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 polymeric device including: an elongated hollow tube having an outer surface; and a spiral fin wound around the outer surface of the hollow tube; wherein the hollow tube and the spiral fin are formed of a single unitary piece through a molding process. The polymeric device can further include a longitudinal projection projecting from the outer surface of the hollow tube, the longitudinal projection having a greater thickness than other portions of the hollow tube and the longitudinal projection extending at least a portion of a longitudinal length of the hollow tube.

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.

A plug-in connector produced by injection molding a plastic material and having an internal channel for a fluid and having three main sections situated axially one behind the other. The plug-in connector has a gate point on its outer circumference solely on one side and a mass distribution of the plastic material that is radially asymmetrical with respect to the circumference and which is present in at least one of the main sections of the shaped part. A method for the production of the plug-in connector is likewise disclosed.

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.

Provided is a method of manufacturing a sensor. The sensor has a casing having an opening portion, a clamp having a recessed part on its outer periphery and having one end inserted into the opening portion, and a sealing ring attached to the recessed part and disposed between the casing and the clamp. The method includes using a first divided mold to form a first component of the clamp, the first component including a main body portion and a first part located at one end side of the main body portion and forming a part of the recessed part. The first divided mold is divided so that a dividing surface intersects the main body portion and separates in an axial direction of the main body portion.

A water delivery pipe made from PVC or PVCO and having an inner surface which is rifled. The inner surface of the pipe preferably includes a graphene material. The pipe has improved anti-bacterial properties such that the formation of bacterial biofilms is eliminated or reduced.

Methods of making the pipe are also disclosed.

Injection mould for producing mouldings having a cavity plate with cavities and a core plate with cores. The cavity plate and the core plate are movable between a closed position, in which each core is respectively arranged in a cavity, and an open position, in which no core is arranged within a cavity. Each moulding space is assigned a neck-ring pair with two neck rings, and the neck-ring pair is arranged on the core plate and is movable between a holding position, in which neck rings of the neck-ring pair are in contact, and a releasing position, in which neck rings of the neck-ring pair are not in contact. To provide an injection mould with which mouldings can be produced and provided for further processing as efficiently as possible, the cores and the cavities are arranged on a curved path.

A pipe connector having a body with a tubular part to seal with a pipe. The tubular part has an outer face with a projecting feature to seal with the pipe. A collet is fixed to the body and spaced from the tubular part to form a cavity for the pipe. A locking cap is captive on and screwed onto collet to deflect the collet onto the pipe and the pipe onto the tubular part to seal between the body and the pipe. The collet has through slots at its distal end allowing the pipe to be visible when the connector is locked and unlocked. The inner diameter at an open end of the collet is optionally greater than the inner diameter of the distal part that receives the pipe. A method of forming the connector is also disclosed.

A thin-walled flexible package (1) is provided with a spout (6) comprising a connection portion (12) and a tube (18) having an outer surface (18e) and ending with an outlet mouth (20). A sacrificial closure (200) is applied to the spout (6) to close the outlet mouth (20). The sacrificial closure (200) comprises a skin (202) suitable for sealing engaging the outer surface (18e) of the tube (18) at a scaling region having a scaling distance (H) from the outlet mouth (20). On the outer surface (18e) of the tube (18) there is a circumferential dividing line (L2) having a division distance (H2) from the outlet mouth (20). The scaling distance (H) is less than the division distance (H2).
