Process Parameter Experiments on Vacuum Casting Using a Silicone Rubber Mold for ABS Plastic Parts

Silicone rubber mold is one of soft mold processes for rapid tooling. Based on a master pattern, it can be used for casting the materials of wax, plastic, and low-melting metals directly during a short developing time, very suitable for sample fabrications. This paper conducts vacuum casting experiments by Taguchi’s method to derive the optimal parameter selections on ABS plastic vacuum casting using a silicone rubber mold. The factor that affects pouring characteristics maximally is the mold vacuuming time.
