| DED Layer Thickness | 0.2 - 0.5 mm |
| Final Surface Finish | Ra 0.1 - 0.2 μm (sealing surfaces) |
| Dimensional Tolerance | ±0.005 mm (critical bores) |
| Flatness | < 0.2 μm (sealing surfaces) |
| Cylindricity | < 0.01 mm (API 6A compliant) |
Powder-bed fusion (SLM/DMLS) uses only 10–20% excess material versus CNC machining from solid, which may remove 80% of raw material.
Example: AlSi10Mg automotive parts achieve 70% lower material costs.
The process combines Directed Energy Deposition (DED) repair, 5-axis precision CNC grinding finishing, Binder Jetting (Metal), and Ceramic & Composite 3D Printing.
It delivers 300% longer service life compared to new components, 60% cost savings compared to full replacement, reduces equipment downtime by 75%, and maintains original component dimensions and tolerances.
We achieve a surface finish of Ra 0.1-0.2μm and flatness <0.2μm on sealing surfaces, dimensional tolerances of ±0.005mm on critical bores, and cylindricity <0.01mm (API 6A compliant).
Quality control includes 100% CMM dimensional verification, Ra surface measurement (<0.2μm on sealing faces), Rockwell C hardness testing (45 HRC), non-destructive examination (PT/UT), and ASTM F75 certification.
Primary applications include gate valve seats and wedges, ball valve seats, choke valve components, Christmas tree valves, and pipeline isolation valves in severe oil and gas operating environments.
Powder-bed fusion (SLM/DMLS) uses only 10–20% excess material compared to solid CNC machining, which may remove up to 80% of raw material, resulting in up to 70% lower material costs (as seen in AlSi10Mg parts).
