It may be of any shape or size as long as it is integrated with the metal shell and has a shape and size that are satisfactory for improving the adhesive strength between the metal shell and the packing. It is most preferable that the metal protrusion has a conical shape, so to speak, an undercut shape, in which the diameter gradually increases from the joint with the metal shell to the tip of the protrusion, from the viewpoint of improving adhesive strength. Further, the mutual spacing between the metal protrusions on the shell surface may be, for example, 10 inches or more, preferably 40 to 50 inches.

く。(Function) In the electroforming mold of the present invention, on the packing side surface of the metal shell,
Because the metal protrusions are formed integrally with the metal shell, in other words, the protrusions on the surface of the metal shell and the recesses on the surface of the packing material with a shape corresponding to the slippage are engaged with each other, so the anchoring effect , the bonding strength between the metal shell and the packing material becomes significantly high. Therefore, the electroforming mold of the present invention has sufficient resistance to peeling of the metal shell and packing material even if high heat or strong impact is applied during base production and subsequent use (product molding). . Since the protrusion and the shell are integrated, this resistance against peeling works to a satisfactory degree even if the thickness of the metal shell is thin.

#), it is also possible to attach metal granules of an appropriate size to the surface of the metal shell with an adhesive after electroforming.
In this method, there is a risk that the formed metal protrusions may come off more easily than the metal shell, and the effect of improving the bonding strength between the metal shell and the backing cannot be expected to be sufficient. Installation is a very troublesome task. On the other hand, 1
In the manufacturing method of the present invention, the above metal protrusions can be formed by simply attaching a granular magnet to the surface of a metal shell during electroforming and then further electroforming, and the method is extremely simple and easy. .
