What Anderson Stewart Castings does

Anderson Stewart Castings is a UK-based precision investment casting manufacturer, founded circa 1974 and operating for over 50 years from its headquarters at Lochshore East Industrial Estate in Beith, North Ayrshire, Scotland. The company specializes in the Lost Wax investment casting process to produce complex, high-integrity components in a wide range of ferrous, non-ferrous, and speciality alloys, many of which are safety-critical for arduous applications. It complements its core casting capability with on-site tooling and fixture design using Solidworks software, rapid prototype castings enabled by Stratasys 3D printing, heat treatment, testing, surface finishing, and global sourcing of castings, forgings, and materials through trusted supply partners. Sister company Precision Tooling Services, located at Aerospace Park in Prestwick, extends the offering to fully engineered finished components through CNC and conventional machining, providing customers with a single-source cast-to-finished-part solution.

The business serves six primary verticals — automotive, railway, nuclear, oil & gas, marine, and general engineering — through a direct B2B sales motion targeting enterprise customers globally. Anderson Stewart Castings is part of the Precision Tooling and Castings Group, which in 2024 transitioned to an Employee Ownership Trust, placing ownership with the workforce rather than external shareholders. The company holds ISO 9001:2015 accreditation (held continuously for over 20 years), Cyber Essentials certification, and adheres to nuclear-sector quality procedures including APQP, PPAP, PFMEA, FMEA, and MSA. Recent strategic initiatives include a Digital Foundry Transformation under the 5GIR Fund deploying smart wireless sensors for real-time slurry monitoring and automated dosing, simulation-driven process optimization, and a formal commitment to net-zero greenhouse gas emissions by 2040.

Revenue is generated primarily through hardware sales of precision castings, supplemented by professional services revenue from tooling design, machining, heat treatment, testing, and surface finishing. Pricing is quote-based and not publicly disclosed, reflecting the custom, project-driven nature of the work. The company markets itself through its own website, an active LinkedIn and Facebook presence, and displays industry accreditations and trade-body memberships (ICME, Scottish Engineering 2025, Industrial Innovation Awards 2025) as trust signals. No named end-customer logos, revenue figures, or headcount are publicly disclosed, and the company operates as a private entity with no external funding rounds or acquisitions on record.
