Select the process by geometry, material, damage, quantity and required delivery.
| Route | Principle | Precision / finish reference | Materials | Application / delivery |
|---|---|---|---|---|
| SLM / LPBF | Laser melts a powder bed layer by layer | ±0.02 mm; Ra ≤1.6 μm after polishing | TC4; Inconel 625 / 718; stainless steel | Complex channels, six-stage trim, conformal cooling; 1–2 weeks |
| DED | Laser with powder / wire deposited onto a substrate | ±0.1 mm | Stellite; Inconel; martensitic stainless steel | Seats, sealing faces and material upgrades; workshop / site repair assessed by access |
| WAAM | Arc heat melts wire for layerwise deposition | ±0.3 mm | Steel; titanium; aluminium wire | Large bodies, flanges and repair sections; more machining allowance; pressure-part qualification is separate |
| Hybrid / multi-material | SLM / DED with dissimilar or graded materials | Depends on the primary process | Titanium–steel; nickel–steel transitions | Corrosion-resistant surface and wear-resistant core; application-specific development |
| Conventional routes | Casting / forging, welding, CNC / EDM machining | Ra 6.3–12.5 μm | Cast iron, carbon steel and alloys | Standard bodies and simple series parts; 5–12 weeks; tooling and access constraints |
A combined manufacturing and repair system
SLM creates complex internal geometry; DED restores damaged areas; hybrid routes tailor material zones; WAAM addresses large-format applications. Reverse engineering, inspection and assembly connect the selected route into one delivery process.
Reference values from the technical proposal. Results depend on the material, component, processing condition and operating duty; the drawing and agreed acceptance plan govern each order.
For non-pressure-retaining wear parts: valve trim, seats and sealing surfaces. Pressure-retaining components require project-specific qualification before acceptance.
DED Technology
Laser cladding rebuilds locally damaged valve seats, sealing surfaces, shafts and stems while retaining a serviceable base.
SLM Technology
Selective Laser Melting (SLM / LPBF) creates complex internal channels for non-pressure-retaining fluid-control parts.
Flow Channel Design
Design the flow path around pressure differential, cavitation, solids and cleanability.
Material Library
Four material systems for erosion, corrosion, elevated temperature and lightweight fluid-control parts.
