What SEKO does

SEKO Group is a Czech Republic-headquartered precision manufacturing group founded in 1991 by Vlastimil Sedláček, producing flight-critical and energy-grade components for aerospace engines, steam and water turbines, and industrial cutting tools. Core production technology is centered on EDM, multi-axis CNC machining, and — as of December 2023 — fully robotic MCM (multi-control multi-axis) machine tools, operated across six facilities located in the Czech Republic (including the Louny headquarters), Brazil, and India via joint ventures (Manuita Do Brasil and SEKO SHIVAM Engitech). The customer base is concentrated among tier-1 aerospace OEMs — specifically Honeywell, Pratt & Whitney, Safran, and GE Aerospace — together with major turbine and energy-sector OEMs; the company holds NADCAP, AS9100D, ISO 9001, and ISO 19443 certifications required to serve these accounts.

The business model is B2B custom contract manufacturing: SEKO bids on engineered, low-volume, high-mix precision parts under long-cycle supply agreements tied to OEM qualification programs, with revenue tied to the build-rate of the underlying aircraft engine and turbine platforms. The firm is privately held by the Sedláček family and operates with approximately 600 employees, the majority based at the Louny facility. Pricing is quote-based per part, with revenue mechanics driven by qualified-supplier status, multi-year framework agreements, and recurring aftermarket demand for spare and overhaul components in the energy segment.

Direct peers

• Senior plc: UK-listed precision engineered components manufacturer serving aerospace (fluid conveyance, structural, propulsion) and energy (land-based turbines, oil & gas). Directly comparable to SEKO as a precision machined components supplier to commercial aerospace engine OEMs with global manufacturing footprint.
• Walter Tools (Walter AG): German-based precision cutting tool manufacturer (part of the Sandvik group) producing milling, turning, drilling, and threading tools for industrial manufacturing. Comparable to SEKO Tool's cutting tools, molds, and fixtures business line.
• Doncasters Group: Privately-held manufacturer of precision castings and machined components for aerospace engines and industrial gas turbines. Closely comparable to SEKO in serving both aircraft engine OEMs and power-generation turbine customers with high-precision components.
• Magellan Aerospace: Canadian aerospace supplier producing precision-machined components, assemblies, and engine programs for commercial and defense aerospace markets. Comparable in precision machining for engine OEMs (Pratt & Whitney, GE) and global manufacturing footprint.
