Abstract
The combination of a die simulating the outside contour of an in-the-ear hearing aid module with an over-shell end cap which is seated on a die connector or neck projecting through a proximal hole of the over-shell is immersed into fluid otoplastic shell material which is situated in the negative of an ear impression. The hardened blank is proximally and distally freed of otoplastic shell material and is also proximally freed from the cap such that the die or a remaining part of the die can be easily and unproblematically removed in distal direction, so that the over-shell with the otoplastic shell material seated thereon remains as a finished otoplastic shell.
