Decades of experience backed by uncompromising quality control

Since our inception in 1937, we’ve come to understand the complexities of the product manufacturing process and the critical importance of producing a quality product. Through the decades, we’ve gained proficiency in numerous manufacturing operations related to plastics, metals, and electronics, including CNC machining, extrusion, injection molding, casting, printed electronics, and more. This expertise in product manufacturing allows us to recommend the right methods for your product’s individualized requirements related to production volume, application, cost, and quality.

We understand that experience alone doesn’t always guarantee a quality product. Our commitment to testing, inspection, and quality assurance processes helps us identify and resolve issues quickly. This commitment has earned NMG multiple third-party certifications and accreditations, including ISO (9001:2015 and AS 9100D) and ITAR certifications, as well as NADCAP approval for anodizing.
