Quantum degenerate polar molecules have attracted wide research interest in recent years, for they offer great opportunities to study dipolar many-body physics, ultracold chemistry and new quantum information processing methods. In this talk, I describe the construction of a NaK apparatus aimed at creating NaK dipole molecular.  So far, we have obtained a 10 million atom sodium BEC with lifetime as long as 80s, and a 4 million atom 40K MOT from natural abundant source. We discuss three possible strategies of loading a dual species MOT, which is an important step towards quantum degenerate mixtures.
