    摘要： A process for producing a concrete form made of thermoplastic resin by a press-molding process by feeding a reinforcing material-containing thermoplastic resin (1) heated to a temperature not lower than the melting temperature of the resin into the cavity between male and female halves of a die (2,3), clamping the die and cooling the die, wherein the press-molding is carried out under the conditions that the period of time from completion of feeding the melted resin to completion of clamping is not longer than 6 seconds and flow length L of the fed resin and thickness T of the molded product satisfy the formula 190 ≦ L/T.

    摘要： A mold for compression molding a resin article, which mold consists of male and female molds, wherein, at the time of complete mold closing, the shortest length L in a mold closing direction of a mated part formed between the outermost wall of said male mold to which a resin melt con­tacts and the innermost wall of a flange of said female mold satisfies the equation:
    (t₁ - t₀ + 10) mm ≧ L ≧ (t₁ - t₀) mm
    wherein t₁ is a distance (mm) between the male and female molds when the resin melt first reaches the horizontally outermost edge of the male mold, and t₀ is a distance (mm) in the mold closing direction between the same points on the male and female molds as those used for measuring t₁, and the shortest horizontal distance of a mating gap between the horizontally outermost wall surface of said male mold and the horizontally innermost wall surface of said female mold is from 0.02 to 0.1 mm, with which mold, squeeze-out of a resin melt during molding is prevented.

    摘要： A molded article of a fiber-reinforced thermoplas­tic resin which suffers less deformation and has good appea­rance is produced by a method comprising the steps of:
    supplying at least two porous fibrous sheets (3, 4)
    supplying a melt mass of a thermoplastic resin (5) in a space between said porous fibrous sheets, and
    forcing said resin melt to fill the pores of the porous sheets by resin supplying pressure and/or pressing pressure and to reach the outer surface of said porous fibrous sheets.

    摘要： The present invention relates to a process for producing a multilayer polyolefin foamed sheet, and concretely to a process and an apparatus for producing a multilayer polyolefin foamed sheet which has a smooth surface and is excellent in vacuum formability. Further, the present invention specifically relates to a multilayer polyolefin foamed sheet excellent in vacuum formability and to a foamed container body and a foamed container using the same.
    As a producing method of the present invention, for example, a method for producing a multilayer polyolefin foamed sheet comprising at least one polyolefin foamed layer and at least one polyolefin non-foamed layer, wherein the method uses a producing apparatus (1) comprising at least one first extruder (3) for extruding a material for forming a polyolefin foamed layer wherein the first extruder (3) is equipped with a foaming agent-supplying device for supplying a foaming agent to a cylinder, at least one second extruder (5) for extruding a material for forming a polyolefin non-foamed layer and at least one extrusion die (7) for co-extruding the material for forming a polyolefin foamed layer and the material for forming a polyolefin non-foamed layer therethrough to form the multilayer polyolefin foamed sheet, the method comprising:

    a melt kneading step in which, in the first extruder (3), a resin material for forming a polyolefin foamed layer is melted and the melted resin material for forming a polyolefin foamed layer and a foaming agent supplied from the foaming agent-supplying device (6) are mixed to form the material for forming a polyolefin foamed layer;
    a melting step in which the material for forming a polyolefin non-foamed layer is melted in the second extruder (5); and
    a co-extruding step in which the material for forming a polyolefin foamed layer and the material for forming a polyolefin non-foamed layer in their melted states are co-extruded into atmospheric pressure though the extrusion die (7) and the extruded material for forming a polyolefin foamed layer is foamed to form the multilayer polyolefin foamed sheet, and the like is provided.
