MANDREL, AND ORIFICE PLATE FOR ELECTROFORMING USING THE MANDREL

Japanese Patent JP3851789

B2

PROBLEM TO BE SOLVED: To provide a mandrel capable of electroforming an orifice plate with non-uniform thickness, and a method therefor.
SOLUTION: This orifice plate has a thick boundary 32 surrounding a thin orifice area 34. The mandrel has a metal layer 4 on a substrate 6. The metal layer 4 has a first electroformed surface 18 which is electrically insulated from a second electroformed surface 19. The boundary 32 and the orifice area 34 are substantially electroformed on the first and second electroformed surfaces 18 and 19. The mandrel 2 has a patterned insulation layer 8 on the metal layer 4 for electroforming an orifice 30 in the orifice area 34. In the electroforming process, the first electroformed surface 18 is used for electroforming the boundary 32 while the orifice area 34 is not electroformed. When the metal is deposited on the boundary 32, the first electroformed surface 18 and the second electroformed surface 19 are electrically connected to each other, and successively, the orifice area 34 is electroformed on the second electroformed surface 19.
