Why need to burn off wax before sintering?
Because if the wax is not processed before firing, the paraffin will be melted, lost, volatilized, burned at high temperatures, and the body will lose its bond and disintegrate, and will not retain its shape. 6, the wax removal temperature is usually 900 ~ 1100 °C. If the temperature is too low, there is no certain sintering between the powders, there is no certain mechanical strength, the body is loose, can not follow the subsequent process; if the temperature is high, until completely sintered, there will be serious bond, it is difficult Clean the surface of the blank. Wax body after removal of wax to clean the surface of the adsorbent, and then sintering.
