Core offering

Preci-Spark is a UK-based precision engineering contract manufacturer that produces complex fabricated components and assemblies for the aerospace, industrial gas turbine, and semiconductor markets. The company uses in-house special processes including EDM, laser machining, vacuum brazing, heat treatment, welding, CNC machining, and non-destructive testing to deliver products such as cooling inserts, honeycomb seals, 3D vanes, complex fabrications, general components, and semiconductor gas diffusers. Sales are conducted through direct B2B engagement with major OEMs and customers requiring precision components.

Product overview

Preci-Spark is a precision engineering manufacturer offering a portfolio of specialized components and complex assemblies to aerospace, industrial, and semiconductor markets. The product portfolio consists of six core product lines: Cooling Inserts (air impingement cooling units for gas turbines), Honeycomb Assemblies (seals for turbines and compressors), 3 Dimensional Vanes (tapered and twisted airfoils), Complex Fabrications (multi-part assemblies including combustion chambers and vane rings), General Components (tungsten busbars, titanium silencers, impingement plates, heat shields), and Semi-Conductor Products (gas diffusers/showerheads and UHV assemblies). These products are supported by an integrated suite of in-house manufacturing processes including laser machining, electro-discharge machining, conventional machining, vacuum brazing, heat treatment, welding, advanced metal forming, and inspection/non-destructive testing.

Products and services

• Cooling Inserts
• Honeycomb Assemblies Honeycomb seals for high-pressure turbines, low-pressure turbines and compressors, supplied to major OEMs. Includes both fabricated seal segments and seal rings. Production capacity exceeds 20,000 honeycomb seals per annum across multiple part numbers.
• 3 Dimensional Vanes Three dimensional vanes with tapered and twisted shapes in aluminium, steel and nickel alloys. Produced as fabricated hollow airfoils from sheet metal or machined from forgings/bar stock, with exacting contour definition. Sold to aerospace engine manufacturers.
• Complex Fabrications Multi-part fabricated solutions including combustion chamber components for engines and fabricated vane rings for turbochargers, produced using forming, welding, brazing and machining capabilities. Sold to engine manufacturers and industrial gas turbine OEMs.
• General Components Diverse range of sub-contract manufactured components including tungsten busbars, titanium silencers, impingement plates, heat shields, and gas purge manifolds. Processed using 125 EDM machines and 25 YAG lasers for a multi-industry customer base.
• Semi-Conductor Products Gas diffusers (showerheads) and ultra-high vacuum (UHV) assemblies, chambers and flanges for the semiconductor industry. Brazed tube showerhead diffusers with complex geometries achieving vacuum seals in excess of 10^-9 mbar, with assembly capability of over 50,000 brazed tubes across 3 chambers.

Direct peers

• Chromalloy: Independent provider of engineered repairs, castings, and manufactured parts for commercial and military gas turbine engines. Comparable as a niche engine component manufacturer working with cooling, sealing, and hot-section hardware for major engine programs.
• Bodycote plc: Global leader in heat treatment and thermal processing services for aerospace and industrial markets, including vacuum brazing and hot isostatic pressing. Closely comparable in process technology (vacuum brazing, heat treatment) and NADCAP-driven service model.
• Senior plc: UK-listed aerospace and defense fluid conveyance, structural, and precision engineered component supplier. Comparable as a UK-headquartered Tier 2 aerospace component manufacturer serving engine and airframe OEMs with complex fabricated assemblies.
• Barnes Aerospace: Division of Barnes Group supplying precision machined components and engine parts (including turbine and structural components) to commercial and military engine OEMs. Closely aligned to Preci-Spark's aerospace precision machining and turbine component focus.
• Doncasters Group: UK-based precision components manufacturer supplying aerospace, industrial gas turbine, and defense customers with cast and fabricated parts. Highly comparable to Preci-Spark in customer mix (major engine OEMs), manufacturing complexity, and UK mid-market supplier profile.
• Hayward Tyler: UK-based specialist in precision-engineered pumps, motors, and high-specification fabricated components for power generation and aerospace. Comparable as a UK mid-market precision engineering supplier serving demanding industrial and aerospace customers.
• Wallwork Group: UK-based heat treatment, vacuum brazing, and advanced surface coatings provider serving aerospace and industrial markets. Closely comparable in service mix (vacuum brazing, heat treatment) and UK mid-market scale, though more service-led than Preci-Spark's component focus.

Broad incumbents

• GKN Aerospace: Large UK-based Tier 1 aerospace supplier of engine and airframe structures, transparencies, and electrical wiring systems. Overlaps with Preci-Spark on engine structures and complex fabrications but operates at much greater scale with broader portfolio.
• Howmet Aerospace: Global Tier 1 supplier of engineered aerospace components including turbine airfoils, blades, seals, and structural castings. Comparable technology and end-market (engine hot section, seals) but at significantly larger scale and broader product portfolio.
• Meggitt (Parker Aerospace): UK-headquartered aerospace component supplier (now part of Parker) specializing in sensors, thermal management, and engine components. Overlapping customer base with major engine OEMs and shared UK aerospace supply chain heritage.
