RFQ Checklist
- Part drawing or failed part sample dimensions
- Furnace type, temperature, atmosphere, and loading condition
- Replacement interval and failure mode if known
- Quantity, spare inventory target, and destination
Machined graphite trays, boats, plates, supports, heating parts, and insulation-related fixtures for vacuum and high-temperature furnaces.
Complete RFQs are easier to review within 1-2 business days when drawings, graphite grade, quantity, and destination are included.

| Option | Best Fit | Watchouts |
|---|---|---|
| Molded or extruded graphite fixture | Larger trays, plates, spacers, support blocks, and furnace parts where size and thermal function dominate. | Confirm grain direction, support points, load, temperature gradient, and edge protection. |
| Isostatic graphite fixture | Precision supports, small high-stress details, holders, or fixtures where uniform properties and machining detail matter. | Review thin sections, threaded features, repeated thermal shock, and inspection datum before finalizing design. |
| Treated graphite or hot-zone component | Oxidation-prone exposure, contamination-sensitive furnaces, or parts where surface behavior affects process stability. | Specify atmosphere, treatment expectation, packing, and any furnace OEM acceptance criteria. |
Review sample photos, failed areas, drawing notes, support points, load path, and replacement interval.
Match grade to furnace atmosphere, temperature, thermal shock, load, contamination risk, and spare inventory plan.
Machine trays, slots, holes, spacers, and supports with graphite dust control and handling plans for large brittle parts.
Check drawing-critical dimensions, support faces, flatness where specified, labels, and reinforced packing for long parts or open slots.
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Thermal cycle fit | Defined by furnace process | Furnace fixtures fail when grade, geometry, and loading are not matched to thermal cycling. |
| Spare-part repeatability | Drawing-controlled replacement batches | Maintenance teams need predictable replacement parts to reduce downtime. |
| Load path and support condition | Tray, boat, spacer, holder, support, heater, or hot-zone part | Graphite fixture life depends on where the part is supported, heated, loaded, and cooled. |


If a sample or detailed photos are available, we can help build an RFQ drawing package. Critical dimensions still need buyer confirmation.
Yes. Repeat programs are a strong fit because graphite furnace fixtures are consumables in many high-temperature processes.
Send furnace type, temperature, atmosphere, loading pattern, support points, current failure photos, and replacement interval. That context helps review grade and geometry instead of only copying dimensions.
