RFQ Readiness Checker: Is Your Package Ready to Send?

An incomplete RFQ is the fastest way to get padded pricing or no quote at all. Missing files, unspecified tolerances, or ambiguous volumes push suppliers to price conservatively for their assumptions, or to decline the bid.

Use the RFQ Template to structure the package. Use this checklist as the pre-send gate. For an interactive version, use the RFQ Readiness Scorer.

1. Files & Geometry

  • 3D CAD Model Attached: STEP (.step / .stp) format is generally preferred. Native CAD files are only acceptable if the supplier explicitly confirms compatibility.
  • 2D Drawing Included: Mandatory if any dimension has a specific tolerance requirement beyond a standard block tolerance.
  • DFM Variables Visible: Wall thickness, draft angles, and undercuts must be physically modeled or explicitly called out in drawing notes to prevent immediate design-for-manufacturing (DFM) delays.
  • Revision Control: The 3D model and 2D drawing share identical, current revision levels.

2. Material Specifications

  • Exact Resin Grade: Specify the exact family, grade, and any required fillers/modifiers (e.g., “Lexan 940 Polycarbonate,” not just “PC”).
  • Approved Substitutes: Note acceptable alternatives to mitigate supply chain delays or cost risks on the primary grade.
  • Color Requirements: State if the part is as-molded (natural/unpigmented) or specify a precise color standard (e.g., Pantone, RAL) or target match.
  • Regulatory Compliance: Explicitly state if the resin requires food contact (FDA), medical (USP Class VI), RoHS, or specific UL flame ratings.

3. Volume and Scheduling

  • Estimated Annual Usage (EAU): The total projected annual volume. Suppliers use this to determine optimal tooling cavitation and steel type.
  • First Order Quantity: The volume required for the initial production run.
  • Target Dates: Define separate deadlines for First Article Samples (T1) and full production parts.
  • Program Intent: State whether the RFQ is for prototyping, bridge tooling, or long-term production.

4. Tolerances and Quality Requirements

  • Critical-to-Function (CTF) Dimensions: Flagged on the 2D drawing with specific tolerances.
  • Cosmetic Standards: Define surface finish (e.g., SPI standards, Mold-Tech textures), acceptable witness marks (e.g., gate vestige, ejector pins), and clearly demarcate A-surfaces.
  • Acceptance Criteria: Cite specific inspection standards (e.g., “visual inspection at 18 inches for 10 seconds”) rather than vague terms like “high quality.”
  • Part Classification: Indicate if the component is structural, cosmetic, functional, or medical, as this dictates the supplier’s required quality control procedures.

5. Tooling Scope

  • Tooling Ownership: Explicitly state whether the buyer or the supplier retains legal ownership of the mold.
  • Quote Structure: Specify whether you need pricing for tooling only, parts only, or a complete package.
  • Cavitation Preference: Note if you require a specific cavity count, or explicitly state that the supplier should recommend cavitation based on EAU.
  • Target Tooling Budget: Optional, but providing a range focuses the supplier on realistic mold classes rather than over-engineering the proposal.

6. Commercial Terms

  • Incoterms and Delivery: Define the delivery terms (e.g., DDP, FOB) and destination, particularly for offshore sourcing.
  • Payment Terms: State requirements upfront if they deviate from standard terms.
  • Non-Disclosure Agreement (NDA): Confirm an NDA is executed if proprietary geometry is shared.
  • Cost Breakdown: Specify if you require tooling, piece price, and secondary operations to be itemized.

Pre-Send Decision

  • Send: All critical sections are complete; the supplier can quote the program accurately without guessing.
  • Send Conditionally: If gaps exist, attach a cover sheet detailing exactly what is unknown (e.g., “EAU is TBD, quote based on 10,000 units/year”) to allow conditional pricing.
  • Hold: If 3D files, materials, or EAU are missing, do not send the RFQ. Any quote generated will be functionally meaningless.

Buyer-side engineering explainer

Injection Molding RFQ Readiness: Send, Flag, or Hold

An RFQ should give suppliers enough controlled information to quote the same scope. Known gaps can be flagged, but missing core files, material intent, or volume can make quotes slow, padded, and difficult to compare.

PTA buyer review mode
Buyer review: connect the finding to evidence and a decision CAD + drawing Material intent Volume + timing Quality scope Commercial scope DECISION Evidence before release Static fallback: review the full evidence package before releasing the next buyer decision.

Static review summary: send when core scope is complete, send with flags when gaps are controlled and shared consistently, and hold when missing inputs prevent a useful comparable quote.

Step 1: Prepare the RFQ

Start with one controlled package and identify the person responsible for its current revision.

Step 2: Review files

Confirm the 3D model, 2D drawing, critical dimensions, and revision status agree before sending.

Step 3: Review material

State the required material intent and identify where substitution is allowed rather than leaving suppliers to guess.

Step 4: Review program intent

Suppliers need annual volume, first-order intent, tooling objective, and realistic timing to propose comparable solutions.

Step 5: Review acceptance scope

Flag critical dimensions, appearance zones, inspection expectations, secondary operations, ownership, and delivery scope.

Step 6: Flag known gaps

A visible, controlled gap is better than an invisible assumption. State what is open and how suppliers should quote it.

Step 7: Send or hold

Send complete packages, send conditionally when gaps are controlled, and hold when missing core inputs prevent a useful quote.

This buyer-side explainer is an RFQ preparation framework, not a guarantee that every supplier has enough information to quote. Requirements vary by part, program, supplier, and industry; verify the final package and open assumptions before issue.
