Abstract: A method is provided for teem-welding metals, preferably light metals, particularly aluminium and its alloys, in which the metal, during its introduction into a casting mould, is caused to form one or more metal jets which are directed as far as possible at right-angles to and concentrated against the surfaces to be melted of the workpiece or workpieces. There is used a mould of such volume and with such an arrangement of the workpiece or workpieces therein, that the desired melting is achieved with that quantity of metal which, as the process proceeds, accumulates in and fills the mould, which quantity constitutes all the metal introduced into the mould.

Abstract: A composite mold construction for casting on the connector straps, posts, and terminals for lead acid electrical storage batteries according to the techniques of U.S. Pat. Nos. 3,718,174 and 3,802,488 wherein the mold cavity areas are alternately heated by direct flame on one face and then chilled by a coolant on their opposite face to freeze metal in the cavities without freezing molten metal flowing in adjacent flow channels. A plurality of mold cavity partition inserts are arranged to be interchangeable in the main mold assembly to enable a single mold assembly to be utilized for several arrangements of battery cells, strappings, and terminals. Thermal distortion of the mating parts is minimized to maintain the cavities free of leaks by interfitting under cuts and pinned or otherwise keyed couplings between the relatively thin inserts and the more massive primary portions of the mold assembly.

Abstract: There is disclosed a mold assembly for casting posts and plate connector straps onto stacks of plates of lead acid type batteries wherein molten metal is circulated through one or more channels in the assembly and selectively damned to overflow into adjacent mold cavities. Cycle time and properties of the posts and connector straps are improved by constructions which impart a large thermal mass to the channel walls and a small thermal mass to the mold cavity walls. Thermal isolation of the mold cavity walls from the channel walls further enhances these conditions whereby the molds can be elevated in temperature prior to the casting operation and rapidly cooled during that operation. Cooling of the post mold cavities earlier and at a faster rate than the strap mold cavities increases post strength. A mold frame construction containing the molten metal flow channel and one or more inserts for the frame provide the desirable thermal properties while lending flexibility to the apparatus.
