摘要:
A forming tool (6) for forming a semi-finished product (2) comprising reinforcement fibers and being conveyed to the forming tool (6) in a continuous process is provided. The forming tool (6) comprises at least one pressure bag (8, 8a to 8e) configured to be pressurized during a forming step of the semi-finished product (2), during which the semi-finished product (2) is sandwiched between a forming surface of a forming element (4) and the at least one pressurized pressure bag (8, 8a to 8e), such that the semi-finished product (2) substantially takes on the shape of the forming surface. Further, a forming apparatus and a forming method for forming a semi-finished product (2) comprising reinforcement fibers are provided.

Apparatus (200) for forming a composite component is disclosed, the apparatus comprising: a deformable mould tool (204) that at least partially defines a mould cavity (212); an interface layer (222) formed on an external surface of the mould tool (204); and at least two peristaltic actuators (206), mounted to contact the interface layer (222) and to generate a peristaltic pressure wave in the mould tool (204). The peristaltic actuators may comprise rollers (206), pistons (306) or bi-metallic blocks (406). A method of forming a composite component is also disclosed, the method employing a mould tool (204) that at least partially defines a mould cavity (212). The method comprises: placing reinforcing fibres into the mould cavity (212), forcing a matrix material into the mould cavity (212) through the reinforcing fibres, and generating a peristaltic pressure wave within the mould tool (204) during forcing of the matrix material into the mould cavity (212).

A system for forming a composite structure (106) comprises an electromagnetic press (12) including an upper die (26), a lower die (28) and an electromagnet (42). The lower die may be mounted in spaced relation to the upper die for receiving a composite layup therebetween. The electromagnet is energizable such that the upper and lower dies apply a compressive force to the composite layup.

Deterioration of transfer characteristics from a molding die to a resin is suppressed. A method for manufacturing a wafer lens is provided with: a first step of moving a glass substrate (3), which has a photo-curable resin (5A) dropped thereon, to a predetermined position with respect to a sub-master (20) by controlling the position of the glass substrate (3), and holding the glass substrate (3) at such predetermined position; a second step of irradiating the photo-curable resin (5A) with light; and a third step of holding the pressing force of the glass substrate (3) to the sub-master (20) at a predetermined pressure by pressure-controlling the glass substrate (3).

Es werden Walzen (1) und deren Verwendung zum Ausüben von Anpressdruck auf eine oder mehrere Materialbahnen (10,11) beschrieben. Gemäß einer Ausführungsform weist die Walze (1) eine Walzenachse (2) auf, auf der sich eine Mehrzahl von Scheiben (3) befinden. Diese Scheiben sind radial beweglich und üben den Anpressdruck auf die eine oder mehreren Materialbahnen aus. Der Anpressdruck der Scheiben (3) kann pneumatisch oder hydraulisch gesteuert werden. Derartige Walzen kommen insbesondere bei der Verbindung von gummiartigen Materialbahnen (10,11) im Rahmen von Reifenherstellung zum Einsatz.
摘要:
An apparatus for manufacturing products from a material which is thermoplastically deformable, as from plastic, comprising: - a mold with at least one mold cavity; - in the or each mold cavity at least one slide; - movement means for moving each slide; - closing means for opening and closing the mold; - feed means for introducing, with the mold cavity closed, said material in at least substantially plastic condition into the or each mold cavity;
wherein the movement means for moving the slide are arranged for moving said slide forward at a relatively high speed relative to the movement speed of the mold parts upon opening and closing thereof, from a position at least partly retracted from the mold cavity, such that said material, as a result, is displaced in the mold cavity for obtaining the filling thereof, preferably at a speed high such that adiabatic heat development occurs in the or each mold cavity.

The invention relates to a method for producing a molded element, which method comprises the following steps: introducing a melt into a molding tool (102, 104), increasing the pressure of the melt to such a degree that the melt solidifies, and cooling the solidified melt. The invention also relates to a control for a machine and to a computer program product.
摘要:
A resin sealing semiconductor package and a method and a device for manufacturing the semiconductor package. The method for sealingly molding the semiconductor package is characterized in that a powder or granular resin composition is agitated and molten in an agitating pot having a heating device by rotating an agitating plunger having an agitating bar projected from the tip thereof, the agitated and molten resin is taken out and pressurized in a package shape to manufacture a shaped resin, the shaped resin is mounted on a compression plunger in a drag cavity, and the compression plunger is pressurized after a mold is clamped. Thus, even ifa wire is reduced in size or made highly dense, the flow of the wire is hard to occur.
