Our Story
Established in 1974 as Wise-Hamlin Plastics, we began our journey with a simple vision: to provide exceptional plastic injection molding services to manufacturers in need of reliable, high-quality production partners.
Over the decades, we've evolved into Wise Plastics Technologies, expanding our capabilities to include liquid silicone molding, comprehensive contract manufacturing, and value-added secondary operations. Today, we operate three state-of-the-art facilities with over 350,000 square feet of purpose-built manufacturing space.
Our strategic location in the greater Chicagoland area, with headquarters in St. Charles, Illinois, positions us perfectly to serve customers across North America and beyond. Just 30 minutes from Chicago and O'Hare International Airport, we provide excellent logistics and accessibility for our global customer base.
