Manufacturing technique of powder metallurgy

摘要

The manufacturing technique for powder metallurgy of the invention includes the steps of: mixing ceramic powder with binders, fillings or lubricants for casting a body; forming a microwave-absorbent body using molding, extrusion, forging, injection or doctor blade; placing the body into a microwave oven for heating and debinding; placing the half-finished product after debinding in a sintering oven for sintering the debinded half-finished product; and finally obtaining a finished product after sintering and temperature lowering.
