Our Core Metal
Fabrication Capabilities
Everything you need.
All under one roof.
We don’t farm out the hard stuff - we built a team and a facility to handle it ourselves. That means shorter lead times, fewer headaches, and more reliable results for OEMs nationwide.
Laser Cutting
High-speed 6kW fiber laser cutting for sheet sizes up to 79" × 158", delivering tight tolerances, clean edges, and superb repeatability for complex parts and OEM needs.
Metal Forming
Offline-programmed press brake forming with a broad tooling library for precise bends, dependable repeatability, and efficient setup — ideal for low- to mid-volume metal parts manufacturing.
Welding
Manual and robotic welding performed by certified pros — qualified up to 1" thick — for clean, consistent welds on complex weldments.
Machining
Tight-tolerance machining (milling and turning) integrated with fabrication for fewer setups, better accuracy, and faster throughput from prototype to production.
Assembly
Turnkey assembly for subassemblies and component integration — all in-house for shorter lead times, lower total cost, and stronger QA traceability.
Industries We Serve
Built for precision and performance in high-demand environments.
LMI supports a wide range of OEMs across industries. We deliver metal fabrication solutions engineered for speed, accuracy, and long-term reliability. Whether you need custom metal fabrication or full contract manufacturing, our team ensures every part meets your performance standards.

The Value of In-House Metal Fabrication
In-house metal fabrication streamlines production by keeping every step under one roof, from laser cutting and metal forming to welding, machining, and assembly.
When critical processes stay connected, projects move faster, communication stays clear, and quality stays consistent from start to finish.
For OEMs, this means greater control over timelines, costs, and part performance—key advantages that drive repeatable, high-quality results in every production run.
