Engineering Review Before Tooling
Free DFM Review Before Tooling Investment
Good injection molding projects start before mold steel is cut. Moldinno reviews your drawings, material direction, part structure and production assumptions so you can reduce tooling risk before committing budget.
Why DFM Matters
DFM is not decoration. It is risk control.
Many sourcing mistakes happen because a supplier quotes quickly without understanding the part. We use DFM review to identify questions that affect mold cost, sample success, part stability and production repeatability.
For overseas buyers, this gives a clearer basis for comparing quotations. It also helps your engineering, purchasing and management teams understand what is included, what still needs confirmation and where the risk sits.
Before quoteIdentify missing details and quotation assumptions.
Before moldReduce design, gate, parting-line and ejection risk.
Before trialDefine sample review and approval checkpoints.
Before productionClarify quality, packaging and shipment expectations.
DFM Checklist
What We Check Before Mold Making
A practical DFM review focuses on the details that affect tooling decisions, trial samples and production stability.
Moldability
Draft angle, parting line, ejection method, slider/lifter needs, gate location and visible surface concerns.
Material direction
ABS, PC, PP, PA, POM, TPU, PPSU and other materials are reviewed against application, heat, strength and cost.
Tolerance risk
Critical dimensions, assembly fit, deformation risk, shrinkage direction and how inspection should be controlled.
Surface standard
Texture, SPI finish, painting, printing, visible surfaces, weld-line sensitivity and cosmetic acceptance criteria.
Production assumptions
Target quantity, mold life, cycle expectation, packaging, shipment, documentation and testing requirements.
What to Send for Review
What to send for a useful DFM review
The more accurate the RFQ package is, the more useful our feedback becomes. If drawings are not ready, send samples, reference photos or a functional description first.

What You Can Expect From Us
We do not turn every RFQ into a long report. We first provide clear, practical feedback that helps you decide the next step.
Open questions list
We highlight missing information that may affect quote accuracy, tooling direction or production feasibility.
Risk notes
We identify visible design risks such as wall thickness imbalance, undercuts, thin features, ejection difficulty or cosmetic concerns.
Manufacturing route
We suggest prototype, CNC, soft tooling, production mold or full molding route according to your project stage.
Quote assumptions
We clarify what the quotation is based on: material, quantity, mold structure, surface finish, packaging and lead time.
Sample plan
We explain the likely sample path from tooling to T0/T1 review, modification and final approval.
Next-step action
We help define whether the project should move to quotation, prototype validation or design adjustment first.
