The invention discloses an infiltration device and method. The infiltration device comprises a heating room (20), a rotary tray (10), a rotary bracket (110), a material box (410), an elevating mechanism and a transmission device (310), wherein the heating room (20) is an annular groove, and the rotary tray (10) is arranged below an opening end at a lower end of the heating room (20); the rotary bracket (110) is installed on the rotary tray (10); the material box (410) is arranged on the rotary bracket (410); the rotary tray (10) and the material box (410) can move upward and downward under the action of the elevating mechanism; the rotary bracket (110) can spin in the annular groove and revolve around a central axis of the rotary tray (10) under the action of the transmission device (310). The infiltration method provided by the invention comprises the steps of charging, vacuum-pumping, high temperature infiltrating, cooling, discharging, etc. The infiltration device and method of the invention not only realize equality of the condition on the position of magnets, but also realize equality of the condition on the heating environment, thereby achieving consistency of the temperature condition necessary for sintered magnets during high temperature infiltration and air-cooling, and ensuring consistency of the performance of the products.
