ABSTRACT:
The invention concerns a procedure for the manufacture of an assembled object intended for repeated assembling and disassembling, e.g. a tube (1) with matching cap (4), and a machine for the execution of this procedure. According to the invention the tube (1) and the cap (4) are cast in the same mould (7) end ejected simultaneously and assembled in the exact position they are to have when used. This can suitably be done by first casting the part (4), which at the boundary surface is placed outermost. When it has assumed its final shape, it serves as an independent mould when producing the other part (1). The first cast part (4) thus contributes to the securing of the core system (9, 10, 11) for the other part (1), whereby the wall thickness of this part can be made especially uniform and thin. The machine for the execution of the procedure can thus cast e.g. the assembled cap (4) and tube (1), and it can, therefore, also be adapted to perform an automatic filling, sealing and possibly stamping of the tube.
