Method and tool for forming long and thin deformable member for hearing aid

摘要

A tool ( 20 ) and a method for shaping an elongated deformable member for a hearing aid ( 1 ). The tool is manufactured using a rapid prototyping process. The tool comprises a first holding means ( 21 ) for a first end of the elongated member, a second holding means ( 31 ) for holding a second end of the elongated member, and positioning means ( 26,28 ) for positioning and holding intermediate parts of said elongated member between said first end and said second end in a fixed desired shape. The shaping a of the deformable elongated member comprises the steps of placing the first end of the elongated member in a predetermined position, positioning said intermediate parts of said elongated member in a predetermined position, placing the second end of the elongated member in a predetermined position, heating said elongated member, and cooling said elongated member.
