Abstract

Pores and other non-sealed parts of metal pieces are sealed by a) subjecting the piece to reduced pressure, b) impregnating with thermosetting resin, stages (a) and (b) being effected in separate containers joined by a pressurised lock, (c) removing surplus resin, and (d) curing the resin sealing the pores of the piece at an elevated temp. Esp. for sealing pores of metal castings with a thermosetting resin.
