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).
摘要:
The present invention relates to a method and apparatus for positioning a disc, such as a barrier disc (20), in a closure (40). In particular, the invention relates to a method and apparatus for positioning a barrier disc (20) in a self-sealing moulded plastic closure (40) having a sealing fin arrangement (22) for providing a seal when the closure (40) is appropriately applied to a finish of a container (30). The method comprises the steps of providing a barrier disc (20) in a position ready for insertion within the closure (40); pressing the barrier disc (20) relatively into the closure (40) such that at least a portion of the disc (20) is positioned at least adjacent the top panel thereof; and applying a fluid pressure to the barrier disc (20) such that the entire disc is forced into a position at least adjacent the top panel. The apparatus comprises an insertion station for supporting the closure (40) through the disc positioning process and a tool (50) that is movable relative to the insertion station to drive the disc (20) relatively into the closure (40). The tool (50) comprises a plunger (55) adapted to press the disc (20) into the closure (40) such that at least a portion of the disc (20) is adjacent the top panel thereof, and a fluid flow passage through which fluid travels to apply fluid pressure to the disc (20) and force the entire disc (20) past the sealing fin (22) and into a position at least adjacent the top panel.

A surface treatment of an light transmission layer by spin coating is carried out in a simple way at low cost. When an light transmission layer is to be formed by spin coating, the transfer of an information recording layer 108 is carried out using a resin stamper 140 having a convex portion 140A in an outer peripheral portion. At the same time, an inclined plane (concave portion) 135A is formed on the side of a substrate (member on which transfer is performed) 104. As a result, coating is achieved in such a manner that a raise in the outer peripheral portion is prevented from being noticeable.

A multilayer molded piece is produced by using a composite skin constituted by a skin material and a foam sheet and having a tensional modulus of elasticity of 950 kg/cm² or lower and satisfying the relationship among tension modulus of elasticity E (kg/cm²), heat shrinkage F (%), and thickness (t) as defined by the following expression: 20/(E x t) + F ≧ 2.5 . A large and complicatedly shaped multilayer molded piece is provided which has a good appearance which is free from breaks and wrinkles, as well as from uneven marks on the skin material on the surface thereof.

摘要:
A molding machine for making thermoplastic composites contains: a machine frame (10), a platform (20), a heating device (30), a vacuum means (40), and a gas barrier film (60). The machine frame (10) includes a working stage (11). The platform (20) is mounted on the working stage (11) and includes channels (22), a curved pattern portion (23) and plural tiny holes (24) which are arranged on the top surface of the platform (20), wherein the plurality of tiny holes (24) communicate with the channels (22). The platform (20) also includes a connector (21) fixed on one side thereof and communicating with the channels (22). The heating device (30) is secured on a bottom end of the platform (20) and heats a working material on the platform (20). The vacuum means (40) is arranged in the machine frame (10) and includes a pipe (41) for coupling with the connector (21). The gas barrier film (60) is flaky and covers the top surface of the platform (20).
摘要:
An imprint device and an imprint method are provided which form mold patterns on both surfaces of a molding target. An imprint device transfers mold patterns on both surfaces of a molding target 2 using flexible first and second dies 1A, 1B, and the device includes a first casing 33A that applies pressure of a first pressurizing room 30A to the die 1A and the molding target 2, a second casing 33B that applies pressure of a second pressurizing room 30B to the die 1B and the molding target 2, a pressurizer 35 that adjusts the pressures of the pressurizing room 30A and the pressurizing room 30B, a first moving unit that moves the die 1A and the molding target 2 in a direction coming close to or distant from each other, a second moving unit that moves the die 1B and the molding target 2 in a direction coming close to or distant from each other, a depressurizer 45 that depressurizes a depressurizing room 40 formed between the casing 33A and the casing 33B, and eliminates fluids present between the die 1A and the molding target 2 and between the die 1B and the molding target 2, and a pressure adjuster that adjusts pressures so as to reduce pressure differences between the depressurizing room 40 and the pressurizing room 30A, the pressurizing room 30B.
摘要:
The present disclosure relates to an embossing or pressing system and method where a plastic blank may be embossed during a production cycle between a first (1) and a second (3) tool half in order to provide the blank with a desired shape or a desired surface pattern. A sealing device (11), is used which connects the first and second tool halves, during a step in the production cycle when a blank is inserted between the tool halves but prior to pressing, in such a way that a closed space is formed between the tool halves. A pumping device (15, 17, 25), is adapted to lower the pressure in said closed space in order to remove air from the cavity. This mitigates the risk of air pockets being trapped between each of the tool halves and the blank when pressing/embossing takes place.
摘要:
A die (10) for pressing plastic material with a covering film (12) between the plastic material and the moulding wall (11) includes passages (14) made in the moulding wall and connected to a source of vacuum (15) to facilitate adhesion of the film to the wall. In the passages (14) there is a filter element (16) equipped with a removable filter (19) which can be easily replaced if the plastic material comes into contact with it.
