From a one-person grinding shop to a precision CNC and prototype facility — built on partnerships, refined through continuous improvement, and powered by a team with over 75 years of combined manufacturing experience.
From a one person shop in Capron to a multi machine precision facility in Rockford. Every milestone has been about doing the next thing better.
Founded as a one person grinding shop in Capron, IL.
Became RG Manufacturing — added CNC, prototype work, and a quality control program.
Expanded into prototype and machine repair, broadening our customer base.
Relocated to our current Rockford facility — more capacity, more capability.
E2 Shop System launched — inventory management and blanket orders for customers.
ISO 9000 compliant and pursuing full certification. The journey continues.
As a one person shop in Capron, IL called Double E Grinding, the shop transformed into a CNC and prototype facility with a quality control program in 1995 — and became RG Manufacturing and Machining, offering inventory programs designed to meet customer needs and deliver quality parts on time.
In 2007, RG acquired Opt Tool, which was well positioned in the prototype and machine repair part business. RG was relocated to our current facility in Rockford, IL in 2008.
At RG, we always strive for continuous improvement in manufacturing technology. We believe training is absolutely essential to our mission — which is why we sponsor the RRVTMA Apprenticeship Program, with eight machinists having completed the apprenticeship and become Journeymen.
In 2018, RG implemented Enterprise Resource Planning (ERP) software, which increased our capability for inventory management and gave us the ability to hold inventory for customers using Blanket Orders with specified releases.
We all believe our customer comes first — and we value the partnerships we have formed through the years.
We offer support through every stage of a part’s life: prototype, engineering samples, pre-production, and full production. That support includes Inventory Management, Contract Management, Kanban, Delivery and Pick-up Service — built around how your team actually works.
Through our network of certified suppliers and advisors, we provide sourcing opportunities to optimize price, lead time, and inventory. We have experience with start-ups, off-shoring, and reshoring.
Whether it’s a prototype, a short run, or a long-term inventory program — we’d like to hear about your project.
