Custom Sheet Metal Enclosures
Lee Manufacturing designs and produces custom sheet metal enclosures tailored to security, fire, and telecommunication needs. Our enclosures meet NEMA, UL, and FM standards, ensuring protection against dust, moisture, and electronic interference. By collaborating with client engineering teams during design, we ensure rapid adaptation to market changes while reducing production costs through efficient tooling and economies of scale.
Precision Fabrication
Our precision fabrication leverages high-speed punch presses, CNC forming stations, and welding centers to produce high-volume, high-speed enclosures. The process uses commercial-quality steel and Total Productive Maintenance to minimize downtime. Redundant machinery ensures continuous production, while in-house tooling design allows rapid adjustments for evolving client requirements.
Powder Coating
Lee Manufacturing applies durable powder coatings resistant to chipping, scratching, and fading. The electrostatic process ensures even coverage, with seven reclaim modules reducing material waste. Two automated powder lines include six-stage wash systems for corrosion protection, followed by curing ovens and environmentally controlled application rooms to guarantee a high-quality finish.
Hardware Insertion
Post-welding hardware insertion uses four 6-ton pemserter machines to install fasteners into steel enclosures. This service accommodates custom specifications, ensuring secure and precise integration of components like brackets, hinges, and mounting hardware for functional readiness.
Warehousing Programs
Our warehousing solutions include Kanban and blanket order programs to streamline client inventory. By holding stock under predetermined schedules, we reduce floor space needs, carrying costs, and purchase order complexity while enabling just-in-time delivery via EDI integration.
