Abstract:
An injection molded part is formed of a base part and a soft component which includes a cushioning shaped part fastened thereto. Injection (molding is performed without additional connection steps by having the cushioning shaped part have a soft, cast gel body completely covered on its boundary surface with a hard component that is a flexible and elastically deformable material which forms a circumferential flange-like rim protruding laterally beyond the cast gel body. During injection molding the hard component is being surrounded by the material of the base part while shielding the cast gel body from the injected material used to form the base part.
Abstract:
A cable harness is surrounded in certain regions by a sheath made of a casting compound. In order to ensure a defined delimitation of the casting compound, even if there is an insert part protruding from the sheath, the method for sealing a tool opening provides that a pressure element is pressed in the radial direction against the insert part. The insert part is clamped between the pressure element and a support element, and the support element remains in the cable harness as a consumable element. The insert part is particularly designed as a heat protection element. The cable harness is used particularly in a thermally stressed environment for a motor vehicle.
Abstract:
A laminated rotor core (36) wherein permanent magnets (47) are inserted in respective magnet insertion holes (46) is disposed between and pressed by an upper die (37) and a lower die (29). The upper die (37) has resin reservoir pots (50) provided above the laminated rotor core (36) and at positions corresponding to the respective magnet insertion holes (46). Raw resin material put in the resin reservoir pots (50) is heated by the upper die (37). Subsequently, the resin material in a liquefied state is ejected from the resin reservoir pots (50) by plungers (52) that are inserted and moves vertically in the resin reservoir pots (50) and is directly filled in the magnet insertion holes (46). Consequently, the respective magnet insertion holes (46) are filled with the resin material more evenly and highly reliable products can be supplied at low cost.
Abstract:
A tapped insert to be insert molded comprises a shank provided at its axial ends with flanges delineating two axially opposite heads of the insert. The shank is provided with an internally threaded axial section to form a tapping. Means for blocking the insert in rotation after insert molding and means for blocking the insert axially in translation after insert molding are arranged on the outside of the shank. The shank comprises at least one fusible area of greater axial deformability located between the threaded axial section and one of the heads. The fusible area is configured to deform under a predefined axial compressive force applied to the heads without causing deformation of the threaded axial section.The invention also relates to a method for insert molding such an insert.
Abstract:
An insert mould tool for moulding an annular moulded portion onto an insert such as a filter sheet of a filter cartridge comprises a plurality of mould pieces and means for applying pressure to the mould pieces. Each mould piece comprises complementarily shaped mating surfaces and can be assembled to define an annular mould cavity intersecting at least one mating surface for defining the shape of the moulded portion and an insert-receiving cavity for receiving a portion of the insert. The insert-receiving cavity comprises a sealing portion extending radially inwardly of the annular mould cavity for sealing receipt of a portion of the insert, the sealing portion being exerting a substantially evenly distributed pressure across an area thereof when pressure is applied to the mould pieces. Also disclosed is a method of insert moulding, and a filter cartridge.
Abstract:
A method for producing a carpet mat by injection molding, includes providing an injection mold including a cavity and a complementary core, each defining a portion of a mold recess for accommodating the finished carpet mat, providing the cavity with a surface having at least one vacuum opening bordered by a peripheral retaining barrier, applying vacuum to the core, inserting a sheet of carpet into the recess of the cavity and against the surface so that the carpet is in contact with the cavity, so that the carpet is held in the recess by the vacuum. Next, the cavity and core are closed together, thus sealing the recess, and a flowable supply of plastic is injected into the recess. Finally, the mold is opened after a specified period, allowing the plastic to at least partially solidify.
Abstract:
A method of forming a filter unit comprised of a filter element and an encircling peripheral encasement frame to which the filter element is sealed. The frame is moulded in situ by solidification of a liquid, solidifiable moulding composition (e.g. a curable resin or a matter thermoplastic resin that solidifies on cooling) provided around the periphery of the filter element. The method may comprise the steps of: (i) providing a filter element having front and rear faces and a bounding peripheral edge, (ii) locating around the peripheral edge of the element a mould unit which seals against peripheral regions of the front and rear faces and which together with the peripheral edge defines a mould cavity, (iii) filling the mould cavity with a solidifiable, liquid moulding composition, (iv) effecting conversion of the liquid to a solid, and (v) removing the mould thereby producing the filter element.
Abstract:
A multi-film junction structure includes an upper mold having a downwardly extending protrusion formed at a lower surface thereof to allow a recess to be defined in resin that is injected therearound. A first film is attached to a part of the lower surface of the upper mold and a side surface and lower surface of the protrusion, the first film having an extension extended from the lower surface of the protrusion by a predetermined length. A second film is attached to a remaining lower surface of the upper mold and an opposite side surface of the protrusion, the second film having a coupling portion located inside the extension of the first film, wherein the extension is bent upwardly. Additionally, a lower mold is provided having a recess facing the protrusion of the upper mold while being spaced apart from the protrusion, the lower mold defining an injection molding space together with the upper mold for allowing resin to be introduced and injection molded in the space.

Abstract:
A molding machine for encapsulating electronic devices mounted on one side of a substrate, and having a ball-grid array, pin-grid array, or land-grid array on the opposite side, has a two member biased floating plate apparatus to compensate for variations in substrate thickness, and a gas collection/venting apparatus for relieving gases emitted from the non-encapsulated underside of the substrate.
