Abstract

Metal casting is used widely throughout the manufacturing industry, where detection of imperfections is an important aspect of the overall casting process. This work proposes a system based on wireless signal propagation at radio frequency could be used to develop a model for defect detection of a metal part. A proof of concept was constructed of the proposed system to detect the presence of metal inside the propagation channel. The dielectric properties of the sandcasting media were observed, as well as losses and time-delays due to the introduction of a metal object. The measurement setup was validated using set lengths of cables as the propagation channel rather than wireless transmission.
