Abstract With the development of information technology， the inductor industry is booming. Integral forming inductor is widely used because of its many advantages. But in the compaction process， due to the friction of powder， the pressure loss and other issues， the density distribution is not uniform， which directly affects the performance of the components. The warm compaction process has many advantages， such as high green density and sintered density， high green strength， low ejection force， little elastic aftereffect， so the process has attracted much attention in recent years. Effect of temperature， pressure and lubricant on the inductor density was studied， so as to solve the problem of nonuniform density distribution of integral forming inductor. The forming process was evaluated by calculating the difference between the inductor overall density and local density， and the best parameters are as follows： compaction temperature of 150 ℃， Apex lubricant content of 0.3% (mass percent) and compaction pressure of 800 MPa. Thus the integral forming inductor with density of 7.23 g/cm3 and local density difference of 0.02 g/cm3 is achieved.
