Abstract: This invention relates to apparatus and methods for molding battery group straps. Molding apparatus, generally indicated at (10), includes a centrally cooled mold block (11) which defines two laterally displaced sets (12, 13) of longitudinal spaced mold cavity (14) and respective lead feed block (15) and (16) having appropriate feed channels. A sensor, in the form of an electrically conducting rod (25), is disposed so that its tip forms one part of the bottom of the mold cavity (14). This can detect as soon as lead enters into the cavity and that detection is used to control the pour time for the lead to a predetermined period, so that the lead entering the cavities is of a constant quantity on each cycle.
