On the shop floor
We bridge the gap betweenengineering intent andmanufacturable reality.
Bret Hartman · Founder / CEO
Engineered first
Geometry, gating, and machining strategy reviewed before any tooling spend. Print arrives, engineering responds — not a quote bot.
Vertically integrated
Design review, pattern, pour, machine, inspect — one shop, one schedule. No handoffs, no waiting on a subcontractor queue.
Spec-locked
±0.0005″ machined tolerance, with 2026 clean-room CMM inspection supporting .0001″ measurement on machined surfaces. The part performs because the process produced it that way.
Capabilities
Concept to finished component.
Six disciplines, one shop. Vertically integrated from V-process casting through Mazak / Enshu machining and CMM inspection — no handoffs, no schedule slippage waiting on someone else’s queue.

Company history
Built in Gilmer from a Hartman foundry lineage.
Applied Metallurgical was founded in 2021 in Gilmer, Texas. Its operating model was shaped several years earlier when Bret Hartman began refining V-process technology around a vertically integrated shop: cast, machine, inspect, and deliver completed components from one facility.
That model reduces outside processing, tightens scheduling control, and positions the company for stronger margins than the traditional foundry model. The next planned expansion, Plant 2, is designed for up to 8 tons of castings per day with additional Mazak 8800 machining centers and 36-pallet automation systems.
Late 2019
V-process development begins
Founder and CEO Bret Hartman began engineering and refining V-process technology to reduce production cost, increase efficiency, and support fully completed component manufacturing.
2021
Applied Metallurgical opens in Gilmer
Production operations were built from the ground up in Gilmer, Texas, with equipment and machines moved from Commercial Machine / Commercial Castings into the new plant.
2021–present
Casting and machining under one roof
The shop combines foundry and machining capabilities into a one-stop manufacturing operation for customers that need completed components, not disconnected vendor handoffs.
Lineage
From Commercial Castings to Applied Metallurgical.
1940–1980
Commercial Castings
Developed by Mel Hartman and associates in Los Angeles, California, focused on mid-size to large castings.
1988–2020
Commercial Castings / Commercial Machine
Operations moved to Fontana, California, with separate facilities for foundry production, mold and core construction, painting and staging, machining, and customer pattern storage.
2021–present
Applied Metallurgical
Equipment and machines from Commercial Machine / Commercial Castings were transported to Gilmer, Texas, where AMC refined production practices around V-process casting and in-house machining.
Milestones
Capacity, automation, and inspection.
V-process
- 2021: first successful V-process castings produced.
- 2022–2025: V-process capacity expanded to three part numbers while production efficiency grew by 200%.
- 2026: V-process efficiency reached max capacity and plant automation began construction alongside daily production.
Machining + inspection
- 2021: Mazak 8800 installation.
- 2022: Enshu 4-axis machine dedicated to medical parts begins operation.
- 2026: inspection department begins clean-room construction for temperature and humidity controlled CMM inspection to .0001" on machined surfaces.
