What should be included in the first RFQ email?

Include reducer type, reduction ratio, rated and peak torque, backlash target, duty cycle, interface drawing revision, quantity plan, and destination.

How quickly can we get an actionable response?

Complete RFQs can move to first-round engineering feedback faster. When data is missing, the first response is usually a clarification list covering specs, drawings, quantity, and delivery assumptions.

Can we discuss custom OEM requirements before PO?

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

Contact

Contact / RFQ

Share your application, reducer targets, interface constraints, and quantity plan for sales engineering review.

Inquiry Routing

Choose the channel by engineering risk, not by convenience.

Quick chat is useful for triage. Drawings, NDA terms, CAD / STEP release constraints, and inspection-record requests should remain traceable by email or structured RFQ.

CAD / STEP availability

Use this route when your engineer needs a checked file-release path, 2D envelope, sample data pack, NDA handling, or drawing revision review.

Structured RFQ

Best for ratio, torque, backlash, interface, quantity, delivery country, and sample acceptance scope in one record.

RFQ Checklist Before You Send

Required Item	Example	Why It Helps
Target reducer family	Micro / compact / hollow shaft / low backlash	Quickly narrows viable reducer architectures and quote range.
Torque and ratio	51:1, 5 Nm rated, 20 Nm peak	Defines load margin, output speed, and expected reducer size.
Mechanical interface	Hollow shaft, output flange, input bore, bolt circle	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.
Reducer target: ratio, rated torque, peak torque, backlash, and duty cycle.
Mechanical interface: hollow shaft, output flange, input bore, bolt circle, and 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.
Include preferred reduction ratio, backlash class, lubrication preference, and operating temperature when these values are known.
Share STEP, PDF, or envelope drawings by email when your inquiry includes a custom shaft, flange, or housing requirement.

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.
