What Dolphin does
Dolphin, Inc. is a Phoenix, Arizona-based precision investment casting foundry that produces custom metal components using the lost-wax process with ceramic shell molds. Since its 1972 acquisition by Karsten Manufacturing Corp., the company has operated as a privately held, multi-generational family-run business serving aerospace (primary), sporting goods, railroad, and transportation manufacturers from a single 120,000-square-foot facility. Its core offering is built around a vertically integrated production stack that combines SolidWorks CAD design, ProJet MJP 3600W 3D-printed wax patterns, MPI APAS robotic wax assembly, automated shell-room dipping robotics, vacuum heat treating (NADCAP accredited with Merit Status), CNC machining and finishing, and in-house chemical and mechanical testing (including Hexagon CMM dimensional inspection and LEO CS744/GDS900 elemental analysis). The alloys catalog spans 300/400 series stainless steels, aluminum (A356/355/357), carbon and alloy steels, brass/bronze, precipitation-hardening stainless (15-5/17-4/17-7), and nickel-base alloys (Hastelloy C/B, Monel), with furnace capacity up to 7,500 lbs in steel and 750 lbs in aluminum.
Dolphin monetizes through custom, project-by-project quoting: customers submit part specifications, alloy requirements, testing needs, target prices, and annual volumes via an online quote form, and pricing is negotiated per part with multi-year contract cadence. GTM is direct B2B only, with no distribution partners, resellers, or marketplace channels, and the customer base is exclusively enterprise OEMs. The company holds AS9100D (2020), ISO 9001:2015, NADCAP Heat Treating (Merit, 2023), NADCAP Welding (2023), and PED (2014/68/EU) certifications, which collectively serve as the regulatory gatekeeper into aerospace and pressure-equipment programs.
Operationally, Dolphin markets itself on quality, on-time delivery, and single-source convenience (prototyping through finishing under one roof), supported by an average employee tenure of 10-15 years and a 47-year tenured employee. Revenue is not publicly disclosed; no funding rounds, M&A, or public-market events are reported, and operating scope is USA-only.

Dolphin competitors and assessment
Company assessmentBroad incumbents
- Precision Castparts Corp. Precision Castparts (a Berkshire Hathaway company) is the dominant US precision investment caster serving aerospace, power, and industrial markets. It directly competes with Dolphin on complex aerospace investment castings but operates at vastly larger scale, multiple facilities, and broader alloy capability, serving as the benchmark incumbent.
- Howmet Aerospace: Howmet Aerospace is a major global supplier of investment castings, forged components, and fastener systems for aerospace and industrial markets. It overlaps directly with Dolphin on aerospace structural and engine investment castings, but operates at enterprise scale with much broader product breadth.
- Arconic: Arconic is a large-scale aluminum and aerospace components manufacturer with substantial investment casting capability serving commercial aerospace and defense. It is comparable to Dolphin on aerospace component manufacturing and aluminum alloy casting, but operates at significantly larger scale and broader product portfolio.
Direct peers
- Doncasters Group: Doncasters is a UK-based precision investment casting specialist serving aerospace, industrial gas turbine, and defense end markets. It is highly comparable to Dolphin in core technology (lost-wax casting), target verticals (aerospace/industrial), and value proposition (complex certified castings), competing primarily outside Dolphin's US domestic market.
- Hitchiner Manufacturing: Hitchiner is a US-focused investment casting foundry serving aerospace, automotive, and industrial markets with countergravity and conventional lost-wax processes. It is one of the closest direct peers to Dolphin in terms of technology, customer verticals, and scale of operations.
- MetalTek International: MetalTek International is a US nonferrous and stainless investment casting foundry serving aerospace, defense, and industrial markets. It overlaps with Dolphin's alloy breadth (steel, nickel-base, bronze) and aerospace customer base, making it a strong comparable for US precision casting operations.
- Signicast (now part of CIREX): Signicast is a US precision investment casting foundry (now part of CIREX / Signicast Investment Castings) focused on rapid prototyping and high-mix production runs. It directly competes with Dolphin on quick-turn, smaller-batch aerospace and industrial castings.
Emerging players
- Wall Colmonoy: Wall Colmonoy is a US-based manufacturer of precision castings, coatings, and brazing alloys serving aerospace and industrial markets. It overlaps with Dolphin on aerospace-grade investment castings and alloy specialization, but is smaller and more specialized than Dolphin.
