About Us

The Mission Statement of Cosar Mold, Inc:

To supply our customers with a proven track record of excellence in all our affairs.

To ensure our employees of a safe workplace environment while maintaining a steady growth for a prosperous future.


The Name “Cosar” actually stands for company of Steve and Al Rastetter. Cosar Mold, Inc. was started in 1985 by Steve and Al Rastetter in the basement and garage of their house with the idea of providing the Plastic Industry with a source for mold finishing. Three years later Cosar Mold was rapidly growing and had expanded to a facility on Walnut Street in Kent, Ohio with five full time employees and also had become Incorporated. In 1995, Cosar Mold, Inc. purchased 2.6 acres located off of Mogadore Road in the Commerce Industrial Park in Kent, Ohio and built a 15,000 square foot building, where they now reside. In 2001, Cosar Mold, Inc. added Jerry Johnson on to the team as a Partner. With the collaboration of all the employees, Cosar Mold, has continued to evolve and grow as the leaders in mold repair and revisions for the plastic industry.
