What should be included in the first RFQ email?

Include furnace type, CAD or 2D drawing, material grade (e.g. Ash < 5ppm), max operating temperature, quantity plan, and delivery destination.

How quickly can we get an actionable response?

Most complete RFQs receive first-round engineering feedback and quote direction within one business day.

Yes. We encourage pre-PO engineering clarification to reduce prototype and mass-production risk.

Use the form for first-round specs. Email remains available for drawings, CAD files, and NDA-controlled attachments.

Required Item	Example	Why It Helps
Target graphite component	Crucible size / purity grade / TaC coating	Quickly narrows viable materials and quote range.
Max operating temperature	e.g., 2400°C for SiC PVT	Prevents premature material degradation in extreme environments.
CAD & Dimensional tolerances	STEP/IGES file, 2D drawing (PDF), threading, and surface finish	Avoids assembly interference inside the hot zone.
Quantity plan	Prototype qty + annual forecast	Improves lead-time and pricing accuracy.
Destination and terms	Country, Incoterm, requested ship date	Aligns packaging, documents, and shipping plan early.

Graphite grade, density, and material-batch reference.
Ash, impurity, coating, or inspection report scope agreed before sample approval.
Critical-dimension inspection, cleaning, sealing, packaging, and photo records when required by RFQ.

Certification, origin, and compliance files are quoted only when available and requested.
Furnace fit, coating life, and process outcome depend on buyer-side validation.
Final lead time depends on drawing complexity, purification, coating, quantity, destination, and documents.

Yes. Send your current assumptions first, then mark pending items clearly so we can return a provisional quote scope.

Use a revision-controlled change request with effective lot and impact scope agreed by both teams.

Yes. Please list required document types in the RFQ stage so they are included in validation and delivery planning.

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 application scenario.
Graphite component target: size candidate, purity grade, thermal environment.
Dimensional interface: drawing revision, tolerances, surface finish.
Commercial scope: prototype quantity, annual forecast, destination, and target ship date.

Products for architecture-level selection and model-family fit.
Solutions / Applications for scenario-specific constraints and validation priorities.
OEM Capabilities for design collaboration, quality controls, and delivery process.
Engineering Blog for practical checklists you can copy into buyer workflows.

Output	Purpose	Buyer Action
Material and architecture direction	Narrow viable options against thermal and purity assumptions.	Confirm baseline model path before cost-detail discussion.
RFQ clarification list	Close data gaps that affect pricing and lead-time accuracy.	Return missing values and drawing references in one reply.
Validation recommendation	Define sample test scope and acceptance evidence for technical sign-off.	Align internal engineering and procurement gates before PO.
