Part architecture
Review wall transitions, draft, ribs, bosses, undercuts, shutoffs, shrink behavior, assembly interfaces and critical dimensions before the tool direction is released.

Engineering before tooling
SRRP connects part function to moldable geometry, thermoplastic resin, tooling decisions and first-article evidence—so engineering questions are visible before the program reaches production.
The brief becomes visible
Clear inputs first
01 / INPUTS
Drawing, resin, volume and use environment
02 / REVIEW
DFM notes, risk points and tooling route
03 / RELEASE
First article, quality criteria and repeat handoff
01 / Engineering decisions
Three engineering decisions
DFM is not a generic checklist. Geometry, material behavior and tool strategy must be reviewed together against the application, annual demand and customer approval plan.
02
Material route
Translate temperature, load, chemical contact, UV exposure, flame needs, appearance and cost into a resin shortlist that can be verified with the application.
SERVICE / RESIN / FINISH / COST
03
Tool + approval plan
Align parting, gate, cooling, venting, ejection, cavity strategy, first-article checks and correction loops before production timing becomes a commitment.
GATE / EJECTION / TRIAL / RELEASEEngineering, tooling and production workflow · project team, tools and approval records are identified in the quotation
02 / RFQ clarity
A complete RFQ
The goal is not a longer form. It is a cleaner first conversation — enough context for engineering to identify risk, recommend a route and return useful next steps.

Engineering gates 03–08
Project intake and quotation are master gates 01–02. These six engineering-to-supply gates continue the same lifecycle without creating a second numbering system.
Confirm application, CTQs, environment, volume, appearance and release evidence. Gate output: requirement and assumption register.
Resolve wall, draft, ribs, bosses, shrink, resin behavior and assembly interfaces. Gate output: closed DFM actions and resin basis.
Define parting, gate, cavity, cooling, venting, ejection, mold life and ownership. Gate output: reviewed mold specification.
Build, bench, sample and close trial defects through documented correction loops. Gate output: traceable samples and issue closure.
Establish a repeatable setup and process window, then approve fit, appearance, function and critical dimensions. Gate output: approved part and released process basis.
Control material, startup, in-process checks, traceability, packing, mold condition and engineering changes. Gate output: lot release and controlled lifecycle records.
PRODUCTION RELEASE
04 / Make the factory part of the brief
Review the workflow
A dependable supplier should show more than polished parts. It should explain who owns the brief, where decisions are recorded, how the first article is judged and what remains controlled when the project becomes repeat production.
