Since 1968, Erie-based LAMJEN has made specialty machined components as a contract precision CNC and manual machine shop. Its unusual breadth combines tight-tolerance work and large-diameter turning with fabrication, assembly, and other finishing support through Custom Group Industries, allowing projects to move from prototype to completed component through one manufacturing network. An in-house quality department supports the work under an ISO 9001:2015-certified quality system.
