摘要： There is provided a die 1, for molding disc substrates, wherein, in a stamper 20, a to-be-held surface 33 that diverges continuously from an inner circumferential surface 32 of a center hole 31 is formed between the inner circumferential surface 32 and an inner circumferential side head surface 34 by punching the center hole 31, an inner stamper holder 16 that holds the inner circumferential side 20a of the stamper 20 includes a cylindrical body portion 41 and a claw portion 42, in the claw portion, a cavity forming surface 43 that is substantially parallel to the inner circumferential side head surface 34 of the stamper 20 and a holding surface 46 that diverges toward the cavity in a tapered fashion and holds said to-be-held surface 33 are formed, and, in the cylindrical body portion 41, a cylindrical surface 47 that is opposed to the inner circumferential surface 32 of the stamper 20 is formed. The die 1 for molding the disc substrates prevents the claw portion 42 of the inner stamper holder 16 from being projected from a transfer surface 35 of the stamper 20 and solves a problem of insufficient strength of the inner circumferential side of the stamper 20.

摘要： A method and a system is provided for producing a needle of plastic, as well as a needle of plastic, in particular a needle for medical purposes. The method produces a needle having at least the outer diameter of one end being less than 0.50 mm using a moulding system having an assembly comprising a feed system and a mould cavity. The method includes introducing a melt of plastic into the feed system, increasing the melt pressure gradually during melt passage through the feed system, passing the melt into the mould cavity whereby the melt substantially fills the mould cavity, cooling the melt in the mould cavity whereby the melt solidifies to a needle, and removing the needle from the mould cavity.

摘要： In order to produce a plastic part 5 that has an opaque body 1 and a front surface with at least one translucent area delineated from an opaque area, in a first step, a blank with a recessed volume 2 is formed by means of injection molding using an opaque plastic component. The recessed volume 2 extending from an opening in a face of the blank and inwardly of the blank corresponds in shape and position to the translucent area. In a second step, at least the face of the blank is over-molded with a layer of a coloured plastic component. Hereby, the opening in the face of the blank is over-spanned by a layer of this coloured plastic component being sufficiently thin to be translucent.

摘要： A method of manufacturing injection-molded components having complex features is disclosed. Prior methods typically require the use of a three-piece mold system to form an injection molded component having a complex feature, such as a lawn mower hood having a parabolic shaped front. With the development of a new rigid type of reflective material the present method can thereby utilize a two-piece mold system to form an injection molded component having complex features such as a lawn mower hood having a C-shaped open cavity located at the front of the hood.

摘要： A method and apparatus for producing molded fluoropolymer sweep elbows with straight ends while minimizing distortion of the fitting. The invention includes a mold for creating the sweep fittings of the invention. The mold includes a mold cavity block and internal coring. The internal coring includes two symmetrical cores that shut off at a 45null miter. Each of the symmetrical cores is divided into two parts, an outside sweep core and an inside sweep core. The outside sweep core and the inside sweep core are divided on a straight plane running the length of the core. The outside sweep core molds half of the straight lumen and the greater curvature at the outside sweep surface of the bend. The inside sweep core molds the other half of the straight bore and the lesser curvature of the inside or undercut portion of the bend.

摘要： An injection molding method that ensures, in the molding of optical disks and the like, accurate transferability, optical characteristics and mechanical characteristics for accurately transferring a super fine structure that could not be transferred satisfactorily by the conventional molding method, mass production of replicas, and so on, thus improving the production efficiency. It comprises the steps of using a cavity forming mold composed of at least two members, charging molten resin into the mold, obtaining a molding, wherein one of the members constituting the mold passes through a stage that is separated into at least three steps, a charging step, a press step and a molding take-out step, and molten resin is charged into the unclosed cavity of the one member in the charging step and then a molding is formed in the press step.
