Abstract

The gating system was designed for the thin-walled electronic case frame casting. The process was simulated and the optimal process was determined by the simulation software. The trial production of the casting was completed by 3 D printing sand mold casting process. The castings were well formed with the minimum wall thickness of 2.5 mm

of which the dimensional accuracy and internal quality could meet the requirements.
