370 E 16th Street, Greeley, Colorado, 80631, United States


J & B Machine is a contract manufacturer, specializing in Machining and Fabrication value-add services.

As with any company who has been around for the better part of 3 decades, we have identified the most important asset we have, our team! This talented group of individuals is what has enabled J & B to stand the test of time, and build long-standing partnerships with our broad customer base. In order to do so, a team must be guided by a set of values. Our values came to us not by choosing words off a white-board in the conference room. But rather, by observing the daily interactions of our team both internally with each other & externally with our customers and vendors. Those observations defined what our team values:

  • Problem Solving
  • Reliability
  • Flexibility
  • Collaboration
  • Conscientiousness
  • A Growth Mindset

Guided by these values and utilizing the latest in manufacturing technology, J&B excels at adding value to every step of the manufacturing process.

Quoting: We pride ourselves in our DFM (Design for Manufacture) feedback. If our team sees the opportunity to reduce cost, our customer is the first to know. During the quoting process our team utilizes an ERP system which combines up-to-date material pricing as well as time studies accumulated from the manufacturing of hundreds of thousands of parts, ensuring the quote you receive is accurate & competitive.

Scheduling: Our ERP system converts quotes won into fully traceable job travelers, which follow your order from placement to shipment. This system allows full trace-ability on material certs, run reports, quality checks & COC’s (if necessary). Screens throughout the shop give our team real-time updates on scheduling and throughput figures, ensuring your job is completed on time.

Quality: Every job that is released to the shop floor is accompanied with specific, documented steps that outline the process that exact part will follow. Whether it is a structural cart in the fabrication shop, or a titanium breach cap on a CNC lathe; all steps require (backed with documentation) a first article inspection. Throughout the manufacturing of that specific component(s), samples are inspected and documented based off quality requirements from the customer. Once the part(s) is complete, a final inspection (if necessitated) is performed and documented before given the clear to ship. All of this is well documented in our quality manual, feel free to request a copy!
