A biocompatible and/or food-safe tube assembly (1) is used to connect at least three tube connectors (A, B, C). A first tube section (2) serves to connect two (A, B) of the at least three tube connectors (A, B, C). A sec-ond tube section (3) opens into the first tube section (2) via an orifice (4) in a casing wall (5) of the first tube section (2). An orifice sealing body (8) delimits the orifice (4) to the inner lumen of the first tube section (2) and to the inner lumen of the second tube section (3). The first tube sec-tion 2 and the second tube section 3 are molded onto the orifice sealing body 8. A core (10) is used for this purpose. The result is a biocompatible and/or food-safe tube assembly that avoids manufacturing problems.

A method of manufacturing an optical connector ferrule includes a step of forming the optical connector ferrule by introducing a resin into a die. The optical connector ferrule includes one end surface and the other end surface, a pair of side surfaces, a front surface and a back surface, an introduction port that introduces a plurality of optical fibers in a bundle, a plurality of optical fiber holding holes that penetrate from the introduction port to the one end surface and hold the plurality of optical fibers, respectively, and a window hole that penetrates from the surface to the introduction port. A distance between a center of a gate and the front surface is less than a distance between the center of the gate and the back surface.

The invention relates to a method for producing a guiding rod for a pump for dispensing a fluid product. The rod includes a cylindrical body surmounted by a head. The method a plastic injection molding step to form the cylindrical rod. The method also includes a step of correcting the shape of an upper end of the rod so as to form the head by creating a shoulder at the level of the junction between the head of rod and body.

A respiratory nosepiece (10) and method of manufacturing the respiratory nosepiece, the respiratory nosepiece including a first nasal prong (110) with a first channel (112) extending there through, and a first side port (130) connectable to tubes (192, 194) having different first and second diameters. The first side port has a second channel (131) extending there through and in communication with the first channel. The second channel includes a first section (134) having the first diameter, a second section (136) having the second diameter, a first step (135) between the first and second sections, and a second step (137) between the second section and an end (133) of the second channel. The first and second channels are formed during injection molding by pins (412, 422, 431, 441) having flat pin-on-pin geometry to reduce resin flash within the channels.

An injection molding apparatus comprises a support base and a mold carrier removably mounted to the support base. The mold carrier includes a mounting plate with attachment features for engaging the support base. A mold with two mold plates is slidably mounted to the mounting 5 plate. A clamp is operable to move the plates between open and closed positions. In the closed position, the plates abut one another. In the open position, the plates are spaced apart for removing molded articles.

The disclosure is directed to an injection mold (1) comprising a mold insertframe (2) having several openings (3) extending in an axial direction (z). Each opening (3) accommodates a mold insert (4) encompassing a cavity (5), suitable to receive during operation melted plastic to form a plastic part. The several openings (3) with the mold inserts (4) are distributed around a center opening (6) of the mold insert frame (2). A nozzle head (7) is arranged in the center opening (6) of the mold insert frame (2). It comprises a primary melt channel (8), extending in the axial direction (z), and per cavity (5) a secondary melt channel (9) each interconnected at a dorsal end to the primary melt channel (8) and at a distal end to a cavity (5) by a nozzle tip (10) attached to the nozzle head (7). Each mold insert (4) comprises a first cooling channel (11) surrounding the cavity (5) and being in fluid communication with a first cooling circuit (12) across the mold insert frame (2).

A cavity plate assembly (400) for a preform mold (100), which includes a cavity plate (410) having an array of seats (412) and a corresponding array of cavity inserts (440) mounted to a front face (CVF) of the cavity plate (410) and in communication with a respective seat (412). Each cavity insert (440) includes a body (441) with a mounting face (441a) and a spigot (443) projecting from the mounting face (441a) and received in a respective seat (412) of the cavity plate (410) such that the mounting (441a) face abuts the front face (CVF) of the cavity plate (410). Each cavity insert (440) also includes a molding surface (448) along its length, at least two thirds of which extends beyond the cavity plate (410).

An injection molded thermoplastic preform for blow moulding to form a container, the preform base of a central part having a first, downwardly and radially inwardly tapering portion therebetween which increases in thickness from a radially outer end of the first tapering portion adjacent to the hollow transition portion to a radially inner end of the first tapering portion adjacent to the gate part and the middle part opposite the gate part can allow the injected resin to be urged back through the gate at the end of the injection moulding cycle at a lower fluid pressure in the vicinity of the gate which is associated with high resin temperatures. The technical effect achieved by the first tapering portion is that crystallinity in the gate area is minimized or eliminated, which avoids or minimizes partial blocking of the gate which would otherwise restrict the injected resin from being urged back through the gate at the end of the injection moulding cycle.
