ETM Manufacturing coordinates metal finishing in Littleton, MA for OEMs, engineers, and buyers who need parts ready to ship, not just ready to machine. We manage a vetted network of finishing partners covering powder coating, painting, plating (tin, zinc, electroless nickel), and anodizing (sulfuric, hard coat), plus chromate conversion, electropolishing, shot peening, sandblasting, passivation, silk screening, and laser etching, all evaluated against our ISO 9001:2015 quality, delivery, and cost standards. Instead of qualifying and managing separate finishing vendors yourself, you get one point of contact and one quality system covering fabrication, machining, assembly, and finishing under a single ETM relationship.
