Since 1969, Lewis Plastics has combined technical expertise with a customer-first approach to deliver reliable plastic injection molding and insert molding services. We were founded on a simple belief: making quality parts and building long-term partnerships should always go hand in hand. That philosophy continues to guide everything we do today.
Operating from a 91,000-square-foot, climate-controlled facility in Addison, Illinois, Lewis Plastics supports customers across the U.S. and around the world. Our central location gives manufacturers easy access to a trusted injection molding supplier for both short-run injection molding and full-scale production. Over the years, we’ve expanded our capabilities to include custom plastic injection molding, plastic insert molding, and a variety of value-added services that help customers streamline production. Investments in advanced equipment, such as new Arburg injection molding machinery and in-house 3D printing, reflect our ongoing commitment to flexibility, precision, and efficiency.
We’re known for being accessible, responsive, and easy to work with. Customers know they can talk directly to someone who understands their project and the injection molding process behind it. That level of collaboration builds trust and keeps projects moving smoothly from start to finish. Every molded part is produced to meet ISO 9001:2015 standards in our climate-controlled facility, where quality and communication are part of the same process.
The Lewis Plastics team brings decades of experience in custom injection molding and insert molding manufacturing. Engineers, operators, and project managers work closely with customers to refine manufacturability, control costs, and keep production on schedule. Early collaboration allows our experts to suggest the right materials, tooling methods, and molding processes for each unique part. Customers value that level of involvement – it’s what sets Lewis Plastics apart as one of the most reliable injection molding companies in the Midwest.
The goal has always been the same: deliver quality parts, on time, with transparency and integrity at every step. Investments in equipment, processes, and people ensure Lewis Plastics remains a trusted injection molding partner for decades to come.
