  • Patent number: 8821782
    Abstract: A rim 58, 83 of a post cure inflator 60 can be changed in an easy and safety manner, while the amount of energy consumption is reduced. A inflator body 61 having the lower rim 58 can be located at a lower position, and the upper rim 83 can be moved downward to a lower position. Thus, the lower rim 58 and the upper rim 83 can be changed at the lower position in response to the change of the type of the tire to be manufactured, whereby the changing operation is made easy and safety. Further, the upper rim 83 moves upward. With this configuration, a vulcanized tire T having a heavy weight only moves in a front and rear direction while being supported by the inflator 61(lower rim 58), whereby the amount of energy consumption can be reduced easily.

  • Patent number: 8721954
    Abstract: In some examples, a method for densifying a material via pitch comprises inserting the material to be densified into a mold, wherein the mold is part of an apparatus. The apparatus may include a ram configured to apply a ram pressure sufficient to force a pitch into the mold to densify the material, a gas source configured to apply a gas pressure sufficient to force the pitch into the mold to densify the material, and a vacuum source operable to create a vacuum pressure in the mold at least prior to application of either the ram pressure or the gas pressure. The method may further comprise densifying the material in the mold via pitch using a selectable one of the ram, the gas source, the ram and the vacuum source, or the gas source and the vacuum source.

  • Patent number: 7595017
    Abstract: A system and method is disclosed for using a pre-formed film in a transfer molding process of the type that uses a transfer mold to encapsulate portions of an integrated circuit with a molding compound. A film of compliant material is pre-formed to conform the shape of the film to a mold cavity surface of the transfer mold. The pre-formed film is then placed adjacent to the surfaces of the mold cavity of the transfer mold. The mold cavity is filled with molding compound and the integrated circuit is encapsulated. The pre-formation of the film allows materials to be used that are not suitable for use with prior art methods.

  • Publication number: 20090148700
    Abstract: The invention mainly concerns a method for making a composite RTM part (23) which consists in producing a dry fibrous preform (8) by inserting in said dry preform (8) composite parts (10, 11) made of prepregs. Said parts, pre-impregnated with a first resin, are partly polymerized. The assembly is placed in a mold (16). A second resin is injected into the mold and impregnates the dry fibers (7). The two resins are polymerized simultaneously. The partial polymerization of the pre-impregnated parts (10, 11) results in a good chemical bonding between the two resins. The pre-impregnated parts (10, 11) have better mechanical properties, in particular in compression, than RTM parts. This is particularly due to a better alignment of the fibers (12) in the direction of stresses, and to a higher fiber volume ratio. The final component (23), reinforced with pre-impregnated parts, has better mechanical properties than the same RTM component without pre-impregnated reinforcements, in particular in compression.

  • Patent number: 7005101
    Abstract: The mold for a thin package uses a gate which has a high aspect ratio, about 30 degrees or greater throughout the length of the gate. Additionally, the depth of the gate goes to zero at a point outside of the area of the finished package, but within the dam bars, so that the leadframe space acts as a virtual gate. This reduces the need for trimming and lowers stress on the finished package.

  • Patent number: 6808661
    Abstract: A system is proposed for encapsulating in plastics material leadframe items comprising an IC wired to a leadframe. Dust of the plastics material is removed from the encapsulation system, and in particular from those items where dust principally accumulates, such as the surfaces of the molds. To reduce the level of dust which enters the molding region, the path along which the leadframe items are conveyed to the molding region is closed at times when the leadframe items are not being transported there. Additionally, the leadframe items are conveyed to the molding region under a cover including a vacuum source, so that the dust is continually sucked away from them.

  • Patent number: 6558600
    Abstract: A method and apparatus for encapsulating a microelectronic substrate. In one embodiment, the apparatus can include a mold having an internal volume with a first portion configured to receive the microelectronic substrate coupled to a second portion configured to receive a pellet for encapsulating the microelectronic substrate. A plunger moves axially in the second portion to force the pellet into the first portion and around the microelectronic substrate. The pellet has overall external dimensions approximately the same as a conventional pellet, but has cavities or other features that reduce the volume of the pellet and the amount of pellet waste material left after the pellet encapsulates the microelectronic substrate. Accordingly, the pellet can be used with existing pellet handling machines. The mold and/or the plunger can have protrusions and/or other shape features that reduce the size of the first portion of the internal volume.

  • Patent number: 6315936
    Abstract: Method for implementing a multi-phase plastic package for electronic components, and packaged electronic components produced according to the method. The present invention contemplates the use of molding compounds having two or more discrete phases in a transfer molding process wherein a temperature differential is induced between the electronic component to be packaged and the mold of the molding apparatus prior to molding. Each of the molding compound phases, when used in a current transfer molding apparatus, generates a separate layer in the resultant package, and each of the resultant layers possesses certain unique properties. In its simplest implementation, the present invention provides a two-phase molding compound pellet which provides an outer layer containing mold release compounds to facilitate release of the completed packaged device from the mold, and an inner layer without mold release agents. Other implementations include multiple layers.

  • Patent number: 6205659
    Abstract: A band-like raw material which becomes a contact plate is supplied to a position between an upper mold and a lower mold as these molds are closed, a convex part for the contact with the lower mold is engaged with a concave part for contact with the upper mold, by which, simultaneously punching out the contact part onto a part of the band-like raw material, the band-like raw material is cut to a predetermined length between edge parts to form the contact plate. At this time, a tip of a press pin on which the concave part is formed is brought into direct contact with a central part of the band-like raw material. A resin is injected into the mold cavities to form a push rod integrally with the contact plate, and the central part of the contact plate is deformed in the concave part to provide a stopgap.
