Abstract
A method of providing a molded plastic component for a bipolar battery comprising a metal substrate subject to warpage upon molding to form a plastic frame about the periphery of the metal substrate, and the molded plastic component itself, comprises preheating the metal substrate and then injecting a plastic having shrinkage characteristics which match those of the heated metal substrate so as to provide a plastic frame wherein the plastic-metal interface has a reliable seal and is free from residual stresses.
