生产接近最终形状的部件增加了对工具正确尺寸的需求。在内部压力较低的工艺中，部件的尺寸反映了模具中模腔的尺寸，但在内部压力较高的工艺中，模具在模具中的变形会导致最终部件的形状不正确。考虑到由于高内部压力导致的模具变形，必须校正模具型腔的尺寸。模型材料技术适用于测量内部压力，但迄今为止，只有一个传感器测量正常的压力。(C)2001 Elsevier Science B.V.保留所有权利。
Production of components close to the final shape increases the demand for correct dimensions of tools. In processes where the internal pressure is low, the dimensions of the component reflect the dimensions of the die-cavity in the tool, but in processes where the internal pressure is high, die deflection in the tool causes incorrect shape of the final component. The dimensions of the die-cavity have to be corrected taking into account die deflection due to the high internal pressure. The modelling material technique is suitable for measuring internal pressure, but so far only a transducer to measure normal pressure has been available. (C) 2001 Elsevier Science B.V.
