| Check Item | What the Review Addresses |
|---|---|
| Wall Thickness | Thick-to-thin transitions, filling, cooling, sink and warpage risk |
| Draft and Ejection | Draft, texture allowance, ejector strategy and potential part damage |
| Gate and Weld-Line Considerations | Candidate gate areas, filling balance, visible surfaces and functional risk |
| Parting Line and Shutoffs | Flash risk, appearance impact, sealing features and mold complexity |
| Undercuts and Actions | Slides, lifters, collapsible cores, manual inserts or design alternatives |
| Material Inputs | Candidate resin grade, shrinkage, environment, performance and supplier data |
| Tolerances and CTQs | Functional dimensions, datum strategy, measurement method and realistic capability |
| Assembly Interfaces | Fits, gaps, snap features, screws, inserts, sealing and tolerance stack-up inputs |
Send the available product brief, 3D CAD, 2D drawings, prototype photos, mating-part information, target resin or performance requirements, estimated volume, target market and the questions you need the next prototype or molded sample to answer. We will identify missing inputs before recommending a path.
Not always. The right method depends on design maturity, required material fidelity, quantity and the risk being tested. A 3D print, CNC prototype, soft tool or prototype injection mold may each be appropriate. We compare the options before recommending additional tooling investment.
We can sign an NDA before files are shared. Project access, approved recipients, subcontractor disclosure, file retention and return or deletion requirements can be defined in the agreement. Please identify any special security requirements before transfer.
We compare each finding with the approved DFM, mold design, drawing, resin and acceptance criteria. Confirmed mold-workmanship corrections are handled according to the tooling agreement. Product-design changes, new features, material changes or revised requirements follow the agreed engineering-change process.
The decision depends on geometry, material, required properties, quantity, product life, tooling budget, unit-cost target and validation needs. There is no universal 500-piece threshold. We compare the intended outcome with prototype, machining, soft-tooling and production-tooling options before recommending injection molding.
