    • The preform is formed by an upper neck which maintains unchanged its form in the final object and a hollow body, joined to the neck. The method foresees the insertion, within a matrix cavity, of a metered body of polymeric material whose mass is metered according to a reference value, and the subsequent pressure insertion of a punch within the matrix cavity until it closes the mold's molding chamber, the punch conferring the shape to the inner surface of the preform and the matrix having an inner surface which confers the shape to the outer surface of the preform. According to the invention, in the molding of the preform, the error of the mass of the metered body with respect to the reference value is distributed in the hollow body, which undergoes a subsequent hot deformation until it achieves the final shape. In the mold, the matrix comprises at least one deformable wall (31) whose inner surface defines at least part of the inner surface of the matrix part intended to give form to the hollow body of the preform, said deformable wall (31) having, at least in part, a relatively thin thickness which permits it to be elastically deformed under the pressure of the polymeric material in the final preform molding step, thereby varying the thickness of the hollow body.
    • 预成型件由上颈部形成,上颈部保持其最终物体中的形状不变,以及与颈部接合的中空体。 该方法预见在矩阵腔内插入聚合材料的计量体,其质量根据参考值进行计量,以及随后的冲头在基体腔内的压力插入,直到其关闭模具的模制室,冲头 将形状赋予预成型件的内表面,并且基体具有将形状赋予预成型件的外表面的内表面。 根据本发明,在预成型件的成形中,计量体的质量相对于基准值的误差分布在中空体中,中空体经历随后的热变形直到达到最终形状。 在模具中,基体包括至少一个可变形壁(31),其内表面限定用于给予预制件中空体的基体部分的内表面的至少一部分,所述可变形壁(31) 至少部分地具有相对薄的厚度,其允许其在最终预成型件模制步骤中在聚合物材料的压力下弹性变形,从而改变中空体的厚度。
