Wah Son Engineering

What Wah Son Engineering does

Wah Son Engineering Pte Ltd is a Singapore-headquartered precision manufacturer (51-100 employees, single site at Seletar Aerospace Heights) specializing in high-complexity tooling for the aerospace industry, serving major engine and nacelle OEMs and MRO providers. Its product portfolio spans assembly and disassembly tools for engines and modules, component repair tooling, engine transportation stands and ground support equipment (GSE), engine test adaptors, fabrication, machining, and inspection fixtures, lifting devices, line maintenance tooling, and passenger-to-freight conversion tooling. Core technical capability rests on large-format precision machining — including an SHW UniForce6 5-axis-simultaneous centre with a 10m x 1.6m x 4m work envelope, multiple Toshiba 5-face double-column and vertical turn-mill centres, a DMG Mori NHX8000, conventional milling/lathe/grinding, MIG/TIG/Arc welding with certified welders, and metrology via a Leica AT960 Absolute Laser Tracker with 3D scanner, Mitutoyo CMM, and Hexagon GLOBAL S SCAN+ CMM. The business operates a build-to-print, quote-based model with customers paying per project, supplemented by recurring revenue from repair, calibration, and periodic proof-loading services on the installed tooling fleet, plus design services for structural interface elements and shot-peening fixtures. The go-to-market is direct enterprise field sales to a small set of Tier-1 aerospace accounts — GE Aviation (DSQR), RHINESTAHL, Rolls-Royce plc (SABRe-approved), SAESL, Pratt & Whitney, and Collins Aerospace (Licensed Provider of Program Aircraft MRO Tooling) — with revenue concentration in aerospace OEMs and MRO facilities, and a secondary segment in non-aerospace precision engineering machining. The company also runs an Engineering Incubator/Accelerator initiative offering Design-to-Fabrication services, shared CAD/CAM and metalworking access, and learning solutions targeting institutes of higher learning and engineering startups.
