One-Stop Shop

We understand time is money, so we have made it our mission to optimize the manufacturing and assembly workflow for our customers. We coordinate our machining with the services of our various outside partners, so from start to finish we can handle it all.

Our years in business have allowed us to build lasting friendships. Our process begins with the procurement of raw material, in bulk, directly from mills and foundries. Once production begins, we manage every step of the workflow including heat-treating, painting, and plating.

We have made it a priority to invest in new equipment and technology to remain on the cutting edge. From the latest CAD and CAM software, to Quality Management Systems and EDI, we make sure we have what we need to support our customer’s demands.

Detail Focused Results Driven

Northern Gear and Machining is ISO 14001:2015 and 9001:2015 certified. We go to great lengths to comply with strict quality standards every single day. These strict standards have led to the design and inception of our home-grown quality management system application. We collect real time data at every step of the manufacturing and assembly processes.

We have invested in the latest, most technologically advanced quality equipment because we understand the cost of quality. From APQP and PPAP to continuous improvement, we deliver quality!
