Abstract (en)

[origin: EP0245742A1] A shell foil is pulled over a die which has the outer contours of an in-the-ear hearing aid module. This is dipped in the otoplastic material in a negative cast of the earhole. After hardening the blank is taken from the negative cast and the die is removed, leaving the shell foil with the otoplastic so that the electronic components can be inserted in it.
