A soft-melted parison is disposed in molds forming a shape of a measurement pipeline portion 10, the parison is expanded by means of gas inflow, and blow molding is performed. The shapes of a pipe body 11, a fluid inlet portion 12, and a fluid outlet portion 13 are formed by an inner mold of the molds. Ultrasonic wave input-output portions 14a and 14b bulging outwards in a sealed manner are formed on both sides positioned in the oblique direction of the pipe body 11 with respect to a center line of the pipe body 11. Parts of the ultrasonic wave input-output portions 14a and 14b are wall surfaces 15a and 15b for attaching ultrasonic wave transmission-reception units. The measurement pipeline portion 10 is obtained by cutting end portions of the fluid inlet portion 12 and the fluid outlet portion 13 after the parison is solidified.

A method for manufacturing an angle-type air tool housing is provided. The angle-type air tool housing includes a hollow tube having a first end and a second end that are open and are mutually in communication, and an overall housing formed by injection molding and enveloping the hollow tube, and having an accommodating chamber adjacent to the first end, an air channel adjacent to the second end and in communication with the accommodating chamber through the hollow tube, and a pair of recesses exposing a part of the hollow tube. Accordingly, the angle-type air tool housing that is a formed integral with the hollow tube is formed so as to achieve effects of reduced costs and weight.

Methods and systems for manipulating surface topology of additively manufactured fluid interacting structures, such as additively manufactured heat exchangers or airfoils, and associated additively manufactured articles, are disclosed. In one aspect, an article which interacts with a fluid is imparted with surface topology features which affect performance parameters related to the fluid flow. The topological features may be sequenced, combined, intermixed, and functionally varied in size and form to locally manipulate and co-optimize multiple performance parameters at each or selectable differential lengths along a flow path. The co-optimization method may uniquely prioritize selectable performance parameters at different points along the flow path to improve or enhance overall system performance. Topological features may include design features such as dimples, fins, boundary layer disruptors, and biomimicry surface textures, and manufacturing artefacts such as surface roughness and subsurface porosity distribution and morphology.

Methods and devices for manufacturing plastic preforms and plastic containers are provided. Methods of manufacturing a plastic preform having an inner undercut include forming a preform of plastic in amorphous state and inserting a plug within the mouth of the preform. The plug includes an upper plug member and an expandable element, the expandable element having an initial outer diameter in plan view with the plug in an initial condition and a deployed outer diameter in plan view with the plug in a deployed condition. Methods further include deploying the plug to the deployed condition with the expandable element positioned to engage a side wall proximate the inner undercut and crystallizing the plastic of the preform along the finish portion.

A mold apparatus for molding a rotating member includes: a column mold portion including a first column molding hole extending in a first direction and configured to mold a column portion therein and a first blade molding groove formed as an intaglio on an inner circumferential surface of the first column molding hole to have a shape corresponding to a blade and configured to mold the blade therein, and an extraction guide configured to push a first end of the column portion in the first direction to thereby extract the column portion from the first column molding hole, at least a portion of the extraction guide being positioned inside the first column molding hole. The extraction guide is configured to press the column portion to thereby extract the column portion from the first column molding hole while the column portion rotates in an inclined direction of the blade.

A blow moulding machine for blow moulding a container having an integrally formed handle; said container blow moulded from a previously injection moulded preform; said preform comprising a body portion and said integrally formed handle; said machine including a preform loading station at which said preform is oriented by a preform orienting apparatus.

The invention relates to an injection molding device for manufacturing tubes having an internal thread, having a tool that forms an article cavity, having means for filling the article cavity with a thermoplastic molding compound, having an injection device for injecting a fluid toward a projectile to be driven through the article cavity, wherein the injection device comprises a projectile carrier having at least one injection nozzle and having at least one projectile receptacle for a projectile as a displacement member for the molding compound, wherein the projectile carrier at an end that is remote from the projectile receptacle is provided with a thread-bearing stamping core which is adjustable relative to the projectile carrier between a thread-forming first position and a demolded second position, wherein the stamping core in the thread-forming position plunges into the article cavity and seals the latter.

A protection tube with latch in which a latch that is formed engageable with an attachment hole of a panel is molded integral with a protection tube that receives an electric wire, and a manufacturing apparatus of the protection tube with latch. The protection tube with latch includes a latch to be engaged with the attachment hole of the panel having the electric wire wired therein disposed on an outer peripheral face of the protection tube that is formed tubular and receives the electric wire.

A blow molding machine for blow molding a container having an integrally formed handle; said container blow molded from a previously injection molded preform; said preform comprising a body portion and said integrally formed handle; said machine including a preform loading station at which said preform is oriented by a preform orienting apparatus.
