Our mission is to deliver the customer quality parts, on time and at a competitive price.  It is important to us to not just sell products, but also sell solutions. We believe in creating an experience and a culture with our customers.

History

We started in 1999 with three guys in a garage and one injection molding machine.  In the years since, we have grown to a company with over 250 employees, in a 165,000 square foot facility with over 75 molding machines.  The same three guys who started our journey are all still an integral part of our Stone Plastics family.  Their same passion for innovation and customer service exists today as it did when the company first started.
