What This File Freezes for Supplier Review Before Steel Cut

Supplier Control Engineer reviewing resin sheet with CTQ timing and shrink verification fields

This controlled review sheet aligns part, resin, shrink, and CTQ inputs to reduce missing-data issues. By requiring this file before steel cut release, procurement teams can verify supplier assumptions against engineering facts before T1.

The sheet defines specific fields like exact resin grade, directional shrink basis, CTQ items, measurement timing, and drawing revision baseline.

Material & Physics

Requires declaration of the exact resin manufacturer grade and separate entry of flow vs transverse shrink basis to account for fiber orientation, warpage, and flatness risk before tooling release.

Critical Controls

Defines listed CTQ / KPC items with required measurement timing (such as 24 h or 48 h conditioning) and verification method like CMM with fixture where required.

Review Chain

Establishes reviewed-by accountability, drawing revision baseline, and controlled engineering update records before steel cut release to reduce communication errors.

What Is Included in the Part & Resin Data Sheet Download Package

The template is structured into four control sections so resin, shrink, CTQ, and measurement assumptions are frozen before steel cut and tooling release. These sections let buyers and engineers verify critical data points before supplier approval.

Section Key Fields, Control Inputs, and Review Data
Section A Document ID, Prepared/Reviewed ownership, Drawing Revision, Annual Volume, and Project Baseline.
Section B Right resin grade selection criteria, exact manufacturer, UL94 rating at thickness, and drying conditions for material approval.
Section C Flow and transverse datasheet shrink, applied shrink basis, regrind limit, and warpage risk mode review.
Section D CTQ / KPC list, tolerance feasibility for molded dimensions (TFL), and measurement method such as CMM with fixture.

Why This Sheet Reduces Supplier Risk Before Tooling Approval

Engineer reviewing drawing revision and CTQ verification sheet before tooling approval

A buyer can use this sheet to verify that the supplier is working from the released drawing, defined resin inputs, and controlled CTQ conditions.

A qualified supplier should be able to confirm drawing revision baseline, resin grade, directional shrink basis, CTQ method, and timing against the released drawing before T1.

The primary goal of the Part & Resin Data Sheet is to eliminate ambiguity. By documenting every critical variable in one place, we bridge the gap between engineering intent and manufacturing reality, ensuring procurement teams have the objective data needed to hold suppliers accountable before any steel is removed.

Prevents Resin Grade Ambiguity

Requires the exact resin grade name, such as Sabic Cycoloy CY6110, and supports validation against material certification. Material substitution then requires formal validation evidence before tool approval.

Exact Grade Name

Prevents Single-Shrink-Value Mistakes

Requires separate flow and transverse shrink entries to identify anisotropic material behavior. The sheet includes risk notes tied to GF orientation and warpage mode so tolerances are reviewed against realistic non-uniform shrinkage.

Directional Shrink Basis

Prevents CTQ Timing Disputes

Establishes timing and conditioning requirements, such as measurement 48 h after molding at defined ambient conditions (23°C / 50% RH). This prevents decisions from being made on uncontrolled timing that ignores stabilization.

24 h / 48 h Timing

Forces Revision-Controlled Review

Fits into a controlled engineering change workflow capturing reviewed-by ownership and revision history. This prevents revision drift and uncontrolled resin changes during production.

Revision History

When You Should Use This Template

Critical Phase: DFM & Tooling Release

This sheet is mandatory before DFM kickoff and steel cut release. It freezes drawing revision, resin grade, shrink direction, and CTQ baseline before steel cut.

Change Control: Material Substitution

Required before approving resin substitution or color change. Minor grade changes within the same family shift shrink behavior and require CTQ feasibility to be reviewed again.

Quality Gate: First Trial Preparation

Essential before T1 trial planning. If CTQs, assembly fit, flatness, or cosmetic risk matter, measurement timing, conditioning, and method (CMM/fixture) must be locked here.

Industry-Specific Validation Triggers

Automotive

Complete this sheet before PPAP dimensional submission and capability review so supplier measurement timing, resin grade, and CTQ logic match the evidence package.

Medical Devices

Lock this sheet before validation evidence for tooling approval is written into IQ/OQ/PQ protocols to maintain a validated manufacturing state.

Electronics / UL Parts

Verify this sheet before UL rating at thickness is accepted. This prevents compliance failures caused by material grade drift or regrind above the approved limit.

When NOT to Use This Template

Concept Phase

✕ Do not use this sheet at RFQ stage if drawing revision, resin grade, and CTQ agreement are not yet frozen. Use an injection mold quotation checklist instead.

Prototype Builds Without Frozen Inputs

✕ Do not use this sheet for simple prototype builds when CTQs, shrink basis, and measurement timing are still under evaluation and not yet controlled.

Full Tooling Specs

✕ Use an injection mold specification sheet when cavity count, mold steel, runner type, and machine limits are the primary controls to be approved.

What Each Field Means — and Why Buyers Should Care

This sheet defines the drawing, resin, shrink, CTQ, and timing inputs that procurement and engineering must review together during supplier evaluation to verify technical assumptions before tool approval.

