What Does PPAP Submission Cost — and Who Pays for It?

PPAP (Production Part Approval Process) is the automotive industry’s evidence package that a supplier can produce parts to specification at rate — and the cost of assembling that package falls on whoever owns the submission obligation, which is almost always the molder, not the mold maker. The mold maker’s cost is the dimensional report, material records and trial evidence the PPAP requires; the molder’s cost is the process validation, capability studies and the submission itself.

Cycle time — The total time for one injection molding cycle: injection + packing + cooling + mold open/close + ejection. Typical range: 15–60 seconds. Cycle time determines production rate and cost per part — reducing cycle by 5 seconds saves 10–15% annual production cost. See also related guide.

Key Facts

  • PPAP has five submission levels, with Level 3 the default for most automotive programs — requiring dimensional results, material and performance test records, process flow, control plan and initial process study.
  • The mold maker delivers the evidence the PPAP needs from the tool: dimensional reports against the drawing, material lot records, trial videos and first-article measurements — the submission package is assembled by the molder from these inputs.
  • PPAP cost is not a line item on the mold quote; it is a program cost that appears in the molder’s piece price and the toolmaker’s evidence package, with both sides knowing what they owe before the deposit.

    What PPAP Actually Requires from the Tool

    PPAP Element Toolmaker’s Contribution
    Dimensional results First-article CMM report against the drawing, with every feature measured and recorded
    Material records Resin lot numbers, steel grades and heat treatment records for the tool
    Process flow and control plan The molder owns these; the toolmaker provides the process window and setup sheet as inputs
    Initial process study Capability data (Cpk/Ppk) from the molder’s production runs; the toolmaker’s trial data supports the baseline
    Sample parts Production-intent parts from the qualified tool, measured and retained as evidence

    Where the Cost Actually Lands

  • The mold quote covers the evidence package: dimensional reports, material records, trial documentation — the toolmaker’s deliverables that feed the PPAP submission.
  • The molder’s piece price covers the submission itself: process validation, capability studies, control plan and the administrative burden of assembling and submitting the package to the OEM.
  • When the program requires PPAP Level 3 or higher, both sides price it in advance — the toolmaker’s evidence scope and the molder’s submission cost — so neither discovers the obligation after the steel is cut.
  • Non-automotive programs may request PPAP-style documentation without the formal submission; the cost structure is the same, but the administrative overhead is lower.

    • How the Quotation Should Present It

    A PPAP-aware quotation separates the toolmaker’s evidence deliverables from the molder’s submission obligation. The mold quote lists the dimensional report scope, the material records included and the trial documentation — the inputs the molder will use. The molder’s piece price quote then references the PPAP level required and includes the submission cost in the per-part number. When both sides price their obligations before the deposit, the program runs without surprise invoices at the submission milestone.

    Frequently Asked Questions

    Does the mold maker submit the PPAP?

    No — the molder submits, because PPAP validates the production process, not just the tool. The mold maker delivers the evidence the submission requires: dimensional reports, material records and trial documentation. The molder assembles those inputs with their process validation and submits to the OEM.

    What if the program changes the PPAP level after the tool is built?

    Moving from Level 2 to Level 3 adds capability studies and control plan requirements — costs the molder absorbs in piece price, not the toolmaker. Moving from Level 3 to Level 5 adds additional approval requirements that may require re-trial. The quotation should state the assumed PPAP level; changes after the fact are change orders, not surprises.

    Can non-automotive programs use PPAP?

    Yes — medical, aerospace and industrial programs sometimes request PPAP-style documentation without the formal AIAG submission. The evidence requirements are similar (dimensional reports, material records, process validation), but the administrative burden is lower. The cost structure remains the same: toolmaker provides evidence, molder provides validation.

    Key Takeaways

    1. PPAP is the molder’s submission obligation; the mold maker delivers the evidence package (dimensional reports, material records, trial documentation) that feeds it.
    2. Both sides price their PPAP obligations before the deposit — the toolmaker’s evidence scope in the mold quote, the molder’s submission cost in the piece price.
    3. Changes to the PPAP level after the tool is built are change orders; the quotation should state the assumed level explicitly.
