A self-righting inflatable life raft comprises a raft body having inflatable side walls and a floor located therebetween. The apparatus includes: a means for forming a molten material comprising at least one of a metal and an alloy; a means for pouring the molten material; a mold assembly comprising a solid shell having a face coat interposed between the solid shell and molten material; and a heater assembly for maintaining the solid shell at a temperature. The insert may be asymmetric across a lateral axis and have forward and rearward regions and have a pair of elasticized standing cuffs, a fastener component, and an insert indicium disposed thereon. The conductive carbon coating is then optionally fixed on the nonconductive surface and dried. The fasteners can be \u201cD\u201d shaped and configured to rotate through the adjunct material when the fastener rotates from the end effector into tissue. A test program is generated according to the wiring pattern of the cable and the wire list.
