What should be included in the first RFQ email?

Include array geometry, target field strength (Gauss/Tesla) and uniformity, max operating temperature, quantity plan, and destination.

How quickly can we get an actionable response?

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

Can we discuss custom OEM requirements before PO?

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

RFQ Checklist Before You Send

Required Item	Example	Why It Helps
Target magnetic assembly	Linear Halbach / Cylinder / Custom Rotor	Quickly narrows viable models and quote range.
Field strength & gap	1.2 Tesla peak at 5mm gap	Defines magnet grade, array pitch, and simulation target.
Mechanical interface	Shaft, flange, connector drawing revision	Avoids sample mismatch and assembly rework.
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.

What Happens After Inquiry

Engineering pre-check for model fit and data completeness.
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

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.

How should we handle engineering changes after sample approval?

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

Can we align on compliance files before mass production?

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

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 application scenario.
Magnetic target: field strength, uniformity, and operating temperature (for grade selection).
Mechanical interface: shaft, flange, connector, drawing revision.
Commercial scope: prototype quantity, annual forecast, destination, and target ship date.

What You Should Review Before Sending RFQ

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.
FEA Simulation for understanding field modeling before physical prototyping.
Quality Inspection for learning about our 3D Gauss mapping and testing capabilities.
Export Compliance Support for aligning material trace files, shipment documents, and magnetic goods packing before PO.

Typical First Response Package

Output	Purpose	Buyer Action
Model and architecture direction	Narrow viable options against field-strength requirements and geometric 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.
