S7 Technics finds new method to produce plastic components
S7 Technics, Russia’s maintenance, repair and overhaul (MRO) services provider has begun to manufacture plastic products using vacuum thermoforming
The new method will allow the company to considerably expand the range of items it is able to produce for aircraft interiors.
S7 Technics’ specialists at Novosibirsk’s Tolmachevo airport (IATA: OVB) have been producing plastic components since 2015, with pressure casting techniques using before. Now production of serial parts using the new vacuum thermoforming method has been organized.
The technology of vacuum thermoforming involves heating of a plastic sheet, which is stretched over the mold with a vacuum. After this, the molded part is allowed to cool down. Then it is pushed out of the mold with excessive air pressure.
“Currently, using vacuum thermoforming, we produce plastic passenger seat backs. They are being installed on S7 Airlines’ Airbus A320 family of aircraft. In the near future, we will begin to manufacture other elements of aircraft interiors. We get all consumables for plastic components from leading international manufacturers,” Stanislav Aganin, head of the Part 21G production department at S7 Technics’ Novosibirsk base, explains.
The design of new plastic production was carried out by the Design Bureau of S7 Technics’ Novosibirsk base. All materials used in the process passed the necessary fire tests carried out the company’s own laboratory. The laboratory’s activity is certified by the National accreditation body in the ILAC-MRA system (International Laboratory Accreditation Cooperation).
Plastic parts manufacturing involves 29 specialists. During four years of its activity, more than 15,000 plastic products have been manufactured in the component production workshop. They are used by such airlines as Alrosa, Ural Airlines, Air Astana, Red Wings and S7 Airlines.
S7 Technics also manufactures certified metal and plastic production, soft stock (fabric and leather, including laminated, covers, as well as curtains, bags, pockets) and placards.
