Powder injection molding of silicon carbide: processing …

2016-11-1 · Powder injection molding (PIM) of ceramics and metals dates back to 1932 [1], but has been applied to SiC only sparingly since the 1980s. PIM is a near-net-shape process consisting of four major steps: feedstock preparation, injection molding, binder removal and sintering [2]. Of these four, binder removal is usually the slowest step by far [3].
