What does AMB do?
AMB lacquers the three visible components of the hearing aid:
• The lower section, where all the electronics are
• The cover
• Battery aperture
In order to hold the parts during lacquering and to meet masking requirements, AMB and Tingverken jointly develop plastic fixtures and masks that are unique to every part intended for lacquering. Tingverken builds the injection moulding tools, while AMB moulds the fixtures and masks.
All three parts are lacquered in three layers: primer, base coat and topcoat. The primer is needed to create adhesion to the plastic (otherwise all the colour would peel off). The base coat provides the colour effect (i.e. if the part is red, blue or has a metallic effect). The topcoat protects the underlying layers and also the plastic. You can choose whether this layer should be matte or gloss. Intiga is available in ten different colours, thus also ten different base coats.
After lacquering, the cover and the lower section pass through our fully automatic inspection installation where they’re inspected and packed in bags or on trays. After final inspection, they’re sent to the customer for assembly.
Oticon was formed in 1904 when Hans Demant tried to help his wife, who had impaired hearing. Today, Oticon is a high-tech, multi-billion Kroner group with over 7,000 employees in more than 100 countries. The company is part of a foundation and a percentage of the profits go to support the hearing impaired or to cultural projects.
