A mandrel has an outer peripheral member that shapes an outer peripheral surface of a mandrel, and a regulation member that regulates movement of the outer peripheral surface toward the radially inner side. A manufacturing device for a tubular member includes a radial movement mechanism that deforms the outer peripheral surface by actuating the regulation member into the outer peripheral surface in a winding shape and the outer peripheral surface in a separable shape, the separable shape being obtained by moving the outer peripheral surface in the winding shape toward the radially inner side and allowing the mandrel and the tubular member to be separated in the axial direction of the mandrel.

An injection mold (1) for the manufacturing of at least one tubular plastic part comprising a first mold half (2) comprising a first mold plate (3) and a second mold half (4) comprising a second mold plate (5) being arranged displaceable with respect to each other in an axial direction (Z) between an open position and a closed position. The injection mold further comprises at least one core (6) protruding from the first mold plate (3) and the second mold plate (4) comprising at least one cavity (7) suitable to receive the core (6) of the first mold half (2) to form a molding cavity (8) in the closed position of the injection mold (1) for receiving molten plastic material therein to form the tubular plastic part. A bushing (9) is advantageously arranged in the second mold half (4) adjacent to a dorsal end (10) of the cavity (7) at least partially displaceable with respect to the second mold plate (4), said bushing (9) comprising a bore (11) in a closed position of the injection mold (1) suitable to receive a tip (12) of the core (6).

The invention embodies an apparatus for producing resin tubes, the apparatus having a hollow supporting structure, wherein an endless carrier strip is windable around the outside of the supporting structure in a plurality of adjacent windings to form a mould.

A method for producing a channel-shaped hollow profile component from a nonwoven material includes providing first and second nonwoven material layers arranging the first and second nonwoven material layers in a mold tool having first and second mold tool halves and a core body wherein a formation of the first and second nonwoven material layers and the core body is arranged between the first and second mold tool halves, and wherein the core body is arranged between the first and second nonwoven material layers in the formation, and simultaneously forming the first and second nonwoven material layers in the mold tool to form a first nonwoven partial shell and a second nonwoven partial shell.

Provided is a production apparatus capable of producing a flexible tube whose hardness is naturally varied along the length direction thereof. This mixing valve includes: a first valve configured to distribute a first resin to a resin supply path and a resin discharge path; and a second valve configured to distribute a second resin to the resin supply path and the resin discharge path. In the mixing valve, the mixing proportion between the first resin and the second resin is increased or decreased in association with molding of the flexible tube, by changing a distribution ratio of the first resin in the first valve and a distribution ratio of the second resin in the second valve while keeping constant the total of the supply mounts of the first resin and the second resin supplied to a die.

A thermoplastic product includes a fabric-based reinforcing sheet and a polymerized thermoplastic material. The fabric-based reinforcing sheet is wound about a mandrel to form a plurality of layers having a cross-sectional shape that corresponds to the mandrel. The fabric-based reinforcing sheet includes a plurality of fiber bundles, which may have a bidirectional orientation or configuration. A polymerized thermoplastic material is disposed within each layer of the fabric-based reinforcing sheet. The polymerized thermoplastic material bonds each layer of the fabric-based reinforcing sheet to an adjacent layer.

Provided is a mesh-patterned resin molded product (10) used for encasing and protecting a hollow piping member provided in a vehicle or a small ship. The mesh-patterned resin molded product (10), in a case of an ordinary state where no load is applied to the mesh-patterned resin molded product (10), includes a plurality of first resin wired portions (11) that extend parallel to each other, and a plurality of second resin wired portions (12) that extend parallel to each other in a direction respectively intersecting the first resin wired portions (11). Each of the first resin wired portions (11) and each of the second resin wired portions (12) are joined to each other on a joint portion (13) positioned at a mutual intersection portion. At the intersection portion, a direction passing through both axial centers of the first resin wired portion (11) and the second resin wired portion (12) and being orthogonal to both the axial centers is set as an orthographic projection direction P. When the first resin wired portion (11) and the second resin wired portion (12) are viewed in the orthographic projection direction P, a second surface area that is a surface area of the joint portion (13) between the first resin wired portion (11) and the second resin wired portion (12) is smaller than a first surface area that is an overlapping surface area between the first resin wired portion (11) and the second resin wired portion (12). The plurality of first resin wired portions (11) and the plurality of second resin wired portions (12) are formed of a material including a thermoplastic resin.

A tubing system with a coupler join positioned between and joining tubing segments. The coupler join is formed to reduce dead legs and hold up volumes within, and/or to reduce materials used to form, and/or to simplify the manufacturing process of the tubing system. The coupler join may be sized, shaped, configured, and/or dimensioned to join tubing segments, such as pre-formed tubing segments, in a streamlined configuration, such as to substantially correspond with the outer and inner diameters of the tubing segments. The tubing system and coupler join may be formed with a mold configured to form a coupler join securely coupling spaced apart ends of tubing segments to be joined together in a configuration which reduces dead legs and hold up volumes within the resulting tubing system.
