RFQ preparation guide
Prepare a clearer injection moulding quote request.
Use this guide before sending drawings or requesting a quote. It explains the files, quantities, materials, tolerances, confidentiality notes, and project details that help create a more useful manual review.
Quick answer
What makes an RFQ easier to review?
A stronger injection moulding RFQ makes the project visible enough for useful manual review. It does not need to be perfect, but it should explain what is known and what remains uncertain.
RFQ checklist
Seven details that improve the first review.
These details help determine whether the project is ready for tooling discussion, needs DFM support, or should start with a lighter drawing review.
Drawings and CAD files
STEP, STP, IGES, PDF, DWG, DXF, sketches, screenshots, or part photos can all help establish the starting point.
Estimated quantity
Include prototype needs, first-order quantity, expected annual volume, or the volume range being considered.
Material direction
Share resin preference, performance requirements, environmental exposure, flame-rating needs, or say if the material is unknown.
Tolerances and finish
Identify critical dimensions, cosmetic requirements, surface finish expectations, fit concerns, and inspection priorities.
Application context
Explain how the part is used, what it connects to, where it operates, and which functions matter most.
Timing and logistics
Share launch timing, sample expectations, delivery location, packaging needs, and any project deadlines.
Confidentiality needs
Tell us if NDA-friendly handling is needed before sensitive files or proprietary information are shared.
Which path should you use?
Choose the intake path that matches your project stage.
Use Send Drawings when you have files but not a full RFQ.
This is best for sketches, CAD files, part photos, or early technical notes that need a first look before deeper quote intake.
Send Drawings →Use Request a Quote when the project is more defined.
This is better when you can provide quantity expectations, material context, tooling needs, timeline, and production goals.
Request a Quote →Use DFM Support when the design is still evolving.
If geometry, wall thickness, draft, material, or tooling practicality are unclear, a DFM path may be more useful before quote discussion.

What buyers usually need to clarify.
The most useful quote requests connect files, materials, quality expectations, and commercial context instead of treating each item separately.
CAD and drawings
Part geometry, drawing notes, revisions, and marked-up details help the project move from vague inquiry to reviewable package.
Resin and application
Material direction, performance requirements, finish expectations, and operating environment help shape the quote conversation.
Tolerances and inspection
Critical dimensions, cosmetic surfaces, approval requirements, and quality notes should be visible before review.
Why preparation matters
Better information helps avoid weak quote conversations.
Injection moulding quotes can become unclear when critical details are missing. A project may look ready on the surface but still need clarification around tolerances, material performance, cosmetic expectations, production volume, tooling assumptions, or quality requirements.
Confidentiality guardrails
Send enough to review, but protect sensitive files.
Do not submit highly sensitive, export-controlled, regulated, defence-related, or proprietary files unless an appropriate NDA or written agreement is in place. If confidentiality needs to be discussed before sharing files, use the contact path first.
Ready to move forward?
Send the project details you have.
Whether the project is quote-ready or still developing, the next step is to share enough information for a useful manual review.
RFQ questions
Common questions before sending project information.
What should I send for an injection moulding RFQ?
Useful starting information includes 3D CAD files, 2D drawings, estimated quantities, material preferences, application details, tolerances, cosmetic requirements, timing goals, and any existing tooling information.
Can I request a review if I only have sketches or early notes?
Yes. Early files can still be useful. The review may focus on project stage, missing information, DFM questions, and what would be needed before a more complete quote conversation.
Is submitting an RFQ the same as receiving a binding quote?
No. A submission through InjectionMouldHub is for manual review only. It does not create a binding quote, manufacturing agreement, NDA, agency relationship, or obligation to proceed.
Should I send confidential files before an NDA?
Do not send highly sensitive, export-controlled, regulated, or proprietary files unless the right NDA or written agreement is in place. Use the form to indicate if NDA-friendly handling is needed before sharing sensitive details.
Should I request a quote or send drawings first?
Request a quote if the project has defined quantities, materials, timing, and production goals. Send drawings if you have files or partial details but need help identifying the right route first.