Field / Requirement
Why it matters for supplier review
Part No., Drawing Rev, Annual Volume & Use Case
This aligns the drawing revision, part use case, and annual volume so tool size, cavity strategy, and supplier quoting assumptions start from the same correct engineering baseline.
Exact Resin Manufacturer and Grade
Defining the exact resin grade, such as Covestro Makrolon 2405, improves supply chain traceability and supports material certification, lot traceability, and supplier approval control to prevent hidden resin substitution.
Flow vs. Transverse Shrink
This helps review anisotropy and warpage risk by using our resin selection and shrink behavior guide to review how directional shrink affects functional dimensions and hole positions.
GF Content, UL Rating, Drying & Warp Risk Mode
This requires the supplier to confirm GF content, UL94 rating at the specified wall thickness, drying condition, and warp mode for moisture-sensitive or reinforced resins before steel release to ensure tool life and flammability compliance.
CTQ / KPC, TFL Level, and Measurement Method
This defines the TFL level so requested tolerances are reviewed as standard, controlled, or risky. Pre-defining the first article dimensional reporting format ensures alignment on measurement tools such as caliper versus CMM or fixture inspection.
Measurement Timing & Risk Notes
For hygroscopic or high-shrink materials, defining timing such as 24 h post-molding at controlled ambient or conditioning conditions avoids false CTQ rejection caused by measurement before dimensional stability is reached.

Tolerance Feasibility: What This Sheet Helps You Flag Early

If a supplier is unwilling to assign a Tolerance Feasibility Level (TFL) before steel cut, it usually means dimensional responsibility has not been aligned. This sheet records that alignment before tooling release.

Typical

Commercial

Standard tolerances achievable with routine process control and standard dimensional verification.

Capable

Precision

Achievable through optimized DFM, controlled mold temperature, and a tool build matched to the tolerance target.

Risky

Fine / Critical

High dimensional risk. May require dedicated fixtures, steel-safe planning, or cavity-separated reporting.

Why TFL Must Be Agreed Before Steel Cut

Finding out at T1 that a tolerance is classified as Risky usually leads to delay, rework, and added tooling cost. Before steel cut, the supplier should classify each critical dimension using material, geometry, shrink behavior, and measurement method as the review basis.

Using this sheet requires the supplier to review your tolerance targets against what tolerances can actually be achieved in injection molding based on material choice and part geometry. This pre-steel review ensures that any Risky dimension has a defined DFM change or steel-safe strategy defined before steel cut.

The Importance of Cavity-Separated Data

For multi-cavity tools, a single "average" dimensional report is insufficient for critical parts. The TFL logic in this sheet establishes whether PPAP dimensional evidence for multi-cavity molded parts will be required later in the process.

Early alignment ensures the supplier prepares the necessary CMM fixtures and measurement programs before T1 onward. For high-precision tools, cavity-separated reporting with cavity ID is mandatory when CTQs cannot be judged reliably from averaged data across the tool.

Supplier Validation Evidence: confirmed Before Tooling Approval

This section lists the objective evidence a supplier should provide in addition to the completed sheet. Use this checklist to verify resin control, CTQ measurement, timing conditions, and revision-controlled approval.

Metrology Readiness

  • Document measurement method, CMM program, or fixture readiness for Capable or Risky CTQs.
  • Show cavity-separated or feature-level dimensional evidence rather than averaged data across the tool.

Validation Protocol

  • Agree on timing and conditioning requirements, such as 24 h or 48 h at defined ambient conditions, before T1.
  • Provide validation evidence for tooling approval including dimensional reports and capability evidence.

Common Questions About Part & Resin Data Sheets

What should be included in a part and resin data sheet?

A part and resin data sheet should include drawing revision, exact resin grade, color, UL94 rating at thickness, regrind limit, flow and transverse shrink values, CTQ entries, measurement method, timing condition, and reviewed-by ownership so supplier review and T1 decisions use the same baseline.

Why does flow vs transverse shrink matter?

Flow vs transverse shrink matters because semi-crystalline and fiber-reinforced resins do not shrink equally in different directions. Ignoring this anisotropic behavior leads to inaccurate tool offsets, resulting in out-of-tolerance positions, flatness issues, and unexpected warpage that single-value shrink assumptions cannot predict or control effectively.

When should molded CTQs be measured?

Molded CTQs should be measured only after achieving dimensional stability, typically 24–48 hours post-molding at controlled ambient conditions (23°C / 50% RH). Measuring too early leads to false rejects or accepted parts that later drift out of specification after stabilization. For critical CTQs, measurement must follow a defined CMM or fixture inspection method.

Is this sheet enough for PPAP or medical validation?

This sheet is a control input for technical alignment, not a complete validation package. For PPAP or IQ/OQ/PQ programs, this sheet must be supported by FAI, PPAP records, material certification (CoC), cavity-separated dimensional reports, and capability evidence where required. Review our full validation evidence beyond this sheet for more details.
