NEW YORK — Revstone Industries LLC’s bankruptcy protection filing hasn’t affected die casters Contech Castings LLC and Texas Die Casting, a Revstone spokesman said.

While Revstone Industries has previously been reported as the parent company of Contech Castings and Texas Die Casting—and the companies are listed as subsidiaries on the Revstone website—a Revstone spokesman told AMM Friday that the die casters are actually subsidiaries of Revstone Transportation, "a completely separate entity."

"Revstone Transportation and its affiliated companies are not affected by the bankruptcy," he said. "In fact, Contech is launching new programs and winning new business."

Revstone Industries, a manufacturer of cast and formed metal components, filed for Chapter 11 bankruptcy protection in U.S. Bankruptcy Court in Delaware on Dec. 3. The company is based in Lexington, Ky., but registered in Delaware.

Further details on the relationship between Revstone Transportation and Revstone Industries weren’t available.

Court documents show that General Motors Co. and Sapa Extrusions North America are among the company’s unsecured creditors, listing debts of more than $618,000 and $547,000, respectively.

"We’re monitoring this situation closely, but currently we do not expect any interruptions in supply," a spokesman for Detroit-based General Motors told AMM.

Rosemont, Ill.-based Sapa Extrusions, a division of Stockholm, Sweden-based Sapa AB, wouldn’t comment on the bankruptcy filing.

A creditors’ meeting has been scheduled for Jan. 9 in Wilmington, Del.
