Abstract
This paper proposes a method to produce silicone rubber moulds for low-pressure wax injection moulding. Wax spilling is one of the most troublesome problems during the wax injection moulding process. From the point of view of green manufacturing, the optimal processing conditions in the wax injection moulding process were investigated using the Taguchi method. The experimental results revealed that the most influential factor affecting the weight of spilled wax is the injection time. The optimal processing conditions in the wax injection moulding process are an injection temperature of 82 deg C, an injection time of 2 s, an injection pressure of 0.6 kgf/ cm2 and a mould temperature of 60 deg C. 21 Refs.
