Our History

Polyshot Corporation Inc. was founded in 1989 in a rented 250 sq. ft. office with two folding tables, two telephones and a list of potential customers that Lou Borrelli, then Polyshot’s first employee and now the General Manager, gathered from telephone books at the local library.

At the time, Polyshot only manufactured heated sprue bushings, but it became evident that expansion into manifold systems was the next step. They soon started creating their first manifolds for their electrical connector industry customers, which were previous Polyshot heated sprue bushing customers.

After growing out of two more rented facilities, Polyshot purchased land and built its first dedicated hot runner facility in 2001. This facility was 12,500 sq. ft. and sat on a 4-acre campus. In 2008, Polyshot embarked on a major expansion, increasing its facility size to 28,500 sq. ft. and renovating its existing facility. The expansion now encompasses Polyshot’s CNC machining and injection molding facilities.

Another opportunity for growth came in 2019 when Redbarn Pet Products, a family-owned manufacturer of healthy dog and cat food, treats, and chews, acquired Polyshot. Post-acquisition, Polyshot continues to run as a separate business, offering its same valuable products and services, under the leadership of Lou Borrelli. Redbarn now proudly boasts over 600 employees.

To this day, Polyshot continues to focus on growing with molding partners worldwide. Contact us for more information about our services and capabilities. For more information about Redbarn visit www.redbarn.com.
