Since we purchased our first injection molding press 35 years ago, we at Custom Plastics have been committed to providing our clients with unmatched quality injection molded parts at affordable prices. We are not always the lowest priced option, but our 99.9% on-time delivery rate and our 99.8% part acceptance rate continue to provide the lowest possible lead times, ultimately leading to a higher bottom line for our valued customers. Over the years we have continued to add to our capabilities by installing additional molding presses ranging from 55 to 720 tons, which has allowed us to expand our services to a wide variety of markets. Our commitment to producing high-quality parts and delivering those parts ‘on-time every time’ has helped us gain the trust of our valued customers and the plastics industry as a whole. We are proud to have become one of the Midwest’s premier suppliers for injection molded parts and we look forward to learning more about your next project and helping to see your business continue to grow.
