What FST does

FST (Flame Spray Technologies BV) is a Dutch industrial equipment manufacturer founded in 1997 and headquartered in Duiven, the Netherlands, operating as part of the STS Group. The company designs, manufactures, and installs turn-key thermal spray coating systems as well as modular stand-alone equipment spanning all six major thermal spray processes — High-Velocity Oxygen Fuel (HVOF), Atmospheric Plasma Spray (APS), Cold Gas Spray, Arc Wire Spray, Flame Powder Spray, and Flame Wire Spray. Its product portfolio includes the HV-50, MP-50 multi-process platform, and AP-50 plasma systems; a broad spray gun line (eGun™, JP-5000, DJ2600/2700, JetKote 3000, 9MB/3MB/F4 plasma, AWS-400 arc); the proprietary Horizon™ control software; auxiliary equipment (Tecnar Accuraspray 4.0 diagnostics, powder feeders, chillers, dust extraction, acoustical booths); and a full range of consumables (powders, wires, spare parts). FST holds ISO 9001:2020 and ISO 14001:2020 certifications, and holds registered trademarks on eGun™, cGun™, and Horizon™.\n\nFST's customers are predominantly large industrial enterprises in Industrial Gas Turbine, Aerospace, Oil & Gas, Paper & Printing, and general engineering — with named references including Rolls-Royce, Siemens, TEI, Sartori, Cromostamp, and (notably) Samsung, which awarded a KRW 25 billion contract for EUV pellicle handling equipment at the Taylor, Texas fab, marking FST's entry into semiconductor capital equipment. Revenue is generated through quote-based direct enterprise sales of turn-key systems and modular equipment, recurring consumables and spare-parts, and a growing services layer covering preventive maintenance, calibration, AR-based remote assistance (FST | Remote Assistance™), metallographic laboratory testing, and coating engineering consulting in partnership with Surface Engineering & Innovation Ltd. The company maintains its own offices across Europe, the Americas, Asia, the Middle East, and Africa, with 101-250 employees. Cold spray capability is delivered through a partnership with Impact Innovations GmbH.
