What should be included in the first RFQ email?

Include program stage, joint position, CAD and drawing revision status, peak and continuous torque or force, target speed, duty cycle, thermal boundary, mechanical envelope, voltage, protocol, encoder and brake expectations, prototype quantity, pilot forecast, destination, and timeline.

How quickly can we get an actionable response?

Complete RFQs are prioritized for technical receipt within 24 hours, DFM questions within 3 business days, and quote direction within 7 business days when the minimum engineering dataset is complete; actual timing depends on scope, attachment quality, and engineering availability.

Can we discuss custom OEM requirements before PO?

Yes. Use the form or WhatsApp application engineer channel to align the engineering baseline, NRE assumptions, validation evidence, and prototype-to-pilot plan before purchase order release.

Engineering RFQ

Contact / RFQ

Share the minimum engineering dataset for a custom humanoid actuator review: program stage, joint CAD status, torque-speed target, thermal boundary, electrical interface, prototype quantity, pilot forecast, destination, and timeline.

24-Hour Intake Target

Complete RFQs are targeted for technical receipt within one business day.

3-Day DFM Target

Initial manufacturability and thermal questions after baseline data is complete.

7-Day Quote Direction

Scope, NRE, lead-time risk, and evidence direction after engineering review.

Buyer Qualification

Built for Complete Engineering RFQs

This contact path is designed to reduce the clarification loops that slow custom actuator programs. The strongest first inquiry includes joint CAD status, torque-speed targets, thermal boundary, interface constraints, prototype quantity, pilot forecast, and validation evidence.

Use This Page When

Your team has a serious humanoid robot program, a joint map or CAD direction, funding or purchasing path, and a need to turn nonstandard actuator requirements into manufacturable samples or pilot hardware.

Send Email Instead When

You need to attach STEP, PDF drawings, Gerber files, BOM exports, test data, or CC multiple engineering and procurement stakeholders in the first thread.

Not a Fit Yet

Broad hobby sample requests, generic servo shopping, and price-only inquiries without torque-speed, package, quantity, or timeline data usually cannot reach an actionable quote.

Minimum Dataset

8-Point Engineering Baseline Before Quote

A provisional quote can start with TBD values, but missing baseline data should be called out explicitly. These eight inputs determine whether the next step is DFM, FEA/thermal review, sample scope, or a formal quotation path.

Baseline	Input to Send	Why It Matters
Program maturity	Funding or purchasing path, prototype / EVT / DVT / pilot stage, NRE expectation, and decision owner.	Filters real ODM programs from casual browsing and sets the commercial review depth.
Joint map and axis	Hip, knee, ankle, shoulder, elbow, wrist, hand, neck, waist, or special-axis responsibility.	Different joints have different load, brake, reducer, bearing, and thermal priorities.
CAD and drawing status	3D CAD availability, 2D drawing revision, flange or shaft version, cable path, and frozen vs open interfaces.	Prevents samples from being quoted against hidden mechanical assumptions.
Torque-speed target	Peak torque or force, continuous rating, target speed, overload event, and stall duration if relevant.	Keeps sizing from being driven by peak marketing values instead of thermal reality.
Duty cycle and thermal boundary	Walk / lift / grasp cycle, ambient temperature, sealed housing state, cooling path, and continuous derating expectation.	Determines whether the actuator can survive the real humanoid workload.
Mechanical and reducer limits	Envelope, hollow-bore need, bearing support, reduction ratio, backlash limit, and test condition where defined.	Connects packaging, stiffness, impact behavior, and inspection scope before machining.
Electrical and control boundary	Voltage, protocol, encoder, brake, driver location, harness route, and approved or restricted component choices.	Avoids prototypes that fit mechanically but fail integration, routing, or control assumptions.
Pilot and delivery plan	Prototype quantity, pilot forecast, annual forecast, validation evidence, destination country, Incoterm, and timeline.	Aligns sample evidence, production readiness, packaging, and shipment planning early.

RFQ Checklist Before You Send

Required Item	Example	Why It Helps
Joint and envelope	Hip, knee, ankle, shoulder, elbow, wrist, hand, or custom linkage; include CAD and drawing revision	Confirms whether a custom actuator package is physically manufacturable.
Load and motion target	Peak torque, continuous torque, speed, duty cycle, overload event, or linear force and stroke	Prevents sizing from peak torque alone and exposes thermal risk early.
Interface and electronics	Flange, hollow shaft, cable exit, voltage, protocol, encoder, brake, and driver location	Avoids actuator samples that fit mechanically but fail controls, routing, or assembly.
Program stage	Prototype, EVT, DVT, pilot quantity, annual forecast, and target schedule	Aligns tooling, sample evidence, inspection scope, and lead-time planning.
Destination and terms	Country, Incoterm, requested ship date	Aligns packaging, documents, and shipping plan early.

What Happens After Inquiry

Step	Timing	Output
Technical receipt	Target: within 24 hours	Confirm the RFQ was received and flag whether the minimum engineering dataset is complete enough for review.
DFM clarification	Target: within 3 business days	Return questions on torque-speed, package, thermal path, interface, electronics, inspection, and validation gaps.
Quote direction	Target: within 7 business days after complete data	Provide quotation direction, NRE and sample assumptions, lead-time risks, and the evidence needed before PO.
Sample-to-pilot handoff	After scope alignment	Align drawing freeze, FAI/CMM scope, dynamic tests, pilot acceptance, traceability, packaging, and delivery plan.

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.
Actuator target: joint axis, peak and continuous torque or force, speed, duty cycle, and electrical window.
Mechanical interface: shaft, flange, connector, drawing revision.
Commercial scope: prototype quantity, annual forecast, destination, and target ship date.

For a fuller buyer-side package, review the sample humanoid actuator RFQ package, then use the evidence library to decide which report types should be requested before sample approval or pilot release.
