    • A method for compression-moulding a dose (10; 210) of plastics in a mould (6; 106) having first forming means (7, 20, 22; 107) and second forming means (9) comprises the steps of : moving said first forming means (7, 20, 22; 107) towards said second forming means (9) at a speed that is variable according to a preset profile, said preset profile being so chosen as to apply reduced stress to said plastics, in order to obtain an object (1) from said dose (10; 210); maintaining said object (1) in said mould (6; 106) while applying variable pressure to said plastics according to a preset further profile, said preset further profile being so chosen as to reduce the stress in said plastics; - extracting said object (1) from said mould (6; 106).
    • 一种用于在具有第一成形装置(7,20,22; 107)和第二成形装置(9)的模具(6; 106)中压塑塑料剂量(10; 210)的方法,包括以下步骤: 以可根据预设轮廓变化的速度朝向所述第二成形装置(9)的第一成形装置(7,20,22; 107),所述预设轮廓被选择为对所述塑料施加减小的应力,以便 从所述剂量(10; 210)获得物体(1); 将所述物体(1)保持在所述模具(6; 106)中,同时根据预设的另外的轮廓向所述塑料施加可变的压力,所述预设的另外的轮廓被选择为减小所述塑料中的应力; - 从所述模具(6; 106)中提取所述物体(1)。
