Low pressure injection molding (LPIM) method in this paper is investigated as a method of forming alumina parts. This is one of the methods of making engineering ceramics with complex shapes and high dimensional accuracy. In this method, a binder system (paraffin wax + carnuba wax) was used as a plastic agent for easy formation of alumina particles. Different parameters such as feedstock temperature, injection pressure, injection time, mold temperature, etc. are effective in shaping ceramic parts by LPIM. The study of these parameters and the selection of their optimal value are discussed in this article. The optimum injection temperature was in the range of 90-90 ° C, the optimum pressure was in the range of 4-6 bar, the injection time was in the range of 10-15 seconds for a cylindrical shape with dimensions of 20×125 mm (D × H).
