Method and device for characterizing a deformation part made of an entropy-elastic material

摘要

The present invention relates to a method and a device (110) for characterizing a deformation part (112) made of an entropy-elastic material during and / or after production of the deformation part (112) in a forming process. The method has the following steps: a) providing at least one tool (114) adapted for the forming process, wherein the tool (114) has at least one cavity (116) for receiving an entropy-elastic material, and wherein in the tool (114) further comprises a test device (140) for providing and is integrated for the detection of ultrasound, being provided by the tester (140) guided ultrasonic waves; b) introducing a material under pressure into the cavity (116) and maintaining the pressure and a temperature for a period of time such that the forming part (112) comprising the entropy-elastic material is produced; and c) applying ultrasound to the cavity (116) during the period and / or after the period of time provided by the testing device (140) and detecting the reflected ultrasound by means of the testing device (140), whereby the characterization of the forming part (112 ) he follows. The method and the device (110) enable a simple in-situ determination of properties and / or dimensions of entropy-elastic materials, in particular of formed parts (112) made of elastomers or heated entropy-elastic thermoplastics, during and / or after production of the forming part (112). in a forming process.
