ABSTRACT:
The disclosure relates to a binder, and the method of formulating the said binder, which is suitable for shaping parts from metallic and/or ceramic particles by injection molding. The binder comprises materials that are mainly thermoplastics, each of which having a percentage that is determined by its thermogravimetric analysis (TGA) profile and a weight loss versus highest binder removal rate from a green body by progressive heating. The removal of this binder from the green body is performed within a much shorter period of time than those published in the prior art. An example binder comprises 40-70% HDPE, 18-30% Paraffin wax, 10-25% microcrystalline wax and 2-5% stearic acid. Another binder comprises 35-65% PP, 23-35% paraffin wax, 10-25% microcrystaline wax and 2-5% stearic acid.
