Master and mold
Review the part geometry and the feature relationships that define its function.
Discuss master and moldVALUE-ADDED SERVICES / VACUUM CASTING
Prototype polymer parts with a defined casting and approval plan.
Discuss a master, mold, resin and the intended evaluation before a limited build. Record the dimensions and material characteristics that the sample should represent, plus any differences from a future production route.

CAPABILITY & SCOPE
Vacuum Casting capabilities & project scope
Discuss a master, mold, resin and the intended evaluation before a limited build. Record the dimensions and material characteristics that the sample should represent, plus any differences from a future production route. The reviewed drawing and quotation establish the actual manufacturing scope. Confirm any specific process qualification or documentation needed for supplier approval.
| Requirement | Specification / review basis |
|---|---|
| Part definition | Current 3D model and drawing; units, revision and controlling dimensions. |
| Geometry / envelope | Overall size, internal features and access reviewed for the actual manufacturing route. |
| Material | Exact grade, condition and declared alternatives; availability confirmed during quotation. |
| Quantity | Prototype, initial batch and expected repeat quantities considered separately. |
| Critical features | Datums, mating interfaces and the tolerances required for the function. |
| Surface condition | Finish, cosmetic surfaces, edge treatment and after-finish dimensions. |
| Secondary operations | Machining, joining, inserts or other operations identified and included explicitly. |
| Inspection | Measurement scope, sample size, reference system and record requirements. |
| Sample approval | Purpose, test conditions, acceptance criteria and responsible approver. |
| Tooling / setup | Any dedicated tooling, holding and agreed reuse or maintenance requirements. |
| Identification & packing | Part number, revision, batch information and surface protection as required. |
| Delivery conditions | Desired milestone, destination and shipping scope; confirmed in the quotation. |
Choose the process for your part.

VACUUM CASTING RESIN
Casting polyurethane
For prototype and limited-build polymer components cast in a silicone mold. Select a rigid, flexible or transparent polyurethane formulation to match the sample purpose.
- Grade / condition
- Specify the exact grade and confirm availability before release.
- What to confirm
- The actual resin datasheet, hardness, color, mold life, aging and test limits. ABS-like or rubber-like descriptions do not mean the resin is the same polymer as ABS or production rubber.
- Cost & timing
- Master preparation, silicone mold complexity and life, resin formulation, finishing and batch quantity.
Define the surface that reaches your assembly
Process surface
Agree the acceptable as-produced surface, edges and process marks.
Cosmetic treatment
Discuss the required texture, appearance and acceptance reference.
Functional finishing
Specify any treatment or secondary work required by the application.
THE FINISHED PART
Define the acceptance requirements.
| Requirement | Specification / review basis |
|---|---|
| General requirements | State the drawing standard, units and default requirements rather than assuming a blanket tolerance. |
| Functional interfaces | Mark fits, positions and features that control the assembled function. |
| Final material condition | Identify dimensions and properties that apply after treatment or conditioning. |
| Inspection basis | Agree methods, reference geometry, sample size and report format. |
| Appearance acceptance | Define visible faces, reference samples and permitted process marks where relevant. |
Design considerations before vacuum casting
Tooling & release
Clarify draft, parting and geometry that affects the tooling route.
Ribs & transitions
Review wall changes and load-bearing features with the selected material.
Machining allowance
Mark interfaces that need secondary machining and their final condition.
Inserts & assembly
Define added components and their placement or joining requirements.
Surface & appearance
Agree visible faces, acceptable process marks and any treatment.
Validation stage
Separate the prototype purpose from production release and acceptance.

Review this project ↗Connect quality requirements to each stage
Define the applicable acceptance requirements before release. Request any material, process, dimensional or test documents by scope and format. Availability and included work are confirmed for your order.
Before release
Resolve the controlling files, material, critical features and sample requirements.
During the project
Record changes and identify any approvals required before the next stage.
Before dispatch
Match records, identifiers, quantity and packing to the agreed handover.
QUESTIONS BEFORE RELEASE
Clear answers. A defined next step.
What should I send for a vacuum casting quotation?
Include the application, current files, material, quantity, finish and critical acceptance requirements. Mark provisional information and any alternatives you want reviewed.
Can I start before the design is final?
Yes. Identify what is fixed and the question to resolve. A preliminary discussion is distinct from an approved manufacturing release.
What dimensional capability applies to my part?
The feature, geometry, material and final condition determine the review. Provide functional tolerances and a datum scheme so the actual requirements can be assessed.
Can a sample be approved before a repeat build?
Specify its purpose, quantity, test conditions and acceptance criteria. Record what it validates and what remains open before production.
Are special records or tests included?
List the exact document or test, method and acceptance criteria. Confirm availability, responsibility and cost in the quotation.
How are changes after quotation handled?
Identify the new revision and changed requirements. Reconfirm their impact on work, price, verification and schedule before proceeding.
