Tipton-based Steel Parts Manufacturing Inc. has notified the state it expects to lay off 107 employees. The company says the mass layoff is due to “unfavorable business circumstances beyond its control.”

The layoff is expected to affect hourly and salaried employees, and terminations are scheduled to take place during the first two weeks of August.

The layoffs are expected to be permanent.

The company says the affected employees do not have bumping rights.
