PoreSeal resins from IMPCO are formulated for the sponge-like attributes of powder-metal (P/M) porosity. The impregnation process is fine-tuned, combining thorough rinsing techniques that are automatically matched to the various densities of the parts produced by P/M part manufacturers. The result is a higher fill (nearly 100%) of complex porosity, thus forming an impenetrable base for subsequent finishing processes. With the IMPCO process, bleed out and its associated problems are virtually eliminated. P/M parts impregnated using the IMPCO process exhibit better machining qualities with reduced chatter, according to the company, resulting in extended tool life of two to five times over traditional processing. IMPCO resins are certified to current military impregnation standards, which form the basis of many automotive industry requirements.
