S7 Technics has begun to manufacture plastic products using vacuum thermoforming. The new method will allow the company to expand the range of items it is able to produce for aircraft interiors.
S7 Technics’ specialists at Novosibirsk’s Tolmachevo airport have been manufacturing plastic components since 2015, with pressure casting techniques used before.
Vacuum thermoforming involves heating a plastic sheet and stretching it around a mold with a vacuum. After the part has cooled, the mold is removed with air pressure.
Currently, vacuum thermoforming produces plastic passenger seat backs that are installed on S7 Airlines’ Airbus A320 family. In the near future, S7 will begin to manufacture other elements of aircraft interiors.
