Overview
Molding and casting cover repeatable plastics via injection, elastomers via silicone tooling, and net-shape metals via die casting. Pick the dedicated guide below for process-specific DFM; use this page for cross-cutting requirements shared across suites.
- Injection moldingThermoplastic tooling, draft, materials, and IM economics.
- Silicone moldingLSR, RTV, and soft-tool silicone workflows.
- Die castingHigh-pressure zinc and aluminum casting.
Required files
| File | Use | Notes |
|---|---|---|
| STEP/STP | Primary molded or cast geometry | Required for tooling and manufacturability review. |
| PDF drawing | Material, tolerances, texture, inserts | Strongly recommended before tooling lock. |
| Reference sample | Cosmetic or fit benchmark | Useful when matching an existing part. |
Shared design themes
- Uniform wall thickness reduces sink in plastics and porosity risks in metals.
- Draft and radii should be planned with parting lines and gate placement.
- Critical fits may require secondary machining regardless of base process.
Quote-dependent values
Tolerance, finish, material, inspection, and lead-time values are practical guidance. Final commitments depend on supplier selection, drawings, and order review.
