Useful takeaways from this story.

Defense work now represents about 80% of its business, with customers including Boeing, General Dynamics, Northrop Grumman and Lockheed Martin.

The company operates at a Mansfield site it has occupied since 1969 and emphasizes certifications, engineering systems and strict safety practices on the shop floor.

# Forge does Trinity Forge & Machine makes built-to-print metal components using closed-die forging and precision machining. The company specializes in producing parts with complex shapes and tight tolerances to meet stringent customer specifications.

# How the business changed Trinity Forge started in 1955 in Hurst and moved to its current Mansfield location in 1969. For decades the company primarily supplied the oil and gas industry. As recently as 15 years ago, oil and gas accounted for about 70% of its work.

When much of the oil-and-gas forging business moved offshore, Trinity Forge shifted strategy. It invested in process controls, engineering capabilities and certifications that align with more demanding buyers. Today defense customers make up roughly 80% of the company's revenue.

# Customers and contracting Trinity Forge supplies parts to major defense primes and tier-one contractors. Named customers include Boeing, General Dynamics, Northrop Grumman and Lockheed Martin. Government contracts are awarded via competitive bidding, which requires consistent quality, traceability and adherence to contract specifications.

# Shop-floor practices and priorities

The company also prepares for government inspections by maintaining enterprise resource planning (ERP) systems and modern design software. These systems support traceability and process control that defense procurement requires.

# Location and local context Drive, a name that reflects early local plans for a regional airport that never materialized after DFW Airport was built. The vacant land created space for industrial growth, allowing Trinity Forge to expand where it did in 1969.

# Leadership and identity John Fairbanks, president and CEO, rejects a simplified "blacksmith" label for the company. He frames Trinity Forge as a modern, certified manufacturing contractor with engineering and machining depth that go beyond the historical image of forging.

# What this means for buyers and the local economy For defense contractors and government buyers, Trinity Forge offers onshore capacity for closed-die forging and tight-tolerance machining. For the Mansfield manufacturing base, the company represents a long-standing employer that retooled its capabilities to serve higher-specification markets.

# Bottom line
