Objective To study the process performance of PEPSET resin self-hardening sand and furan resin self-hardening sand for cast aluminum parts. Methods The experimental methods of comparing the two kinds of core materials at room temperature and high temperature were compared. Results The technological parameters of the two kinds of resin self-hardening sand were obtained through experiments. The experimental results of the two kinds of self-hardening sand, such as hardening speed, hard permeability and gas evolution, were compared and analyzed. Conclusion PEPSET resin self-hardening sand process performance is good, is expected to become an important direction of development of resin self-hardening sand process.
