ABOUT ENGINEERING INDUSTRIES

Engineering Industries (EI) is a 100% employee-owned plastic injection molding manufacturer located in Verona, Wisconsin. Our company operates with a balance of technical expertise, automation, and steady collaboration. Every molded part reflects the care, precision, and accountability of people who take ownership in their work.

 

Built on Engineering Expertise

Technical skill defines every part of our operation. We specialize in custom plastic injection molding solutions for intricate components. A press range of 40 to 250 tons supports high-mix, specified-volume molding using electric and hydraulic presses. Automated systems, robotics, and data-driven controls keep production efficient and repeatable while maintaining flexibility for frequent changeovers.

Expansion That Reflects Commitment

Our team continues to invest in growth, people, and technology. The most recent expansion added production space, equipment, and an advanced closed-loop process water system. With greater molding capacity and faster turnaround, we can support more custom injection molding projects and larger production runs with the same focus on quality and precision.

Quality Commitment

Quality is not treated as a separate initiative. It is part of how EI operates every day. Our quality commitment is guided by the same principles that shape our culture and customer relationships: excellence through integrity, innovation, and superior service.

An ISO 9001-certified quality system supports documented processes, traceability, and consistent verification throughout production. Automation strengthens that system through real-time monitoring, repeatable process control, and stable production methods. Operators, engineers, and quality personnel work together to keep projects on track and parts aligned with print, appearance requirements, and functional expectations.
