The apparatus has a bending/cooling station mounted on a base. A tube clamping assembly is mounted on the base, movable towards and away from the bending/cooling station and including a tube clamping assembly and a tube rotation assembly. A tube heating assembly is mounted for movement between the bending/cooling station and the tube clamping assembly. Servomotors move the tube clamping assembly and the tube heating assembly, rotate the tube clamping assembly, and actuate bending at the bending/cooling station. The apparatus is controlled by PLC or PC-based programs, which effect movement via servomotors and control other parameters such as heating and cooling times and temperatures. Bending and cooling the tube at a first bend location, and heating the next desired bend location, take place in overlapping time windows, before advancing the tube to position the next desired bend location of the tube at the bending/cooling station.

A method of making a 3D tube and the 3D tube made thereby. The method comprises: inserting a deflated pre-formed bladder into the 3D tube; and inflating the pre-formed bladder to deform the 3D tube and make the 3D tube have a substantially similar shape as that of the pre-formed bladder inflated.

A pre-curved catheter tube of a catheter assembly or other elongate medical device and methods for forming such a device using a heating procedure is disclosed. Pre-curving of the catheter tube is desirable to impart to the catheter assembly a desired positional configuration when the catheter assembly is inserted into a patient. The heating procedure may include heat sterilization procedures commonly used to sterilize medical devices prior to use. One method for curving a catheter tube of a catheter assembly includes constraining the catheter tube into a curved configuration using the tube constraint, heating the catheter tube in the curved configuration for a predetermined time at a predetermined temperature, and releasing the catheter tube from the tube constraint after the heating is complete.

Curved heat shrink tubing and methods of making the same are described herein. An example method includes inserting heat shrink tubing into a tube, curving the tube, and deforming the heat shrink tubing, inside of the tube, to have a curved shape along a length of the heat shrink tubing where a first length of the heat shrink tubing along an outer radius of the curved shape is longer than a second length of the heat shrink tubing along an inner radius of the curved shape.

There is provided a hydrogen supply piping for supplying hydrogen to a fuel cell, the hydrogen supply piping includes a flow path pipe member through which the hydrogen flows, and a coating member having a tube shape for covering an outer surface of the flow path pipe member. The coating member is divided into a plurality of divided pieces in pipe axis directions of the hydrogen supply piping. The divided pieces are disposed in the pipe axis directions so that an end of one of the divided pieces overlaps with an end of the adjacent divided piece. The divided pieces are wrapped tightly around an outer surface of the flow path pipe member by thermal contraction.

A method of manufacturing a fluid impermeable rigid composite pipe (10) or hollow tube comprising the steps of:a. providing a supporting mandrel (15) that is shaped to define a bore of the pipe (10); b. laying onto the outer circumferential surface of the mandrel (10) one or more first tapes (11) made of a thermoplastic material thereby to create a first region (11) that is predominantly thermoplastic material adjacent the bore of the pipe (10); c. providing a plurality of tows (14) that comprise co-mingled reinforcing fibers and thermoplastic filaments; d. weaving a plurality of the tows (14) to form one or more circular braids (13) and laying down the one or more of the circular braids (13) on to the first layer (11): to form a second region (12); e. applying to the outer surface of the second region (12) a heat-shrinkable layer (13); f. heating the product of steps (b) to (e) on the mandrel (15) to a first temperature at which the thermoplastic materials of the one or more tapes 11 and the tows 14 melt and the heat-shrinkable layer 13 shrinks radially inwards to consolidate the melted thermoplastic material to form a thermoplastic matrix in which the reinforcing fibers are embedded and a fluid impermeable thermoplastic rich region (11) is formed at the bore of the pipe (10); and, g. allowing the pipe (10) to cool to form a self supporting pipe (10).

A pre-curved catheter tube of a catheter assembly or other elongate medical device and methods for forming such a device using a heating procedure is disclosed. Pre-curving of the catheter tube is desirable to impart to the catheter assembly a desired positional configuration when the catheter assembly is inserted into a patient. The heating procedure may include heat sterilization procedures commonly used to sterilize medical devices prior to use. In one embodiment, therefore, a catheter assembly is disclosed, comprising an elongate catheter tube defining at least one lumen, and a tube constraint. The tube constraint is included with the catheter assembly and is configured to temporarily constrain the catheter tube in a curved configuration during a heating procedure of the catheter assembly so as to permanently form the catheter tube in the curved configuration after the heating procedure is complete and the catheter tube is released from the tube constraint.

A weather strip including a bottom wall, a first lateral wall and a second lateral wall and in which an angle between the bottom wall and the first lateral wall is constant and an angle between the bottom wall and the second lateral wall is partially varied in a longitudinal direction is manufactured. The method includes: a first step of pre-forming the angle of the first lateral wall and the angle of the second lateral wall to be constant and equal to or larger than final maximum angles; a second step of regulating a boundary between the bottom wall and the second lateral wall from moving toward the first lateral wall by a regulating member; a third step of partially varying the angle of the second lateral wall by a movable roller; and a fourth step of forming the angle of the first lateral wall by a fine-movable roller.

The present disclosure is directed to a method of forming a composite component. The method includes laying one or more layers of uncured composite material onto a mandrel. The mandrel which includes a plurality of conductive media dispersed in a thermoplastic material. An electric current is supplied to the mandrel to resistively heat the one or more layers of uncured composite material to a temperature sufficient to cure the one or more layers of uncured composite material to form a cured composite component. The mandrel is removed from the cured composite component.

A component for a fuel injection system, in particular a high-pressure fuel injection system, includes a base body which is implemented in a tube-shaped manner at least sectionally. A tubular section of the base body is implemented having a longitudinal bending along a longitudinal axis of the tubular section which perpendicularly intersects the cross sections of the tubular section. At the longitudinal bending of the tubular section, the base body is implemented in such way that an ovality of the cross sections of the tubular section is reduced and/or smaller than 8% at the longitudinal bending.
