Checks, tolerances, convergence, uncertainty, or inspection evidence appropriate to the service.
A concise interpretation connecting the deliverable to the customer decision.
Input requirements
What to provide before work begins
Provide representative, clearly labelled inputs and identify the decision, feature or comparison that matters.
| Suitable input | Submission requirement | Planning note |
|---|---|---|
| Project input or design file | Provide the current design, objective, constraints and required deliverables for technical review. | Declare confidentiality, file, access or delivery constraints in advance. |
Objective: state the decision, comparison or acceptance criterion the work must support.
Handling and access: declare hazards, instability, confidentiality, file constraints or special logistics before dispatch or transfer.
Questions and answers
Common planning decisions
Short answers to issues that can change preparation, scope, timing or interpretation.
What inputs are needed for Vacuum Casting?
A production CAD file such as STEP, plus a dimensioned drawing for critical dimensions, threads, fits, and tolerances.
Which service option should I choose?
Start with Rigid, flexible, clear, coloured, or filled polyurethane; the final option is confirmed against the required decision and acceptance criteria.
What will I receive?
Typical outputs include vacuum-cast resin parts, silicone mould and master record, visual and dimensional inspection. Final files follow the confirmed reporting scope.
How long will it take?
Delivery timing is confirmed after the project inputs, scope and dependencies have been reviewed.
