Thixoforming investigations have been developed, mainly for manufacturing of bulk components. However, the knowledge is very poor regarding the fabrication of thin cross section of alloys. In this research work, an experimental approach has been employed to study the effectiveness of thixoforming process for the fabrication of microchannel for bipolar plates of polymer electrolyte membrane (PEM) fuel cells. A356 alloy in the continuous casting state has been used for this study. Recrystallisation and remelting (RAP) route has been employed to prepare feedstock for thixoforming process. The feedstock with different liquid fractions of 75%-50% were prepared and used for the thixoforming process. The bipolar plates with the thickness of 1.2 mm were successfully fabricated. The presence of any internal defect such as localized porosity was examined using X-ray radiography. The effects of liquid content of feedstock on the formability and die-filling phenomena are thoroughly investigated and discussed. Results showed that at all the applied liquid contents fabrication of bipolar plate is achievable. However, reproduction of bipolar plates is very high at high liquid fraction of 75%.
