high deformability, low stiffness), the functional accuracy requirements are much lower than for metals in order to economically manufacture moulded parts with sufficient dimensional accuracy. Based on particular properties of the plastics (e. In comparison to metal materials, significantly larger deviations in respect to dimension, form and location are usually to be expected when applying and manufacturing the moulded parts.
