    摘要: A method for compression-moulding a dose of plastics in a mould having a first forming arrangement and a second forming arrangement comprises the steps of: moving the first forming arrangement towards the second forming arrangement at a speed that is variable according to a preset profile, the preset profile being so chosen as to apply reduced stress to the plastics, in order to obtain an object from the dose; maintaining the object in the mould while applying variable pressure to the plastics according to a preset further profile, the preset further profile being so chosen as to reduce the stress in the plastics; extracting the object from the mould.
