This paper descrives the mold releasability evaluation of MAX pahse ceramics. MAX phase ceramics has excellent machinability, wear resistance and corrosion resistance. Therefore, it is considered to be suitable as a mold material in plastic molding. In this study, in order to clarify the applicability of MAX phase ceramics to mold materials, the mold release force between max-phase ceramics and resin was measured. Furthermore, the effect of the surface roughness of the electrical discharge machined surface on the mold release force was investigated. A thermosetting phenol resin was compression-molded on the die-sinking surface of the MAX phase ceramics used as a mold, and the mold release force was measured. For comparison, the mold release force with SKD11 was also measured. The MAX phase ceramics had a smaller mold release force than SKD11. In addition, the mold release force tended to increase as the surface roughness increased in both mold materials. From these results, MAX phase ceramics can be compression-molded with the same transferability as SKD11.
