Contech Castings LLC is cutting back operations at two Indiana aluminum diecasting plants, affecting the jobs of over 200 workers. Letters from the company’s director of human resources to the Indiana Department of Labor & Workforce Development explain the layoffs are permanent and follow the company’s loss of an automotive supply contract.

Contech Castings filed the two letters with the Indiana agency on February 21, for formal notification of unplanned layoffs at the two plants, in line with the federal Worker Adjustment and Retraining Notification Act. Normally, WARN requires 60-days advance notice of widespread layoffs, though unforeseen circumstances may be cited in certain situations.

Similar letters were sent to workers, listing the types of positions that are affected by the downsizing. At the Auburn plant, 128 positions are being eliminated. At Pierceton, 80 workers are affected.

Most of these positions eliminated concern production technicians and machine operators, but a range of other functions from quality control, electrical and mechanical maintenance, and building maintenance also are affected.

Contech Castings operates four plants, in Alma, MI, Clarkson, TN, and Auburn and Pierceton, IN. There is no indication of changes at the first two plants.

The company is one of five metalcasters owned by the Revstone Industries LLC, a holding company for various manufacturers supplying the transportation and heavy-truck industries.
