What is UHV Sealing Rings & Chamber Compression Hardware?
🔄 UHV Sealing Rings & Chamber Compression Hardware represents a complete system of precision titanium components engineered for Semiconductor applications. KF/ISO centering rings, segmented circular clamping rings, Conflat knife-edge rings, O-ring groove retainers, vented vacuum screws, high-load flange washers, gate valve seal retainers, oval slit-valve bezels, quartz window retaining bezels, split-ring quick-release segments The system integrates 6 distinct component types manufactured through 3 specialized processes.
Key manufacturing processes for this system include Cleanroom CNC Class 100 for chamber hardware geometry, Electropolish Ra <0.25um for net-shape tolerance, UHP DI water cascade rinse for net-shape tolerance, Particle count MIL-STD-1246 for net-shape tolerance, Electropolish Ra <0.25um with SPC sampling, each selected and qualified to meet component-specific requirements.
Engineering & Design Principles
Material: Grade 5 (Ti-6Al-4V) for Conflat knife-edge rings, clamping rings, and vented screws requiring high hardness and strength. Grade 2 for centering rings and retainers requiring low cost and corrosion res
Form: Bar/ring forgings for circular sealing components. Plate for slit-valve bezels and window retainers. All sealing surfaces require single-point diamond turning for mirror finish.
Standards & Material Specifications
Standards: ASTM B348 Grade 5 (rings/screws) / Grade 2 (retainers), diamond-turned sealing surfaces, 100% He leak tested

1 Part Feature Analysis
Small precision conical/cylindrical parts with internal taper for valve stem locking, external spring seat shoulder, lightweighting grooves
- ⚠️ Inertia at high RPM (>10,000 RPM)
- ⚠️ Impact fatigue from valve closure
- ⚠️ High temperature under hood (150-250C)
- ⚠️ Wear at stem keeper interface
- ⚠️ Weight for valvetrain dynamics
2 Material Selection Rationale
Ti-15V-3Cr-3Sn-3Al — Beta alloy, high strength, excellent cold formability
Ti-153 (Ti-15V-3Cr-3Sn-3Al) is a beta alloy offering ultra-high strength (>1200MPa) with excellent fatigue life, providing 40% weight reduction vs steel retainers for high-RPM engines.
3 Form Selection Rationale
Round Bar / Rod — for turning, fasteners
Small diameter bar stock for CNC turning of retainers and keepers. Multi-spindle automatic lathes enable high-volume production.
4 Manufacturing Process & Services

Process Pitfalls:
- ⚠️ Valve stem collet groove concentricity must be <0.025mm TIR to prevent uneven loading
- ⚠️ Shot peening intensity must be carefully controlled to avoid peening-induced cracking
