Today's hearing aids usually disappear almost invisibly in or behind the ear. A good, individually made earmould - also calles otoplastics - ensures that the hearing aid fits absolutely securely and almost invisibly in the auditory canal and is by no means perceived as disturbing by the wearer. The earmoulds are manufactured individually for each patient either in additive manufacturing processes or by machining. The roughness caused by the manufacturing process makes a smoothing after-treatment of the earmoulds necessary.
Gently and effective with disc finishing machines
A gentle and effective surface treatment is necessary to prevent the otoplastics from being damaged during post-treatment and to maintain the geometry precisely. Often it is not possible to do completely without manual processing as a preliminary stage for mechanical post-treatment, because internal geometries are sometimes difficult to achieve with automated processes. Effective machining in the OTEC disc finishing machine reduces manual pre- or post-machining to an absolute minimum. This saves time!
