The new owner of Brillion Iron Works says it will start laying off workers at the foundry in eastern Wisconsin in November.
Metaldyne Performance Group announced last week it plans to shut down the foundry. More than 300 people will lose their jobs.
The Wisconsin Department of Workforce Development said Monday it was notified the layoffs will begin Nov. 11. About 340 workers are affected.
MPG has said workers in Brillion will be offered a chance to relocate to other MPG foundries "as opportunities exist."
The Southfield, Michigan, company bought the Brillion foundry from Accuride Corporation for $14 million on Sept. 2.
