A device (1) for the extrusion of filaments (2) comprising a plurality of extrusion capillaries (3) arranged in at least two consecutive rows and having extrusion openings (4) for extruding a spinning solution, whereby the filaments (2) are formed, and a plurality of components (7, 8, 10) for the generation of a gas stream for producing a gas stream oriented essentially in the direction of the extrusion of the filaments (2) at least in the area of the extrusion openings (4), wherein the extrusion capillaries (3) are arranged in extrusion columns (6) which protrude from a base plate (5) and are formed in one piece with said base plate (5).

Disclosed is a manufacturing method of a sheet molded article, including the steps of: thermoforming a molding sheet with a first mold, thereby molding a molded article including a body portion provided with a shape transferred from the first mold, and a peripheral edge portion surrounding the body portion; and removing the molded article from the first mold, and inverting the body portion front-to-back.

A forming tool is used, which has a tool trough arranged in a stationary manner and a pressure bell, which can be lowered onto and lifted away from the tool trough. An arrangement is created in which a single- or multi-layer, initially flat, flexible laminate separates the trough interior from the pressure-bell interior in a pressure tight manner. A table, on which the 3-D substrate to be coated is located, assumes a lowered position within the trough interior; there is a considerable, free intermediate space (between the laminate and the 3-D substrate. A radiant-heater assembly is inserted into said intermediate space. The radiant-heater assembly has a carrier, on the top side of which radiant heaters that can be activated are attached and on the bottom side of which radiant heaters that can be activated are attached.

A formed film includes a first surface generally located in a first plane, a second surface generally located in a second plane parallel to and spaced from the first plane, and a third surface generally located in a third plane parallel to and spaced from the first plane and the second plane, in between the first plane and the second plane. A porous structure extends between the second surface and the third surface. A plurality of raised areas have sidewalls that extend between the first surface and the third surface, and top portions that define the first surface. The plurality of sidewalls, the porous structure, and the first plane define a plurality of gathering volumes.

Provided is a molded article comprising an aliphatic polyester. The aliphatic polyester is at least one selected from the group consisting of polyglycolic acid and a copolymer of a glycolic acid monomer and a monomer other than the glycolic acid monomer. The molded article has a uniaxial compressive strength at a temperature of 23 C. of greater than 250 MPa and not greater than 350 MPa.

A nozzle and system for hydraulic blow molding of a plastic container from a preform. The nozzle includes a nozzle body having a main bore extending therethrough and a seal pin received in the main bore and moveable between a closed position and an opened position. The seal pin include a central bore extending from an entrance orifice to an exit orifice, with the entrance orifice opening into the main bore of the nozzle body.

An apparatus for transforming a pre-form into a container filled with liquid filling-material includes a feed line, a high-pressure source, a removal line, and a molding station having a mold, a mold space, and a mold head that permits liquid filling-material to be introduced into the pre-form under a filling pressure sufficient to transform the pre-form into a container and to seal against an opening of the pre-form as liquid filling-material flows through the feed line. The high-pressure source is in fluid communication with the liquid filling-material in the container such that exposure of the liquid filling-material to gas pressure in excess of the filling pressure pushes a pre-determined volume of the liquid filling-material out of the container, thereby forming a headspace in the container.

A thermoforming system and related methods for manufacturing thermoplastic parts, such as interior panels for aircraft, may include a roll-to-roll operation and a forming press having at least one selectively rotatable tool. The rotatable tool, which may include a mold and/or a die, may be multifaceted, such that different faces of the tool have different mold arrangements for different forming characteristics.

The disclosure relates to forming shaped thermoplastic articles having smooth peripheries. Many thermoplastic articles have sharp edges formed upon molding or cutting the article from a feedstock sheet. Such sharp edges can damage thin plastic films or flesh which they contact, and smoothing the edges is desirable. Described herein are methods of forming a smooth periphery for such sharp-edged articles by rolling over the sharp edge. The smoothing operation is performed by forming a deflectable flange including a bend region separated from the potentially sharp peripheral edge by a spacer, deflecting a portion of the deflectable flange, and softening at least one bent portion of the deflectable flange to yield a smooth periphery upon cooling. A liner sheet may be attached to the feedstock sheet prior to, during, or after forming and can be peelable therefrom.

A composite molded article is obtained by laminating (A) a fiber-reinforced resin molded article comprising a fiber-reinforced resin having a polyamide-based resin as a matrix resin, (B) a molded article comprising a polyolefin-based resin containing an epoxy group and/or a glycidyl group, and (C) a molded article having at least one selected from a polyester-based resin, a polyethylene-based resin and a polyarylene sulfide-based resin as a matrix resin, in this order, and a method produces the same.
