Pattern geometry
Identify passages, wall sections and the finished-part geometry.
Factory Tour · Process principles
Carry the geometry from pattern to finished casting.
Investment casting connects wax patterns, ceramic shells, alloy casting and final machining. Separate the near-net cast form from the interfaces that need further finishing.
The route and inspection scope are reviewed for the alloy, geometry and order.
Process relationships
- Wax pattern
- Ceramic shell
- Cast geometry
- Finished interface
Connect each stage to the finished-part requirements.
Define the requirement
Bring the drawing, material and acceptance inputs.
Alloy and condition
Provide the alloy specification, heat-treatment requirements and surface condition.
Finished interfaces
Mark cast versus machined surfaces, datums, sealing faces and dimensional acceptance.
Process principles
One geometry. Four connected stages.
The wax-pattern and shell route must support the final casting geometry and the agreed inspection access.
Pattern
Review pattern geometry, passages and the features that influence release from tooling.
Shell
Gated wax patterns receive ceramic layers before dewaxing.
Cast and finish
Confirm the alloy and casting route, then review removal of gates and surface residues.
Machine interfaces
Finish functional faces and verify the agreed dimensions and soundness.
Verification and records
Separate geometry, material and internal integrity.
Datum structure
Agree casting datums and CMM measurement of critical finished features.
Material condition
Review heat-level chemistry and the specified material or heat-treatment records.
Inspection scope
Define required surface or internal-integrity inspection before tooling. Reports and acceptance are scoped to the component.
Project review
Connect the route to your requirement.
Send the material or drawing definition, intended use and the acceptance records needed for review.
