More than 250 jobs are being created as three business expansions come to fruition on the same site.
Lear Corporation, TRW and Expert Tooling and Automation, which each operate in the automotive supply sector, all began work last year to increase the size of their facilities at Rainton Bridge Industrial Estate in Sunderland.
Foam seating supplier Lear Corporation is creating more than 100 jobs with an extension which will allow it to double production to more than 600,000 car seats annually.
Neighbour TRW has received assistance from Sunderland City Council and £1.95m from the Regional Growth Fund to double its factory floor space, while Expert Tooling is preparing to move into a new facility at Rainton Bridge in either May or June.
Sunderland City Council leader Paul Watson said: “Sunderland is a national – and international – force in the automotive sector and the expansions now approaching completion at the council’s Rainton Bridge Industrial Estate demonstrate how important this industry is to our local economy.
“TRW, Lear and Expert Tooling chose Sunderland as a location based on the city’s strength and depth in this sector and the excellent workforce we have locally. We have been proud to help, support and advise on their growth.
“This is a sector that is continuing to expand in the city, thanks to our strong supply chain, excellent location and logistics and the groundbreaking work taking place in the field of electric and environmentally-friendly vehicles. The city council is keen to work with other automotive businesses seeking support to expand in Sunderland and businesses looking for a new base for their automotive operations.”
