of the parts created therefrom. It has further been determined that porous molds can be created using additive manufacturing techniques through manipulation of mold manufacturing parameters such as, but not limited to, layer thickness, number of perimeter layers, fill pattern, and fill density. Through variation of these manufacturing parameters, the porosity of a mold created by an additive manufacturing device, e.g., a 3D printer, can be tailored for use with molded fiber.

The present invention relates to a material system for 3D printing, to a 3D printing process using a lignin-containing component or derivatives thereof or modified lignins, to soluble moldings that are produced by a powder-based additive layer manufacturing process and to the use of the moldings.

Provided is a method for processing and manufacturing a metal structural material by knitting metal wires into metal screen mesh strips, tightly coiling the metal screen mesh strips to form a coiled blank body which is coated layer-by-layer and in which an outer-layer material tightly covers an inner-layer material; sintering the coiled blank body; reducing gaps within the coiled blank body material by plastic processing to reach a porosity that fulfills requirements, and manufacturing mechanical structural parts therefrom.

A moulding installation and method for moulding food products from a pumpable foodstuff mass are described. A revolving mould drum is provided with multiple mould cavities and a mass feed member is arranged at a fill position to transfer foodstuff mass into passing mould cavities. The foodstuff mass forms a food product in the mould cavity. A pressurized air food product ejection system includes air ducts in the mould drum that extend to the cavities and at least a portion of the surface delimiting a mould cavity is air permeable. The ejection system further includes a pressurized air source to feed pressurized air at a regulated ejection air pressure thereof to the air ducts. A controller is adapted to input at least one target parameter related to filling of the mould cavities with the foodstuff mass via the mouth of the mass feed member. The controller is adapted to automatically set an ejection air pressure by the pressurized air source on the basis of the inputted target parameter.

A system for thermoforming an object is provided. The system includes a mold and a pressure-box. The mold has a surface that defines a shape of the object and includes two or more portions of differing porosities. The pressure-box is operative to generate a pressure differential across the surface. The two or more portions apply the pressure differential at different loads, based at least in part on the differing porosities, to a material disposed onto the surface so as to form the object by deforming the material into the shape.

A mold for encapsulating an electrical component. The mold includes an encapsulation chamber and an air inlet. The encapsulation chamber is defined by a housing, an open top, and a solid bottom. The housing includes a solid outer wall, a permeable inner wall, and an air chamber between the solid outer wall and the inner wall. The air inlet is configured to introduce a gas into the air chamber. The encapsulation chamber is sized and shaped to receive the electrical component while leaving a gap for the introduction of encapsulant around the electrical component. The encapsulant may be silicone rubber. To remove an encapsulated electrical component, pressurized air may be introduced through the air inlet into the air chamber, passing through the permeable inner wall, separating the outer surface of the encapsulant from the housing, and allowing the combination casting to be removed from the mold.

An injection molding apparatus includes a mold, an injection device, a porous structure, and a gas-driven unit. The mold has a mold cavity. The injection device is adapted to inject a material into the mold cavity so that the material is formed into a forming article. The porous structure is disposed on an inner surface of the mold cavity and corresponds to a non-appearance surface of the forming article. The gas-driven unit is connected to the mold and is adapted to drive a gas to flow into or flow out of the mold cavity through the porous structure. In addition, an injection molding method is also provided.

A transdermal drug delivery patch includes a flexible base layer, and a plurality of microneedles disposed at one surface of the base layer and including a biodegradable polymer and a drug. Each of a plurality of microneedles is formed as a star-shaped pyramid including a plurality of protrusions extending in a radial direction, and a concave shape is formed between two protrusions adjacent along a circumferential direction among a plurality of protrusions.
