A method for producing a composite sealing element, in particular for forming a seal at a retractable pane of a vehicle window, wherein the composite sealing element is produced from at least one extruded element portion and at least one element part formed by injection molding in a mold cavity of a mold, with the element part being molded onto an end face, bounding the mold cavity, of the extruded portion. A change in the dimensions of the composite sealing element as a result of the length of the extruded element portion differing from the nominal value is counteracted by changing the arrangement of the end face of the extruded element portion with respect to the mold cavity.

A new type of RFID tag is provided. A gaming chip that incorporates a sticker-type RFID tag comprises: an enclosing member having a predetermined shape for enclosing the RFID tag; a body member that is injection-molded to encapsulate the enclosing member with the RFID tag; and a gaming chip for amusement. The enclosing member consists of a first part and a second part, and at least the first part or the second part has a flat surface to which a sticker-type RFID tag can adhere, and the first part and the second part are combined to form an enclosing member, in which the sticker-type RFID tag is covered by the first part and the second part.

The present invention is intended to provide a manufacturing method of an insert molded article that makes it possible to manufacture efficiently the insert molded article including a metallic insert, an inside member made of a synthetic resin and covering a portion of the insert, and an outside member made of a synthetic resin different from the material of the inside member and covering a portion of the inside member using general molding machines, not a dedicated two-color molding machine.

General molding machines are used to manufacture the insert molded article formed by injection molding of a resin part in twice. An insert core 7 is used in common in primary molding using a primary molding die C1 and in a secondary molding using a secondary molding die. A round shaft 7C of the insert core 7 is fitted into an internal hole 2C of an insert 2 to form a coupled body 10 in which the insert 2 and the insert core 7 are coupled together. The coupled body 10 is used in common at the primary molding step and the secondary molding step.

By a simple configuration, contact members can be well retained with a housing in a mutually opposed state, and productivity can be improved. When the contact members in the mutually opposed state are to be attached to the housing, a contact retainer prepared by molding in advance is used by disposing the contact retainer in part of the contact opposed region. As a result, the contact members are stably retained in the mutually opposed state even in injection molding molds. Even in a case in which the contact members normally cannot be retained in the mutually opposed state in the injection molding molds, the housing and the contact members can be integrally molded by well retaining the contact members in the mutually opposed state by using the contact retainer and a contact retainer auxiliary and executing an injection molding process.

The present invention provides a connection structure and a manufacturing method therefor capable of increasing reliability of a connection part compared to the prior arts. A connection structure according to the present invention includes a plurality of conductive members, a connection part that electrically connects the conductive members, and an electrically insulating molded body in which the connection part is embedded. It is thereby possible to physically reinforce the connection part of the conductive members, keep the connection part in a hermetically sealed condition, thereby prevent corrosion and increase reliability compared to the prior arts.

A lead connector for an implantable medical device includes a cylindrical connector body having a proximal end and a distal end. A distal frame forms the distal end and a remainder of the connecter body is a mold material. A plurality of shafts extending through the distal frame from a rear face to a front face, the rear face abutting the mold material forming the remainder of the connector body. A plurality of ring contacts are in the connector body. A plurality of wires are coupled to a ring contact and extend through the mold material and through a corresponding one of the shafts. The mold material forming the remainder of the connector body extends partially into each shaft and about the corresponding conductive wire to form a plug.

The equipping of syringe barrels (11) with needles (25) takes place before the injection of the plastic, in which the needles (25) are introduced through the fixed part (5) of the injection mold (1) by a suitable transport device (transport rollers 33).

A holding portion having a diameter larger than that of a cavity is formed in communication with the cavity, in an area of a two-part type mold, the area including a portion corresponding to an annular groove. Subsequently, an insert member formed in a cylindrical shape and provided with, on an outer circumferential surface, the annular groove having no step in a groove surface is fitted to the holding portion, and then the mold is closed. On an inner circumferential surface of the insert member, a surface treatment layer having a surface roughness rougher than those of other portions of the insert member is formed. Molten resin is injected into the cavity; thereafter, an assist material is injected into the cavity to mold the resin into a desired pipe body. Then, the insert member and the pipe body are integrated along with curing of the resin.

The present invention discloses a humanized heavy hammer structure, comprising a plastic body, a configuration metal block and a fixed block, wherein the plastic body is provided with a swing arm, an accommodating part and a U-shaped accommodating space, the configuration metal block and the fixed block are sequentially arranged in the U-shaped accommodating space, the accommodating part is an-armed along; the outer periphery of the plastic body, the swing arm can swing around the plastic body, and when closed, the swing arm and the accommodating part are mutually buckled, the configuration metal block is completely covered between the plastic body and the fixed block, and the configuration metal block is provided with a U-shaped notch, the fixed block is arranged in the U-shaped notch and connected with the configuration metal block, and a hose is provided in the middle of the fixed block. The present invention through the structural design of the fixed block and the counterweight metal block can effectively solve the problem that the counterweight metal of the product produced during the injection molding process is exposed outside; and the whole heavy hammer structure can be more conveniently mounted and dismounted in an integrated U-shaped design mode of the heavy hammer structure.

A roller shaft is inserted into a mold including molding members respectively having a first mold surface that defines an outer circumference of a roller portion and second and third mold surfaces that respectively define first and second flat portions of the roller portion, and the mold is then closed. A molding material is injected around the roller shaft to integrally mold the roller portion. The roller portion includes the outer circumference and the first and second flat portions rising from the roller shaft to the outer circumference. The roller shaft includes flange portions at portions corresponding to the first and second flat portions. The flange portions prevent the molding material from leaking outside the first and second flat portions when the roller portion is integrally molded around the roller shaft by injection molding.
