Scalable. Streamlined.
American-Made.
Inpres is a vertically integrated plastic injection molding company based just northwest of Chicago. Inspired by design we bring products to life profitably through high-volume, high-efficiency manufacturing. We offer everything from design and development to mold building, molding, decorating, assembly, warehousing, and distribution.
We serve a wide range of industries with both proprietary and custom-injection molded products. Our facility is built for scale and speed, and our process is driven by lean principles and automation — delivering American-made quality with competitive lead times and pricing.
Our History
Inpres began as a contract molding operation to offset open machine capacity from other proprietary products. Over the years, we’ve grown steadily, expanded our capabilities, invested in new technology, and built long-term relationships with our customers nationwide.
Our team delivers steady performance that exceeds industry benchmarks. We’ve grown our employee base faster than the industry average, increased revenue per employee, and maintained consistent year-over-year growth—all while staying true to our core commitment to quality and customer service.
