We form complex parts for this application to extremely tight tolerances
divider seat shrouds and parts that interface in assembly are textured in the tools during forming. End bays and back shrouds are formed of textured sheet over male tooling.

(762 mm) in length, 18 to 20 in. (457 to 508 mm) in height, and can have 6 in. (152 mm) draw depths. The parts may not look complicated when assembled in a seat, but Cameron says many require sophisticated tools to achieve the shape and functionality required for assembly. Some tools have slides to form undercuts in parts. The shrouds that separate seats, for example, are pressure formed in female tools. Each tool has a sidewall design feature that requires an undisclosed “process enhancement” to assure that the Boltaron sheet forms around the feature properly before vacuum is applied. Otherwise, Cameron says, the material would form a bridge between the feature and the sidewall. Many of the tools are etched with an MT11020 chemical texture that is usually 0.0015 in. (0.040 mm) deep. The centre
Process considerations include whether the seating will be assembled in 2 or 3-seat sets, or installed in a left, right or centre aisle. Some parts for left and right aisle seats differ slightly from each other, and so must be formed in different tools, explaining why there are a large number of part numbers. Multifab orders the sheet in custom colours as specified by each airline. Cameron says the colours are generally special shades of gray, which Multifab and Boltaron develop according to specifications from TIMCO. The company buys the Boltaron sheet in standard or custom sizes depending on part volume. Standard sizes are typically 4 by 8 ft (1,219 by 2,438 mm). Multifab spent a year developing the programme with TIMCO. By the end of 2012, Cameron expects that Multifab will deliver 30 shipsets of seating components. TIMCO Aerosystems is relatively new to the seating market.
Parent company TIMCO Aviation has been involved in aircraft and engine maintenance, repair and overhaul for many years, and in 2002 acquired Brice Seating. TIMCO Aviation dropped the Brice name in April and made the business part of TIMCO Aerosystems. The 3050 FeatherWeight premium economy line is one of the first seating products marketed under the TIMCO Aerosystems brand. “We are enthusiastic about this opportunity,” Cameron says. “TIMCO Aerosystems’ relationship with Multifab has been key to the development of this product line.”
