Requirement:

• 2 fully worked prototype castings

Solution:

• design of a casting mould with complex core geometry
• conventional manufacture of the outer mould
• laser-sintering of the one-piece sand cores using EOSINT S 750

Result:

• perfect switching properties due to tool-less core manufacturing without de-moulding angles
• series production (200 pieces/year) was switched over to laser-sintered cores to keep the geometry benefit
• simplification of the (conventional) casting mould could be achieved, as parts of the outer contour have been integrated in the core
