What should be included in the first RFQ email?

Include robot type, joint location, continuous and peak torque, target speed, voltage/current window, duty cycle, mechanical envelope or STEP files, interface requirements, quantity plan, destination, and document needs.

What happens after we send a complete RFQ?

We review actuator fit, missing technical inputs, OEM customization scope, and available documents before responding with clarification questions or quote direction.

Can we discuss custom OEM requirements before PO?

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

Send QDD actuator specs, STEP files, or actuator references for engineering review.

RFQ visual references

Attach similar module references when sending requirements

If your team already has target packaging, output flange, hollow routing, or torque-density expectations, mention the closest visual reference in the inquiry so the first response can focus on model fit and customization limits.

Hollow rotary actuator module for cable-routing and compact joint review

Outer-rotor torque robot joint module for high-torque actuator review

RFQ Checklist Before You Send

Required Item	Example	Why It Helps
Robot and joint target	Quadruped knee, humanoid ankle, exoskeleton hip	Narrows the actuator architecture, load case, and integration assumptions.
Torque-speed-voltage target	Continuous torque, peak torque, speed, voltage, duty cycle	Prevents selection from peak torque or holding torque alone.
Mechanical interface	Shaft, flange, hollow routing, connector, STEP/drawing	Avoids sample mismatch and assembly rework.
Quantity and timeline	Prototype quantity, pilot run, annual forecast, target date	Improves lead-time and pricing accuracy.
Destination and documents	Country, Incoterm, datasheet/CAD/test-report needs	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.
QDD actuator target: joint location, torque-speed-voltage target, duty cycle, and backdrivability expectation.
Mechanical interface: shaft, flange, hollow routing, connector, drawing revision, or STEP file.
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 Resources for QDD architecture, backdrivability, torque-control, comparison, and thermal-sizing notes.

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.
