Function and interfaces
A pump or valve housing needs a specified fluid, operating conditions, sealing arrangement and pressure boundary. Confirm whether the selected alloy and die-casting route can satisfy those requirements before tooling. This application page does not assign a pressure rating or imply approval for every fluid or safety category.
Casting and machining review
Map machined ports, seal grooves, bearing seats and minimum remaining walls. Check core release and internal cleaning access. Define leak or pressure testing on the supplied state, including plugs and sealing components where applicable. A surface coating or unspecified repair must not be used as an assumed cure for connected porosity.
Requirements to define
| Interface | Review requirement |
|---|---|
| Fluid boundary | Medium, temperature and pressure conditions |
| Ports and seals | Thread, land geometry and wall remaining |
| Internal passages | Core access and residual cleanliness |
| Acceptance | Defined finished-state test and limits |
Example of a project decision
A body tested before port machining may expose a new leak path afterward. Place the final acceptance test after the operations that change the boundary.
Information for a quotation
Send the controlled 3D model and drawing, material specification, finish, order quantities and delivery needs. Include mating parts, critical characteristics and required test records. The quotation should identify the casting, machining, finishing and inspection scope, together with any open decisions. Request a drawing review.
