The invention relates to a method for producing primary packaging having an integrated septum characterised by: a) providing a septum, b) providing an injection-molding die having two die halves, c) positioning the septum in the injection-molding die, d) moving the two die halves of the injection-molding die to form a cavity corresponding to the shape of the primary packaging to be produced, e) injecting a material into the cavity via an injection opening, where the two die halves of the injection-molding die pretensioningly holding the septum, and a rim of the septum is overmolded by the material, f) cooling the injected material while maintaining a holding pressure, g) moving the two die halves of the injection-molding die such that the produced primary packaging means having the integrated septum can be removed from the injection-molding die, and h) removing the produced primary packaging having the integrated septum from the injection-molding die.

Provided is a rotation detection sensor and a resin molding die for the sensor, with which manufacturing cost can be readily reduced. The sensor includes an assembly type sensor body having a sensor element and a cable electrically connected to the sensor element. A curved portion is formed at a portion of the cable extending from the sensor body. There is provided a resin sheath portion molded to sheath a portion of the sensor body and the curved portion integrally with resin.

A unit cell injection mold for fabricating a unit cell of a fuel cell, in which an integrated frame of the unit cell formed by injecting a polymer resin onto an insert, in which a membrane electrode assembly and a gas diffusion layer are integrated, is formed, the unit cell injection mold includes an upper mold, a lower mold engaged with the upper mold to define an inner space between the lower mold and the upper mold, the inner space including an injection area into which the insert is accommodated and an insert area into which the polymer resin is injected to form the frame, and elastic protrusions formed from an elastic material, the elastic protrusions being disposed on the upper mold and the lower mold to face each other, wherein the elastic protrusions clamp the insert to divide the inner space into the insert area and the injection area to prevent the polymer resin from entering the insert area.

A mold for insert molding, which houses an electronic unit including a first circuit portion and a second circuit portion protruding from the first circuit portion, is prepared. The mold includes an upper wall surface facing an upper surface of the second circuit portion and side wall surfaces facing side surfaces of the second circuit portion. The flow resistance of a resin flowing through a space between each side surface of the second circuit portion and the corresponding side wall surface is lower than that of the resin flowing through a space between the upper surface of the second circuit portion and the upper wall surface. Then, the electronic unit is placed in the mold. Then, the resin is injected into the mold in which the electronic unit has been placed. Thus, the electronic unit and the housing in which the electronic unit is housed are integrated with each other.

An eletromagnetic coil, a mold, and an electromagnetic coil manufacturing method are provided. The eletromagnetic coil includes an annular main body, and an inner peripheral wall of the annular main body comprises multiple claw poles arranged at intervals in a circumferential direction. The electromagnetic coil further includes an encapsulation layer, and the encapsulation layer is capable of encapsulating an upper annular wall, a lower annular wall, and an outer peripheral wall of the annular main body. The encapsulation layer is not disposed between the claw poles, and is formed by injection molding of a resin material. In the electromagnetic coil, the encapsulation layer is not disposed between the claw poles of the inner peripheral wall of the annular main body, such that after moisture having entered the interior of the coil can be discharged therefrom within a short time.

A production method for a cover attached to an outer ring of a hub unit including procedures as follows. A nut is supported by a first protrusion of a first mold. By a second protrusion of a second mold, a core bar including a cylindrical section to be inserted into the outer ring is supported. A resin material is injected into a cavity formed by the first mold and the second mold to form a cover including a nut and a core bar. The cover is detached from the second mold by moving the first mold in a direction of being separated from the second mold. After this, the cover is detached from the first mold by pushing out the cover in a die matching direction with a pin disposed in the first mold.

A production method for a cover attached to an outer ring of a hub unit first prepares a first mold and a second mold which form a cavity filled with a resin material. Next, by a protrusion of the first mold, a nut is supported. Next, when viewed from an axial direction of the nut, in a state where at least a part of the gate of the second mold overlaps an inside of the nut as compared with an outer circumferential surface of the nut, the first mold and the second mold are die-matched. Then, a resin material is injected into the cavity.

A device for producing plastics parts having at least one rod-shaped metal insert, and comprising first and second mold half elements. At least one of the mold half elements is movable along a closure direction (Z). The mold half elements together can form a closed cavity for molding a plastics part, the insert projecting at least in portions into the cavity in order to be overmolded with plastics material, and being substantially arranged between the two mold half elements in a dividing plane which comprises a longitudinal direction (X) and a width direction (Y). At least one of the mold half elements has at least one fixing means wherein the insert can be fixed in the width direction. A positioning means can be arranged at a proximal end of the insert, allowing the insert to be moved along the longitudinal direction (X) into an injection position.

A device for injection-molding and for overmolding objects has an upper element and a lower element, which surround a contiguous volume consisting of a filling space for holding the object and casting material and a sprue for holding casting material. The upper element is movable in relation to the lower element. A piston is arranged within the upper element in an integrated manner and is movable relative to the upper element. The position of the piston can be varied in accordance with a dimension of the object in an axial direction and the piston has a protrusion for changing a volume as filling amount balancing of the casting material within the sprue such that the device is filled with a constant amount of casting material irrespective of the dimension of the object in the axial direction and a volume varying with the dimension of the object in the axial direction.

A system and method for making an anti-scatter grid device is provided. The method may include providing a mold including one or more orientation structures arranged in first positions. The method may also include placing a plurality of plates including a first material into at least one of the orientation structures, and injecting a second material into a first cavity in the mold formed by the plurality of plates and the orientation structures. The method may further include separating the plurality of plates and the hardened second material from the mold to generate a first module.
