Die Casting with CNC Machining for Metal Parts
6CNC combines die casting, secondary CNC machining, and agreed finishing for repeat metal component production. We review alloy selection, tooling, casting geometry, and critical machined features together so the manufacturing route supports your assembly requirements.
- Aluminum, zinc, and magnesium alloys
- Casting design and DFM support
- Secondary machining and inspection
Why Work with 6CNC?
Work with 6CNC on the complete component, from the casting concept to critical CNC-finished surfaces. Our manufacturing background helps connect tooling decisions with machining access, dimensional checks, finishing, and the production schedule.

Use Die Casting Where Repeat Demand Supports Tooling
Die casting can suit stable designs with recurring demand and complex near-net geometry. 6CNC reviews the tooling investment and downstream operations against the expected production volume.
Housings and enclosures
Combine walls, ribs, mounting features, and interfaces in a formed component. Identify functional surfaces that will need machining or specific inspection.
Repeat industrial components
Share the production quantity and expected repeat demand for brackets, frames, and equipment parts. Consistent geometry makes a controlled process more practical.
A route beyond prototypes
When the design is changing or volumes are low, CNC machining may be a more flexible starting point. We review both routes before committing to tooling.
Select the Alloy and Casting Route Together
6CNC supports aluminum, zinc, and magnesium alloy enquiries. Specify the required grade and application; the alloy, component geometry, and tooling concept determine the proposed process.
| Option | What to review |
|---|---|
| Aluminum alloys | Commonly considered for lightweight housings and industrial parts. Cold-chamber casting is a typical route; confirm mechanical, finish, and corrosion requirements. |
| Zinc alloys | Often selected for detailed parts and fine features. Hot-chamber casting is a common route; review component weight, finish, and functional needs. |
| Magnesium alloys | An option where weight is a design priority. Confirm the grade, process suitability, surface protection, and operating requirements. |
| Hot- and cold-chamber options | 6CNC reviews the process against the alloy and part. Do not select a route solely by cycle speed without considering tooling and downstream operations. |
Resolve Casting and Tooling Details Before Manufacture
Our DFM review covers the part as a casting and as a finished component. We identify design issues early, while proposed changes can still be discussed before tooling.
- Walls, ribs, and transitions
Review thick sections and abrupt changes that can affect metal flow and solidification. Keep reinforcement and material distribution aligned with the design purpose. - Draft, radii, and release
Define the release direction and review internal corners, draft, and undercuts. Tool access and ejection requirements can affect the component geometry. - Machining allowance
Identify surfaces that will be machined after casting. Allow for workholding, datum establishment, and material removal on the drawing. - Porosity-sensitive areas
Flag sealing faces, pressure-containing areas, and any internal-quality requirements. Agree the relevant acceptance criteria and checks before production.
Finish Critical Features with CNC Machining
6CNC integrates secondary machining where as-cast features do not meet the final requirement. This keeps precision work focused on the surfaces that control fit and assembly.
Holes and threads
Define the final hole geometry, thread specification, and positional requirements. Review access and machining references with the casting design.
Mating and mounting faces
Identify flatness, fits, and datum relationships needed for assembly. These requirements guide fixtures and the sequence of operations.
Finishing and inspection
Specify the required surface treatment and the dimensions to check after it. Agree inspection and documentation scope as part of the complete component quotation.
From Tooling Review to Repeat Batches
6CNC coordinates tooling and production planning around defined approval points. Clear sample acceptance and controlled revisions help prevent uncertainty when the production order is released.
01
Review requirements
Send CAD, a controlled drawing, alloy grade, quantities, critical features, finish, inspection requirements, and delivery targets.
02
Confirm tooling and process
Review casting DFM, the proposed route, secondary machining, and sample plan before tooling manufacture proceeds.
03
Evaluate initial parts
Check agreed dimensions, appearance, and application-specific requirements. Record feedback and approve any corrections before batch release.
04
Produce and deliver
Confirm the production revision, batch inspection, packaging, and delivery schedule. Review subsequent engineering changes before repeat manufacture.
Compare the Cost of a Finished Component
A lower casting price does not always mean a lower delivered-part cost. 6CNC considers tooling, material, secondary machining, finishing, and inspection in the project scope.
01
Tooling and revisions
Part complexity and release features influence the tooling investment. Late changes can affect both the tool and downstream fixtures, so resolve key design decisions early.
02
Volume and recurring cost
Use realistic order quantities and repeat demand. Higher output can spread tooling cost, but machining and finishing remain part of each component.
03
Low-volume enquiries
6CNC can review lower-volume casting runs. We compare feasibility and tooling economics with machining rather than apply one fixed quantity threshold to every part.
04
Delivery planning
The first delivery must account for tooling, trials, approval, and production. Repeat schedules depend on the approved configuration, material supply, operations, and required checks.
Die Casting FAQ
Which die casting materials does 6CNC support?
We review aluminum, zinc, and magnesium alloy projects. Include the required grade and application so the casting route, finishing, and inspection requirements can be confirmed.
When should I choose die casting over CNC machining?
Consider casting when the design is stable and repeat demand justifies tooling. CNC machining can be more practical for development parts, frequent revisions, or quantities that do not support the tooling investment.
Can die-cast parts include tight-tolerance features?
Yes, where the proposed process can meet the requirement. 6CNC can add secondary CNC machining for critical holes, threads, and mating surfaces; tolerances are reviewed feature by feature.
Does 6CNC provide DFM support?
Yes. We review wall distribution, draft, release features, radii, and machining requirements before tooling. DFM helps address manufacturing risks without replacing your design approval.
Can you review a low-volume die casting order?
Yes. Send the quantity and expected repeat demand. We review the tooling economics and process feasibility and can discuss CNC machining as an alternative.
What affects the lead time?
Tool manufacture, trials, sample approval, corrections, casting, machining, finishing, and inspection all contribute. The first production batch and repeat orders have different scheduling requirements.
What if my component must seal or hold pressure?
Identify the requirement on the drawing and in the enquiry. Internal quality, machined sealing surfaces, and any testing need explicit review and agreement; they are not implied by a dimensional inspection.
What information is needed for a complete quote?
Provide CAD, drawings, alloy, quantities, annual or repeat demand, finish, critical dimensions, quality requirements, and the target date. Include any sample approval or documentation requirements.
