A method that combines injection molding and extrusion is disclosed. First, a molten material is injected into a mold via an injection gate, the mold comprising a first portion and a second portion. Next, additional molten material is injected via the injection gate and pushed through an extrusion die located in the first portion of the mold and the second portion is separated from the first portion. In embodiments, the second portion is separated from the first portion before the additional material is injected. In other embodiments, the second portion is separated from the first portion simultaneously with the additional material being injected. The method may be used to produce longer and thinner parts with detailed features, such as catheters.

A resin member including an annular portion that defines a through hole with a circular cross section, and made of a resin containing reinforcing fibers, where the resin member has at least one gate trace; a weld portion is formed in the annular portion; and in a case where a polished surface along a perpendicular-to-axial direction perpendicular to a central axis of the through hole is formed in the annular portion, a sum of valley widths at half-value Txxh in a fiber orientation tensor waveform is 1.20 mm or more.

A blower which uses a rotation prevention member in which a rotating shaft with circular cross section is press-fitted is disclosed. The blower includes a scroll housing, a resin-made stator which is press-fitted on a rotating shaft with circular cross section, and a centrifugal fan which has a boss inserted on the stator, a cone extending from the boss, and blades extending from the cone, in which the stator and boss are a tubular members. A stator engagement part is formed in a stator outer circumferential face. The stator has a first weld face which extends substantially perpendicular to an axial direction of the rotating shaft, and second and third weld faces which are arranged to extend in the axial direction. A boss engagement part is formed in an inner circumferential face of a boss through hole and engages with the stator.

An injection molding method for a resin molded product includes a first molding step of molding an intermediate molded body with first and second main molds and a first slide mold that is closed in an axial direction of the first and second main molds. The injection molding method for the resin molded product further includes a detachment step of detaching the first slide mold from the intermediate molder body and a second molding step of molding a second annular wall portion on the intermediate molded body using a second slide mold that is closed along the axial direction against a tube end surface of the intermediate molded body and first and second core molds that is closed against the intermediate molded body in a direction orthogonal to the axis.

The disclosure relates to a plastic faucet body and a molding tool. The faucet body includes a left water inlet pipe and a right water inlet pipe, wherein a left valve seat installation recess is formed in the left water inlet pipe and a right valve seat installation recess is formed in the right water inlet pipe. A connecting cross-beam is disposed between the left water inlet pipe and the right water inlet pipe, wherein the connecting cross-beam is provided with a water outlet and a middle water channel is formed within the connecting cross-beam.
