Development of Salt Core Use Alternative in Aluminum Alloy Casting Parts

For creating complex geometric shapes in the cast part, salt was used to produce core instead of sand which is thermo-chemical or chemical process using resin as a binder.In salt core casting, the efficiency will be increased by reducing the core gas-induced errors in the part. The harmful effect on the environment will be reduced with the absence of odor and smoke from the core gas.Using water in salt core breaking instead of mechanical impact and vibration during sand core breaking will bring benefits such as eliminating the noise source and using less energy. By eliminating the dust generated during sand core breaking, its harmful effects on the environment will be reduced. Since the salt core can be dissolved in water and removed from the piece without any residue, there will be no problem of sand remaining in the sand core from time to time.
