An acetal copolymer containing mineral oil, formulated and made in-house by Railko, has superseded PU for an injection moulded steering bush for Ford's Escort, Granada, and Scorpio Models. The PU item was prone to problems of stick-slip, necessitating the addition of oil to the assembly, and an expensive rubber gaiter to prevent seepage. Railko's material, coded ~~80, has eliminated the need for oil, and allowed the use of a cheaper gaiter.

A printer-head chassis for Unisys Burroughs in France, originally in die cast aluminium with bronze and steel components - 48 in all - has been redesigned with only 10 parts using mouldings in a PTFE-filled, glass-reinforced Lexan polycarbonate. The PTFE is used to overcome frictional problems and it is the first time this Lexan material has been used in Europe.
