A CONTROLLED PROJECT PATH
How an Injection Molding Project Moves From RFQ to Delivery
Every stage should answer a different question. The customer supplies requirements and approvals; Startup Molding supplies manufacturing review, defined outputs, and evidence for the next decision.
1–4: Define the project
| Stage | You provide | We provide / decision |
|---|---|---|
| RFQ | CAD, drawings, requirements, quantities, market, and timing | Scope review and clarification list |
| File review | Latest revision and missing technical context | Feasibility screen and information gaps |
| DFM | Responses to geometry, material, cosmetic, and assembly questions | Findings, risks, recommendations, and approval items |
| Quotation | Confirmed commercial and technical basis | Defined tooling, samples, production, inspection, and terms |
5–8: Design and build the tool
| Stage | You provide | We provide / decision |
|---|---|---|
| Design confirmation | Approved part revision and DFM decisions | Release baseline for tooling |
| Mold design | Review and approval at agreed gates | 3D tool concept and documented open points |
| Tool manufacturing | Timely answers to controlled questions | Tool build progress and preparation for trial |
| T1 samples | Testing plan and receiving details | Molded samples, trial observations, and agreed inspection evidence |
9–13: Validate, approve, and scale
| Stage | You provide | We provide / decision |
|---|---|---|
| Customer testing | Fit, function, assembly, and application feedback | Issue classification and response plan |
| Corrections | Approval for design or specification changes | Controlled process, tool, or design correction |
| Approval | Written release against agreed criteria | Approved baseline and production readiness |
| Pilot / mass production | Orders, forecast, packaging, and release schedule | Controlled batches, inspection, packing, and records |
| Delivery | Shipping instructions and import responsibilities | Shipment preparation and agreed documents |
Approval gates protect both teams
An approval gate records the revision, assumptions, evidence, and person authorized to proceed. It prevents a fast-moving project from treating an unanswered question as permission.
Frequently Asked Questions
Who approves DFM and mold design decisions?
The customer should nominate a technical approver. Startup Molding documents the manufacturing recommendation; the customer approves product requirements and agreed tradeoffs.
What happens when the design changes after tooling starts?
The change is reviewed for tool, schedule, sample, inspection, and commercial impact before implementation. The revised file and approval become part of the project record.
When is a tool released for production?
After the agreed sample, dimensional, functional, cosmetic, and documentation requirements are accepted in writing.
