Abstract
1,161,179. Making pistons. MAHLE K.G. 18 Sept., 1967 [1 Oct., 1966], No. 42342/67. Heading B3A. Method of making a light-metal piston having a closed annular coolant &c. duct in its head comprises supporting with pins 3 of highmelting-point material, e.g. alloy steel, an insert 2 in a mould into which light metal is cast about the insert to form a substantially solid cylindrical blank, withdrawing the pins 3 and replacing them by plugs (6), Fig. 2 (not shown), of light metal, e.g. pure aluminium, pressing the blank to form a hollow piston 7, Fig. 3, and dissolving the insert with a solvent which does not attack the piston metal. The holes left by withdrawing the pins 3 may be filled in the copper insert with copper &c. pins (8); those in the light metal may be bored out for larger, light-metal pins (6) shorter in length than the holes. The pins (6) fill the holes during the pressing operation. Reference has been directed by the Comptroller to Specification 1,081,595.
