About IMT Precision
Founded in 1994 in Hayward, California, IMT Precision specializes in manufacturing large, complex metal components and assemblies for the most demanding applications in aerospace, defense, semiconductor, space, energy, and biomedical.
30+ Years of Precision at Scale
IMT Precision has operated out of Hayward, CA since 1994, growing from a small job shop into a 50,000 sq. ft. facility with one of the largest CNC envelope capacities on the West Coast — up to 201" x 134" x 42" of travel. Our 9 core capabilities span precision CNC machining, sheet metal fabrication, TIG & MIG welding, inspection & metrology, assembly & integration, Ultra High Vacuum systems, large envelope machining, rapid prototyping, and engineering services. We hold tolerances to ±0.0001" across ferrous, non-ferrous, and exotic alloys including aluminum, stainless steel, titanium, Inconel, PEEK, and G10.
Trusted by the Companies Pushing Boundaries
Our customers include Tesla, Sandia National Laboratories, Maxar, Lawrence Livermore National Laboratory, Applied Materials, SLAC, Brookhaven, Thermo Fisher, and a growing roster of commercial space startups. These organizations come to us because we combine the precision of a specialty shop with the equipment footprint of a large-format facility. From one-off research apparatus to production vacuum chambers for semiconductor OEMs, we deliver complete, inspected assemblies backed by ISO 9001:2015-certified quality processes, full material traceability, and CMM-verified dimensional data.

Frequently Asked Questions
Large Envelope Capabilities
What is large envelope machining?
Large envelope machining refers to CNC machining of oversized parts that exceed the capacity of standard machine tools. IMT Precision operates some of the largest CNC mills in the Midwest, with travel ranges up to 79 x 32 x 30 inches on a single setup, allowing us to handle structural components, large weldments, and oversized assemblies in-house.
What size parts can IMT machine?
Our CNC machining centers accommodate parts with travel envelopes up to 79 x 32 x 30 inches. For even larger weldments and fabrications, our facility includes overhead cranes and rigging capacity to handle heavy components through full-cycle manufacturing.
Can you machine large weldments after welding?
Yes. Post-weld machining is one of our core competencies. We regularly machine critical surfaces and features on large welded structures to achieve precision tolerances, ensuring proper fit and function in final assemblies.
Do you handle turnkey large-part projects from raw material to finished assembly?
IMT provides full-cycle manufacturing, from material procurement and cutting, through welding and precision machining, to final assembly, inspection, and shipping.
Tolerances and Quality
What tolerances can IMT hold?
Achievable tolerances depend on part size, geometry, and material. We routinely hold tight tolerances on precision-machined features across a range of materials. Contact our engineering team with your specific requirements for a detailed assessment.
What inspection equipment do you use?
Our quality lab includes a Nikon Altera CNC CMM with a measurement volume of 60 x 48 x 40 inches, a Faro Quantum portable CMM arm with a reach of 12 feet in a sphere, plus a full complement of surface plates, gauge blocks, and calibrated hand tools.
Do you provide first-article inspection reports?
Yes. We provide full AS9102 First Article Inspection Reports, dimensional inspection reports with GD and T callouts, and Certificates of Conformance as required by our customers.
Is IMT Precision ISO certified?
IMT Precision maintains a quality management system aligned with ISO 9001 standards and is actively pursuing formal certification.
Frequently Asked Questions
Company & Compliance
Is IMT Precision ISO certified?
Yes. IMT Precision is ISO 9001:2015 certified. Our certificate and scope statement are available for download by procurement teams conducting supplier qualification.
Where is IMT Precision located?
IMT Precision is located at 31902 Hayman Street, Hayward, CA 94544, in the San Francisco Bay Area, approximately 25 miles south of Oakland and 30 miles north of San Jose. Our Hayward facility houses all machining, welding, inspection, and assembly operations under one roof.
Do you serve customers outside California?
Yes. While we are based in Hayward, California, we ship large-envelope precision components to aerospace, semiconductor, and research customers across the United States and internationally. Our Bay Area location provides same-day truck access to Silicon Valley semiconductor OEMs, Southern California aerospace primes, and Pacific Northwest space companies.
Will you sign an NDA?
Yes. We routinely sign mutual non-disclosure agreements before reviewing proprietary drawings or CAD. Send your NDA with your RFQ to RFQ@imtp.com and we will execute it on receipt.
