Why Investment Casting for Vacuum Fittings?
Unlike die-casting, investment casting (lost-wax) delivers:
- Near-net-shape precision for complex flange geometries
- Superior surface finish reducing post-machining and outgassing
- No parting lines ensuring consistent seal integrity
- Material flexibility with 304/316L stainless steel options
Post-cast CNC machining achieves the tight tolerances and smooth surfaces essential for reliable high-vacuum sealing.
