Castle Plastics was founded by our great grandfather in 1920. He and his bride migrated from Italy to the United States in 1911, and for several years, worked in a local shirt factory. In 1920, he started Castle Button Company. Under the same family ownership, and with many product and location changes, we are still in the plastics business. Materials, tool and dies, and injection molding have been in our family business all these years. We are now preparing to celebrate our 80th anniversary.
