Inflator pump cam manufacturing method

The invention relates to the technical field of manufacturing methods of auxiliary component and parts of an inflator pump, in particular to an inflator pump cam manufacturing method. The inflator pump cam manufacturing method can reduce cost and includes the following steps of (1), powder production, wherein the powder comprises, by weight, 1%-2% of selected Ni, 0.5%-3% of selected additives, a quantity of selected plasticizers and the balance Fe, and the additives comprises one or a mixture of C, Cu, Si, Mn, P, S and Zn; (2) compression forming, wherein the powder is compressed in a needed shape with a mold as a fundamental shape at the pressure of 400 MPa-600 MPa; (3) sintering, the formed powder is sleeved with a copper sleeve and sintered in a high-pressure mesh belt furnace or a vacuum furnace, the temperature is selected to be 1120 DEG C-1130 DEG C, and the time is selected to be 40-60 minutes.
