摘要: A mold station for hot shaping plate-shaped polymer-bound plastics, thermoplastics, mineral plastics, into three-dimensional molded bodies such as bathtubs, sinks, washbasins, washstands, facings and shields, furniture parts, work surfaces, window sills and the like with a mold arrangement accommodated in a frame and in which are located at least one mold part for receiving the material to be molded, a membrane clamped over the mold part. The membrane is substantially impermeable to gas and elastically stretchable. A pressure difference is generated between the two sides of the membrane, characterized by the additional provision in the frame of the mold arrangement of a heating or cooling arrangement with two plate-shaped heating or cooling elements for pre-tempering of the material to be molded that can move in two directions that are substantially vertical with respect to each other.

摘要: A thermal interface material for interfacing with at least a first surface. One embodiment of the thermal interface material includes a plurality of thermally conductive, malleable fibers arranged in a pattern. The fibers contact each other so as to reduce air gaps and fill irregularities when the fibers are compressed against the first surface.

摘要: A method and apparatus are provided for forming a sheet of polymeric material, such as polycarbonate. A forming mold is provided having halves that engage for forming a heated sheet therebetween. Each of the halves defines an interior cavity having a peripheral edge. The sheet is retained between the peripheral edges of the halves and a vacuum is generated within one of the cavities for drawing the sheet therein, whereby a sensing mechanism detects a draw depth for initiating a cooling mechanism to cool the sheet to a temperature below a glass transition temperature of the material. A series of retention mechanisms are provided about the peripheral edge of one of the halves, for biasing the sheet into engagement with the peripheral edge of the opposing half. A trimming mechanism is further provided for trimming the perimeter of the sheet to a desired form.

摘要: A container for holding food items and the like. The container comprises a base for holding the food item and a cover hingedly mounted to the base and movable between an open and closed position. The cover has a latch wipe opening that is sized to receive a tab extending from the base. The latch wipe opening has a generally rectangular shape. During the manufacturing process, the material in which the latch wipe opening is formed is pre-cooled to reduce the tendency of the latch wipe opening to deform. Further, the form against which the latch wipe opening is formed has a knurled portion that engages the container material above the latch wipe opening to further prevent the deforming of the latch wipe opening during manufacturing.

摘要: A simultaneous twinsheet thermoforming system having a carousel rack to simultaneously move two sheets of thermoplastic together through a heating station and a forming station. The two thermoplastic sheets are vertically disposed on upper and lower tiers of the rack. The single heating station includes vertically disposed upper and lower ovens, which both sheets pass through simultaneously. The ovens each include upper and lower heating platens, the lower platens being movable to accommodate for sagging thermoplastic. The forming station includes upper and lower vacuum molds that are movable from an open position to a closed position. In the open position, the two sheets are moved in between the mold faces. The molds are driven together to contact the sheets and simultaneously form the two sheets to the two molds. At least one of the two molds is further moved to establish contact between at least portions of the two sheets, thus fusing them together.
