Compare die casting and squeeze casting against the same finished drawing, production demand and acceptance requirements. Squeeze casting may be worth evaluating when internal integrity or heat treatment drives the decision; neither route is universally preferable.
Start with the job the part must do
A casting route should be selected against the finished component’s requirements. A process name alone does not establish whether a part will meet its mechanical, dimensional or sealing specification.
| Question | What to compare |
|---|---|
| Is internal integrity critical? | Discuss discontinuity limits and inspection methods |
| Is heat treatment required? | Confirm alloy, process and property requirements |
| What geometry is needed? | Review wall sections, draft, interfaces and machining allowance |
| What volume is expected? | Compare tooling and finished-part costs at the same demand |
| How will acceptance be decided? | Agree samples, test methods and release criteria |
Ask for a drawing-based assessment
CEX offers both aluminum die casting and squeeze casting. Its published squeeze-casting capability includes suitable alloys that can be considered with T6 heat treatment. Use these capabilities as a starting point for a specific engineering review.
Compare the complete manufacturing route
A useful comparison includes tooling, casting, machining, heat treatment where applicable, finishing and inspection. Confirm that each quotation refers to the same drawing revision and acceptance criteria.
Use a like-for-like comparison
| Criterion | Die casting review | Squeeze casting review |
|---|---|---|
| Geometry | Review cast features, tooling access and required machining | Review the same features against the proposed pressure-solidification route |
| Performance | Confirm the selected alloy, process and test requirements | Confirm the selected alloy and any heat treatment; validate the actual component |
| Internal integrity | Define discontinuity limits and any functional leak test | Apply the same acceptance criteria; do not assume zero defects |
| Economics | Include tooling, secondary work, inspection and demand | Include tooling, thermal processing where needed, machining and inspection |
A practical review sequence
- Freeze the functional requirements and identify what may be redesigned.
- Request a manufacturing review for each candidate route using the same drawing revision.
- Separate one-time tooling and validation costs from recurring part costs.
- Agree sample tests before commissioning tooling.
- Compare approved finished components, including any changes to machining or inspection.
Avoid three misleading shortcuts
First, do not compare a finished casting quotation with a price that excludes machining or inspection. Second, do not treat a handbook property as an acceptance result for your component. Third, do not assume that a process change leaves the design unchanged: datums, sections and tooling features may need review.
Example decision: a machined pressure housing
For a housing with a leaking machined bore, start by documenting the leakage location, test conditions and current machining sequence. Ask whether the present process can meet the agreed limits and whether an alternative route should be sampled. Compare both on the same leak and dimensional requirements. This is a review scenario, not a reported customer outcome.
Further technical reading
These references support further study; they do not certify a CEX component. Use the applicable project specification for acceptance.
