About Granger Plastics Company

Granger Plastics Company was founded in September 1994, by rotomolding veteran, John Grimes. His father, John Grimes Sr. was noted as one of the original architects of the rotomolding industry back in the 1950’s.

Upon starting the rotational molding company in Sharonville, Ohio in 1994, the company quickly experienced large growth for custom rotationally molded products inside of its first 2 years. In 1996, the company required additional manufacturing space, so Grimes and his business partner chose another Cincinnati-Dayton area suburb of Middletown, OH.

In 1998, Grimes and his business partner decided they needed additional expertise for new found opportunities, so they brought in another partner. Jim Cravens, a former co-worker from John’s rotomolding history would join the Granger Plastics team. Jim would be an integral part of Granger’s continuing growth, taking the company to new levels and providing new innovative solutions for a plethora of new rotomolding customers.

Granger Plastics Company continued to grow, developing a number of rotationally molded plastic solutions for a number of OEMs and internationally recognized industry leaders. In 2002, Grimes would decide to retire, selling his stake in the company to Jim Cravens and Grimes’ business partner, Jack Cobb, a well-known entrepreneur who was active in owning a number of wildly successful businesses and developments throughout the World, including one of the World’s largest privately owned restaurant equipment manufacturing companies.
