Test medium and pressure
Identify the fluid or gas and the pressure applied to the tested part.
Sealing geometry
Pressure-Tight Die Castings.
Casting and machining routes developed around sealing faces, fluid passages and pressure integrity — with acceptance criteria agreed before tooling release.
Define the supplied condition, critical dimensions and acceptance plan in the drawing review. Published process references depend on material, geometry and the agreed order scope.
Agree the Leak Test Before Tooling.
Duration and acceptance
Define stabilisation, test duration and allowable leakage with units.
Process sequence
Review machining exposure, sealing surfaces and any approved impregnation route.
Production route, manufacturing responsibility, available documentation and acceptance criteria are confirmed for the particular product and order.
Manufacturing Scope
Sealing surfaces supported by defined leak tests.
Process
130–4,400T aluminum HPDC network with vacuum assistance where required
Machining
Sealing faces, ports, bores and threaded connections
Testing
Air-decay, pressure-drop or other agreed methods
Traceability
Lot-controlled inspection and nonconformance records
Feature review
Agree the seal path and the acceptance method.
The continuous groove, adjoining land and side port define different parts of the sealing interface. Identify the gasket contact, machined sealing surfaces and test connections on the same drawing revision.
Relate the test boundary to the supplied condition after machining and finishing. Acceptance needs the stated medium, pressure, duration and allowable leakage, together with any approved process sequence.

Frequently Asked Questions
Does die casting guarantee zero porosity?
No casting process should be described that way. We manage porosity risk through DFM, process selection, machining allowance and an agreed leak-test acceptance plan.
Can every part be leak tested?
Yes when the fixture, cycle time and acceptance criteria are defined. The test method and sampling level are included in the quotation.
