What should be included in the first RFQ email?

Include target pull force/Gauss, max operating temperature, housing drawing (with tolerances), and estimated annual volume.

How quickly can we get an actionable quote?

Complete RFQs receive engineering feedback, DFM suggestions, and NRE/Unit pricing within 1-2 business days.

Do you offer prototype runs before mass production?

Yes. We frequently use Wire-EDM or CNC prototyping to validate the magnetic circuit before investing in expensive injection or sintering molds.

RFQ Checklist Before You Send

Required Item	Example	Why It Helps
Target Performance	15kg vertical pull force / 3000 Gauss at 2mm gap	Allows us to suggest a cheaper magnet grade if the magnetic circuit can be optimized.
Operating Temp	Max 150°C (Continuous)	Dictates the required NdFeB grade (e.g. SH/UH) and the type of structural epoxy.
Mechanical Drawing	STEP / PDF with critical tolerances	Ensures the steel housing can be machined accurately without breaking the brittle magnet.
Quantity Plan	100 pcs prototype, 50k/year mass production	Helps us structure your NRE (Tooling) rebates.
Destination	FOB Shenzhen / DDP Frankfurt	Magnets require special magnetic-shielded packaging for air freight.

What Happens After Inquiry

Engineering pre-check for DFM (Design for Manufacturability) and magnetic circuit viability.
Two-stage quotation: Prototype Tooling vs Mass Production NRE.
Sample scope alignment and Gauss/Pull-force testing methodology agreement.
First-Article Inspection (FAI) report delivery with physical samples.

Common Clarification Questions

Can I just ask for an N52 magnet quote instead of an assembly?

We specialize in complete magnetic assemblies. While we do supply bare magnets, our core engineering value is integrating the magnet into your mechanical housing to amplify flux.

Can you sign an NDA before we send our sensor/motor drawings?

Absolutely. Please email your company's standard mutual NDA to [email protected], and our management team will sign and return it within 24 hours.

How do we handle NRE (Tooling) costs for new designs?

We explicitly separate NRE costs for sintering molds, injection molds, and magnetizing fixtures. For mass-production projects, we offer NRE rebates once cumulative volume thresholds are met.

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 (e.g. BLDC motor rotor, holding latch, linear actuator).
Performance target: required pull force, Gauss reading at surface, or torque.
Environmental factors: Max operating temperature, exposure to chemicals/humidity.
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.

Typical First Response Package

Output	Purpose	Buyer Action
Model and architecture direction	Narrow viable options against torque-speed and interface 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.
