A molding device for producing a molded module. The molding device has one tool part and one further tool part, which together enclose a cavity. At least one of the tool parts has at least one dividing web arranged and configured to subdivide the cavity into at least a low-pressure sub-cavity and a high-pressure sub-cavity. The tool part has at least two feed channels, of which a low-pressure feed channel opens into the low-pressure sub-cavity and has a smaller cross-section at least over a longitudinal portion than a high-pressure feed channel opening into the high-pressure sub-cavity. The low-pressure feed channel is configured to become pressure-resistantly blocked through hardening of the molding compound once a predetermined time interval has elapsed or during the interval. The high-pressure feed channel is configured to conduct a molding pressure into the cavity for a longer time interval than the low-pressure feed channel.

A system or method of forming a handle portion of an oral care implement and a handle portion of an oral care implement formed thereby. The method may include providing a first mold that defines a first mold cavity having a shape that corresponds to the handle portion, injecting a first material into the first mold cavity via a first injection orifice with a first hot runner sub-system, and injecting a second material into the first mold cavity via a second injection orifice with a second hot runner sub-system. The second material is injected into the first material thereby forming the handle portion, with the second material forming a core component of the handle portion and the first material forming a shell component of the handle portion that surrounds the core component.

Plural ejector pins are made to project before a molten resin containing reinforcing fibers is injected into an inside of a cavity through pin point gates in a web forming portion in the inside of the cavity and at positions outside the pin point gates in a radial direction. The ejector pins are retracted from the inside of the cavity after a flow of the molten resin containing reinforcing fibers injected into the inside of the cavity through the pin point gates impinges on the ejector pins and is divided and before a tooth portion forming portion in the inside of the cavity is filled with the molten resin containing reinforcing fibers. Accordingly, weld lines which extend along the radial direction are formed at positions outside the ejector pins in the radial direction, and the molten resin is filled in portions formed after the ejector pins are retracted.

The present invention suppresses the formation of a pocket in a wall of a puncture route when a dull needle is moved forward along the puncture route. In order to achieve such aim, the invention provides a needle to be inserted into a puncture route extending from skin to a blood vessel under the skin to puncture the blood vessel, wherein: the needle is formed in a tubular shape and has an inclined end face at a tip of the needle, the inclined end face being inclined relative to an axis of the needle, a tip end of the inclined end face defining an unsharp edge; the needle has a flexibility of needle elastic modulus nE=1-900 Nmm as defined by an equation to be set forth below; a material of the needle is a resin; and the needle is manufactured by injection molding using a ring-shaped gate.

A strain gauge nozzle adapter that may be placed between a barrel end cap and a nozzle body of an injection molding system, the strain gauge nozzle adapter having a strain gauge pin that measures strain within the strain gauge nozzle adapter for use in approximating conditions within an injection molding system, such as pressure or the location of a melt flow front. The strain gauge nozzle adapter may include a plurality of strain gauge pins. An alternative material insert in the strain gauge nozzle adapter may surround a strain gauge pin to amplify meaningful measurements obtained by the strain gauge pin so that noise measurements do not compromise the accuracy of approximation of conditions within a mold.

Improved injection molding methods and molds, for forming TPU layers, especially thin TPU covers, into golf ball constructions, and having improved number, shape and placement of both the injection gates and the cold slugs within the mold in order to minimize/eliminate damage to dimples strategically positioned close to the parting line of a mold in order to maximize aerodynamic properties of the resulting golf ball.

The invention relates to an element of a vehicle luminous device, including an element made from a synthetic polymer material and includes an injection space which is formed by a primary space and a secondary space. The element further includes a material injection channel with at least two portions which extend in different directions. A first portion includes an injection location and a second portion is connected to the secondary space, and at least one angled portion with a variable angle connecting the at least two portions and including a protuberance.

A molding die for molding, on a surface of a plate-like base material, an endless-shaped gasket made of an elastic material includes a cavity which is formed on the opposing surface opposed to the surface of the base material and corresponds to the shape of the gasket, a gate for introducing a molding material which is cured to become an elastic material, a first intermediate portion connecting a gate opening and the cavity and a cross section along the base surface has an area equal to or larger than an opening area of the gate opening, a vent discharging gas unnecessary for molding, and a second intermediate portion connecting an opening on the cavity portion side of the vent extending along the base surface and the cavity and a cross section along the base surface has a cross-sectional area equal to or larger than an area of the gate opening.

An injection molded article is obtained by injection molding a molten resin into a mold. The injection molded article includes: a base as a thin plate-shaped member that is connected to a gate of the mold; and a plurality of protrusions each integrally molded on the base and having a thickness greater than a plate thickness of the base. The plurality of protrusions have holes each extending through the base, and the holes in the respective protrusions are connected through another component to form a flow channel. A processed region processed to have a surface roughness greater than a surface roughness of a mirror surface region including a region between the holes on the base is formed in a projected region where a region having a predetermined thickness value is projected on the base.

A compression collar is manufactured for use in reinforcing an interference fit between an end of a pipe and a fitting. A precursor form is injection molded using a cold-expansion material. The precursor form has a tubular body with an initially closed axial end and a bore that is initially blind formed in the other axial end. Material is removed from the initially closed axial end of the tubular body of the precursor form to form an opening in the initially closed axial end that connects to the bore thereby forming the compression collar. The opening has an inner periphery with a profile in axial cross section that is different than any profile in axial cross section of an inner periphery of the bore. The collar formed may lack knitlines and may include tabs formed during the removal step which help to position the collar on a pipe.
