Abstract
The aim is to manufacture molded tubes for hearing instruments and other hearing devices more cost-effectively. To this end, there is provision for producing a bending mold with the aid of a rapid-prototyping method. An unmolded tube is inserted into the bending mold. Heat is then applied to the bending mold, including the inserted tube, such that after cooling the tube permanently assumes the shape predetermined by the bending mold. Rapid prototyping makes it possible to produce a bending mold for a variety of tube forms quickly and cost-effectively. It is thus no longer necessary to bend the tubes manually, as a result of which the degree of automation can ultimately be increased.

A method for molding a sound canal of a hearing device, comprising:
- creating a bending mold for the sound canal by a rapid-prototyping method;
- inserting a tube into the bending mold;
- applying heat to the bending mold comprising the inserted tube;
- and
- cooling the tube so that the tube is permanently molded to a predetermined shape for the sound canal by the bending mold.
A device for molding a sound canal of a hearing device, comprising:
- a bending mold that has a predetermined shape of the sound canal;
- a tube that is inserted into the bending mold;
- a heating device that heats the bending mold comprising the inserted tube;
- and
- a cooling device that cools the tube so that the tube is permanently molded to the predetermined shape of the sound canal by the bending mold.
