Can I send a rough requirement before final drawings are ready?
Yes. Send your current assumptions first, then mark pending items clearly so we can return a provisional quote scope.

RFQ Checklist Before You Send
| Required Item | Example | Why It Helps |
|---|---|---|
| Process Application | SiC PVT, MOCVD, epitaxy, vacuum furnace, aluminum degassing, dry vacuum pump | Determines whether graphite, SiC coated graphite, C/C composite, or carbon felt is the correct path. |
| Product Type | Graphite, SiC coated graphite, C/C composite, carbon felt | Routes the RFQ to machining, CVD coating, composite, or insulation review. |
| Mechanical Interface | 2D/3D CAD drawing, PDF, marked-up photo, or sample | Required for precision CNC machining and tolerances. |
| Material Specs | Grade, density, ash target, trace elements, coating thickness, or lifetime target | Prevents contamination, premature coating failure, and wrong-base-material quotes. |
| Dimensions and Finish | OD/ID/height, pocket depth, tolerance, Ra, thread standard | Clarifies CNC complexity, inspection method, and acceptance criteria. |
| Operating Conditions | Temperature, atmosphere, corrosive gases, load, replacement cycle | Validates thermal shock, oxidation, coating, and C/C load-bearing risks. |
| Quantity & Demand | Prototype 5pcs, Annual 500pcs | Improves lead-time and bulk pricing accuracy. |
| Destination and terms | Country, requested ship date, DDP/FOB | Aligns export packaging, customs, and logistics early. |
What Happens After Inquiry
- Engineering pre-check for drawing completeness and DFM.
- Quote direction with lead-time assumptions and risk notes.
- Sample scope alignment and validation acceptance criteria.
- Production and delivery planning for approved programs.
Common Clarification Questions
Will you sign an NDA before reviewing our designs?
Absolutely. We routinely sign NDAs to protect your semiconductor hot zone or wafer carrier designs.
Can we align on trace metal analysis (COA) before mass production?
Yes. Please specify the critical elements (e.g., Fe, V, Ti) in the RFQ stage so we can include ICP-MS testing in the delivery plan.
Suggested First RFQ Email Format
If your team needs a fast start, use this structure in the first email. It improves quote precision and reduces clarification cycles.
- Project background and target equipment (e.g., Aixtron MOCVD).
- Product and material target: graphite grade, density, ash target, SiC coating thickness, C/C architecture, or carbon felt requirements.
- Attachments: 2D drawing with tolerances, 3D STEP file, marked-up photo, or current sample reference.
- Operating conditions: temperature, atmosphere, load, lifetime target, and current replacement cycle.
- Commercial scope: prototype quantity, annual forecast, destination, and target ship date.
What You Should Review Before Sending RFQ
- Products for material-level selection and capability fit.
- Solutions / Applications for process-specific constraints and validation priorities.
- OEM Capabilities for machining tolerances, purification controls, and delivery process.
