In this study, the experimental properties of the fragments of acrylonitrile butadiene styrene and polycarbonate thermoplastics in five levels of pressure, injection temperature, fixed injection rate and fixed maintenance were paid. After testing the components, the data obtained for The software for minifrection 16 has been analyzed using the Taguchi method. The result is that acrylonitrile butadiene styrene is less resistant to polycarbonate due to its non-elasticity, hardness and hardness, and becomes harder to crack during testing.
