A method for manufacturing a wheel, the method including a step of making a rim on a radially outer peripheral edge of a carrier core, during the step said carrier core, which extends from a radially inner wall forming a steering axis bore corresponding to the axis of rotation of the wheel, until the peripheral edge, is placed in a mold formed by at least one first portion and one second portion, then an injection material is injected by means of at least one injection nozzle so as to coat, by overmolding, at least partially said carrier core in order to form the rim, wherein after the injection of the injection material, the first portion of the mold and the second portion of the mold are brought closer to each other such that the injection material is compressed in the mold.

Disclosed herein, amongst other things, is, a stripper assembly operable to eject a molded article from a mold that includes slides that are movable laterally relative to each, a first split mold insert inter-connected to a first slide and a second split mold insert inter-connected to a second slide. The system being operable such that when the first and second slides are in the closed position, the first and second split mold inserts form at least a portion of the molding cavity; the system being operable such that such during operation of the injection molding system, the first split mold insert is movable relative to the respective first slide and the second split mold insert being movable relative to the second slide.

A drinking straw has an elongated body with a longitudinal flow channel. The user end of the body is closed and rounded for safety. A pair of lateral channels open onto the body adjacent the user end and provide fluid communication to the flow channel. The straw is injection molded, and a mold is provided which accommodates thermal expansion of a rod forming the flow channel. A pair of opposed cavity inserts form the lateral channels. To reduce bending stresses on the rod upon removal of the cavity inserts, one cavity insert is formed longer to the other. This longer cavity insert is removed prior to opening of the mold plates, and as such the straw and rod are supported against bending during this removal.

A mold, system and method for manufacturing a part includes injection molding a substrate in a single injection mold and optionally trimming the panel substrate. The substrate can have a first configuration or a second, different configuration. Trimming of the substrate can occur when the substrate has the first configuration to define an aperture in the substrate.

A manufacturing method of a resin container includes: a first injection molding process for injection-molding a first layer of a preform by using a first resin material, the preform having a bottomed cylindrical shape and including a groove that extends in an axis direction; a second injection molding process for injecting a second resin material into the groove of the first layer, the second resin material having a color that is different from a color of the first resin material, and laminating a second layer on an outer peripheral side or an inner peripheral side of the first layer; and a blow-molding process for blow-molding a preform that includes multiple layers and has been obtained in the second injection molding process in a state where residual heat at a time of injection molding is contained, and manufacturing the resin container having a vertical-striped color pattern formed by using the second layer.

This insert-molded filter is obtained by insert-molding a cylindrically-shaped mesh into a resin body. This insert-molded filter is provided with: a body which is equipped with a first annular part, a second annular part, and multiple columnar parts connected to the first and second annular parts, and which has multiple openings formed so as to be separated by the multiple columnar parts between the first and second annular parts; and a mesh which is integrally molded with the body so as to cover the multiple openings separated by the multiple columnar parts. The body is provided with a resin introduction part that is disposed outside of the mesh in the radial direction of the first annular part.

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 needle guard grip device may include a body extending from a first end to a second end along a central longitudinal axis of the body. The body may include a plurality of ribs extending perpendicularly to the central longitudinal axis. The plurality of ribs may include a first set of longitudinally spaced ribs disposed on a first side of the central longitudinal axis, and a second set of longitudinally spaced ribs disposed on a second side of the central longitudinal axis that is opposite of the first side. Moving along the central longitudinal axis, ribs of the first set of longitudinally spaced ribs may alternate with ribs of the second set of longitudinally spaced ribs.
