Methods of fabricating a component, such as a cascade grid panel for a jet engine thrust reverser, having a plurality of cavities extending through the component, with each cavity having at least one surface with a complex contour, and related devices. A plurality of two or more mold inserts are stacked to form a mold insert stack, with the mold insert stack having a plurality of mold bosses formed by mold boss sets. The mold boss sets are each formed by a mold boss segment from each of the mold inserts. Further, the mold boss segments are affixed to respective baseplates so that the mold boss segments can be handled as a group and remain properly positioned relative to their neighboring mold boss segments.

The present application provides an apparatus and a method of welding a fabric material to a frame including for removable use in a door opening or a window opening. The method includes receiving the frame having an outer edge defining an interior space at a work surface. The fabric material is then extended across the frame, so that the fabric material to be welded to the frame rests on top and covers the interior space of the frame received at the work surface. An activated welding head is then moved across the work surface and the received frame, wherein the activated welding head is moved so as to trace proximate the frame along the outer edge of the frame, thereby adhering the fabric material to the frame at the outer edge.

According to examples, computer-readable instructions may cause a processor to obtain a digital model of a screen to be fabricated by a 3D fabrication system, the digital model of the screen including digital pores. The processor may obtain a digital model of a mold body on which the screen is to be removably mounted, the digital model of the mold body including a plurality of digital holes. In addition, the processor may, for a digital pore, determine a distance between the digital pore and a digital hole when the digital model of the screen is positioned on the digital model of the mold body. The processor may further determine whether the determined distance falls below a first threshold and based on a determination that the determined distance falls below the first threshold, cause a parameter of the digital pore to be modified in a first manner.

Electronic device housing structures and other structures may be formed from molded plastic. Plastic structures such as injection molding housing structures and other structures may be provided with openings. An opening may have sidewall surfaces. Machining operations and other techniques may be used in forming the openings. Openings may be processed to enhance resistance to stress-induced cracking of the plastic structures along the sidewall surfaces. Cracking resistance may be obtained by activating the surface using heat or laser treatment and by electroplating the activated surface to form a metal liner structure. Surface treatments using applied liquid chemicals or heat may form a treated layer on the surface of an opening with enhanced cracking resistance. A plastic sleeve or other insert may form a liner structure in an opening that resists cracking. Liner structures may also be formed by applying heat or light to a coating in an opening.

A mesh filter includes a filter unit connecting an outer peripheral surface of an inner cylinder and an inner peripheral surface of an outer cylinder. The inner cylinder, the outer cylinder, and the filter unit are integrally molded by injecting a thermoplastic resin into a cavity of a mold so as to have a one-piece construction. A portion of the filter unit other than a connecting portion between the inner cylinder and the outer cylinder has square-shaped openings formed by vertical ribs formed equidistantly so as to be orthogonal to an X-axis and parallel to a Y-axis, and lateral ribs formed equidistantly so as to be orthogonal to the vertical ribs and parallel with the X-axis. The vertical ribs and the lateral ribs have rib widths (L2, L3) in a range from 0.07 to 0.1 mm and thicknesses (L4, L5) along a center axis of the inner cylinder in a range from 0.2 to 0.4 mm.

The first (5) and the second portion (6) of the composite strip arrangement are disposed over a first surface (1a) of the composite structure (1), such that the major dimension of the core (3) is positioned transversal to said first surface (1 a). The at least one insert (2) is co-cured with the composite structure (1).

The invention relates to an attachment component (1) which comprises a body (2), the body (2) comprising attachment means intended for allowing the attachment component (1) to be assembled with a part including complementary attachment means, an insertion tip (6) arranged at one end of the body (2) so as to allow at least one portion of the body (2) to be inserted through a part made of composite material, an axial abutment (32) intended for halting the insertion of the body through the part made of composite material, and a breakable portion (8) inserted between the insertion tip (6) and said end of the body (2), the breakable portion (8) being configured to break when a predetermined force is applied to the insertion tip (6) with a view to detaching the insertion tip (6) from the body (2).

An improved method of manufacturing an equine protective covering includes applying a stamp comprising a profiled shape with a predetermined temperature and pressure to the interior side of the cushion assembly such that concurrently: the first synthetic fabric layer and the second neoprene layer are permanently bonded; the second neoprene layer is plastically deformed such that the profiled shape of the stamp is permanently transferred to the second neoprene layer; and the plastic deformation of the second neoprene layer is such that the perforations remain open.

According to some aspects, a method is provided of removing debris from a liquid photopolymer in an additive fabrication device. According to some embodiments, a mesh of solid material may be formed in an additive fabrication device from a liquid photopolymer, and particles of debris present in the liquid photopolymer may adhere to the mesh. The debris may thereby be removed from the liquid photopolymer by removing the mesh from the additive fabrication device. The mesh may then be discarded.

A method is provided for producing a component connection. The method includes the following steps: providing a first component, providing a first ball, pressing the first ball against the first component by a sonotrode, vibrating the first ball by the sonotrode such that material of the first ball and/or material of the first component melts, and the first ball is welded to the first component, providing a second ball, pressing the second ball against the first ball by the same sonotrode or another sonotrode, and vibrating the second ball by the same sonotrode or the other sonotrode such that material of the second ball and/or material of the first ball melts, and the second ball is welded to the first ball.
