    • The invention relates to a method for producing plastic molded parts (2) with at least one closed cavity that is delimited by wall parts (3). The outer skin (4) is continuously or discontinuously produced in the shape of a tube and is introduced into a mold cavity (11) of a blowing mold (8) at a temperature located between the plasticizing temperature and the glass transition temperature. The outer skin (4) is placed, at least in areas, against shaping surfaces (12) of the blowing mold (8) by the establishment of a pressure difference between the cavity (5) of the molded part and an outer surface of the same, particularly by means of low air pressure. At least one supply (28) and discharge (58) line is produced between the blowing mold (8) and the cavity (5) of the molded part (2). At least one pressure medium is introduced into the cavity (5) of the molded part (2). The air is removed by suction, at least in areas, between the shaping surface (12) of the blowing mold (8) and the outer surface (13) of the molded part (2) via pores of a porous material that forms the blowing mold (8).
    • 本发明涉及一种用于制造具有至少一个由壁部件(3)和自包含的空腔界定由塑料制成的成型件(2)。 外蒙皮(4)由筒状的连续或不连续的,并引入在吹塑模具的一个模腔(11)的Plastifizierunstemperatur和玻璃化转变温度之间的温度(8)。 外蒙皮(4)至少部分地在吹塑模具(8)的表面(12)的形式,通过在吹塑模具之间产生负压的装置建立所述模制零件的所述腔(5)和相同的外表面之间的压差,特别是(8)和 模制(2)的至少一个入口和(28)衍生物(58)的空腔(5)的制备。 在所述腔(5)的模制的(2)在吹塑模具(8)的模具表面(12)和模制品的外表面(13)之间至少部分地(2)经由一多孔的,吹塑模具的孔(8)形成材料被吸入 ,
