Remploy factories in Derby, Jarrow and Huddersfield, which cut, sew and assemble textile components used in cars, vans and trucks, join factories in Coventry, Birmingham, Stoke-on-Trent, Bridgend, Porth and Abertillery in the division.
The Abertillery factory is also moving to a larger, more modern site where more than £300,000 has been invested.
John Price, Remploy Automotive general manager, says: "We have won a number of new contracts recently and there are more in the pipeline. Bringing Derby, Jarrow and Huddersfield under our automotive umbrella makes a lot of sense.
"Remploy Automotive provides a complete range of services for the industry. We can do everything from helping to design, develop and manufacture head rest covers to sub-assembly, kitting contracts and sequenced deliveries."
