Explain why coining can be used to make more complicated shapes than can conventional sintering
What will be an ideal response?
In conventional sintering the shape of the part is determined by the preforming mold. Since the main purpose of preforming is to eliminate voids and compact the material, high pressures are required and the ability to press the powdered material into complicated shapes is compromised. In coining, the part is placed
into a mold when the part is in a softened state. Therefore, pressing into a detailed shape is much easier.
