摘要： The invention relates to a method of producing a preform from a slowly-crystallizing semicrystalline amorphous polymer. The inventive method comprises the following steps consisting in: plasticizing (in 3) the polymer by rapidly increasing the temperature to a temperature below the melting temperature; pushing the plasticized polymer through a die (4); at the outlet of the die, sweeping the polymer with a dry inert gas (11); collecting the plasticized polymer in a first container (6), while maintaining the polymer at the plasticification temperature during all of the steps; and die-stamping (13) same in the first container or in a second container, to which it is transferred from the first, with quenching such as to obtain the preform in an amorphous state.

摘要： An apparatus for transferring a charge of plastic material to a molding machine having a mold with a mold cavity (24). The transfer apparatus includes a hub (66) rotated about an axis (56), at least one arm (70) extending generally radially from the hub to rotate with the hub around the axis (56), and a cam system (74) operably coupled to the arm (70) for moving the arm along a path with respect to the axis (56) as the hub and the arm rotate around the axis. In one embodiment, at least a portion of the arm travels along a plane that is parallel to the axis during a portion of the path.

摘要： A device for producing a ring-shaped body, comprises a preforming unit (200) with a ring nozzle (220) for producing a ring-shaped preform (410) by extruding a thermoplastic material, a stripper (113) for stripping off the preform (410) and a forming tool (111) for forming the ring-shaped body by compressing the preform (410) against a counterpart element (300, 400) into a desired profile. The ring-shaped body is produced by first producing a ring-shaped preform (410) by extruding a thermoplastic material through the ring nozzle (220), stripping off the preform (410) from the ring nozzle (220) and forming the ring-shaped body by compressing the preform (410) against a counterpart element (300, 400) into a desired shape. The ring nozzle (220) allows for a fast production of an even, ring-shaped preform (410) by simultaneously forming the ring along its entire circumference. Because of the ring nozzle (220), mechanically complex rotating parts such as a rotating dispensing head are not required. The stripper (113) ensures that the preform (410) is fully and evenly detached from the ring nozzle (220) with no material remaining that could block the nozzle (220). Due to the forming tool (111) the stripped-off preform (410) can immediately be compressed to obtain its final form, depending on the shape of the forming tool (111) and the counterpart element (300, 400). As no reheating of the preform (410) is required, the construction of the device is simplified.

摘要： A composite magnetic sheet having excellent electromagnetic wave absorption characteristics is manufactured simply by rolling a pulverized mixture of powder comprising flat particles of a soft magnetic material and an organic binder by two opposed rolls. A plurality of such composite magnetic sheets having roughened lamination surfaces are stacked and the sheets are rolled to attain a desired thickness. By rolling two composite magnetic sheets with a mesh metal layer sandwiched therebetween, a mechanically strong, electromagnetic interference-restraining sheet is easily obtained. In order to reduce the reflection and permeation of electromagnetic waves on and through the composite magnetic sheet, the upper and lower surfaces thereof are subjected to an embossing process.

摘要： A method for molding panels (44) in a sheet molding system comprised of a thermoplastic sheet delivery station (10) and two mold halves (18), the method comprising the steps of delivering two sheeting layers (12, 14) of thermoplastic material between the two mold halves; inserting a regidizing insert (40) between the two sheeting layers of thermoplastic material; closing the mold halves to bring the two sheeting layers of thermoplastic material in contact with the insert; and compressing the thermoplastic sandwich between the mold halves to form a panel. A thermoplastic-insert sandwich and a laminate panel comprised of thermoplastic layers abutting a pre-manufactured insert are also claimed.
