A method of injection molding uses different mold inserts, such as lead frames, to selectively control material flow in order to produce different parts in a common mold. One mold insert can have a different geometry than another mold insert so that molten material is either blocked or allowed to flow through corresponding portions of the mold inserts. By changing out the insert used for injection molding, insert-molded plastic parts produced in the mold can differ by at least one part feature.

Magnetic field generating unit is fixed to object that moves relative to magnetic field detecting means. Magnetic field generating unit has magnetic field generator, first support structure that is fixed to object and second support structure that is independent of first support structure. Second support structure is supported by first support structure and supports magnetic field generator. For example, second support structure is formed of a nonmagnetic material, and magnetic field generator is arranged away from first support structure.

The invention relates to an electrochemical system unit comprising a plurality of electrochemical cells that are arranged in layers side by side, each cell comprising an anode plate, a cathode plate and a sealing element, wherein the sealing element is designed to seal a space between the anode and cathode plate. Said system also comprises at least two electrochemical cells of the electrochemical system unit having different manufacturing types of the sealing elements.

The resin molded article is molded by using an electrode sheet as an insert in a state where one surface of the electrode sheet is closely attached to an inner surface which serves as the inner side of the operation surface. The electrode sheet is formed by using, as a base material, a thermoplastic synthetic resin sheet which outputs an electrical signal according to the amount of change of electrostatic capacitance generated by a contact operation with respect to the operation surface. At least a whole or a part of the inner surface is formed in a three-dimensionally curved surface, and a passage is formed in the electrode sheet so as to allow a molten resin following in through a gate formed in a die which comes into contact with the other surface of the electrode sheet during molding to pass toward one surface side of the electrode sheet.

A camera module, a molded circuit board assembly, a molded photosensitive assembly and manufacturing method thereof are disclosed. The camera module includes a molded base which is integrally formed with a circuit board through a molding process, wherein a photosensitive element may be electrically connected on the circuit board and at least a portion of a non-photosensitive area portion of the photosensitive element is also connected by the molded base through the molding process. A light window is formed in a central portion of the molded base to provide a light path for the photosensitive element, wherein a cross section of the light window is configured to have a trapezoidal or multi-step trapezoidal shape which has a size increasing from bottom to top to facilitate demoulding and avoiding stray lights.

A Magnetic Gear Modulator (MGM) of a Concentric Magnetic Gear (CMG) is manufactured by injection molding a modulator cage over angularly spaced apart MGM pole pieces made of a magnetically conducting material. The pole pieces are initially connected by a support ring, or held by a fixture. The modulator cage is preferably a thermally conductive strengthening fiber filled plastic, a carbon fiber plastic, a carbon fiber filled plastic material, a glass material, or a high performance composite plastic molding material. After molding, the outer and/or inner portions of the molding material, and support ring if present, are machined away preferably exposing both inner and outer faces of the pole pieces embedded in the modulator cage. An MGM made using injection molding over a connected support ring and pole pieces reduces cost, and a carbon fiber plastic modulator cage increases strength.

A fuel cell separator includes a separator main body having a first surface and a second surface, and a first seal member disposed on the first surface. When a region on the first surface of the separator main body corresponding to an electrode member disposed on the second surface is defined as a power generation region, and a region on the first surface of the separator main body corresponding to an in-cell seal member is defined as a seal region, a displacement/vibration reducing member made of polymer is disposed at a part of the seal region. The displacement/vibration reducing member includes multiple protrusions and a coupling portion. When viewed in plan view, an axis line connecting the centers of the figures of the adjacent protrusions does not coincide with a center line passing through the widthwise center of the coupling portion. The coupling portion has a gate cut mark.

In one example, an apparatus for jointing power cables includes a mold extending along a longitudinal axis, and having a feeding inlet and being made of two halves forming a longitudinal pass-through seat for receiving the cables. An extruder is connected to the feeding inlet. A heating system and a cooling system is associated with the mold. A measuring system for detecting temperature or pressure includes a plurality of probes for detecting temperature or pressure.

A polymeric structure includes a first polymeric component and a second polymeric component, the first polymeric component including a first mating surface and an opposing first free surface and the second polymeric component including a second mating surface and an opposing second free surface. The first polymeric component and the second polymeric component are positioned with the first mating surface facing the second mating surface. A charge of molten polymer is disposed between the first mating surface and the second mating surface. A compressive force is applied to the first free surface of the first polymeric component and to the second free surface of the second polymeric component in order to secure the first polymeric component to the second polymeric component in order to form the polymeric structure. The polymeric structure may be a construction mat.
