The interfaces make it work.
THE RIGHT PROCESS / THE RIGHT STAGE
Plan beyond
the first part.
Die casting needs its own tooling and production plan. We consider the first order, expected repeat volume and the interfaces your component must hold.
Compare manufacturing routesValidate the interfaces first.
A CNC-machined prototype may help check fit or assembly while the casting route is reviewed. Material behavior and casting-specific risks need separate validation.

ILLUSTRATIVE PROCESS STUDY / YOUR DRAWING DEFINES THE REQUIREMENTS
Give the body a clear manufacturing brief.
Share the full model, alloy, quantity and appearance requirements. Review walls, ribs, draft and tooling considerations with the casting route.
Review your cast geometryIdentify the surfaces that must seal or locate.
Mark the faces that need machining, their datums and their finished tolerances. Agree allowance, access and the condition used for acceptance.
Review finished facesConnect the final features to the assembly.
Define bore fits, hole positions and thread callouts. Show the feature relationships needed for assembly and final inspection.
Discuss casting plus machiningSECONDARY CNC MACHINING
Precision where
it matters.
The finished-part drawing connects casting allowance, machining access and final inspection. Mark the surfaces that locate, seal or mount the component.
Faces that mate
Mating planes, gasket lands and seating surfaces. Define flatness, roughness and the reference that controls their relationship.
Bores that locate
Bearing seats and other functional bores. Specify size, fit, position and the relationship to the agreed datums.
Mounting that aligns
Hole patterns, threads and counterbores. Include complete callouts and the assembled position that matters.
Edges ready for handling
Define burr limits, edge breaks, cleanliness and protection. Identify surfaces that must stay free of coating or damage.
THE QUOTATION / A COMPLETE SCOPE
Know the investment.
Understand the part cost.
Keep tooling and recurring production costs visible. Agree what each stage includes before the program is released.
01
Tooling & changes
Tool scope, ownership, sample plan, maintenance, storage and engineering-change terms.
02
Casting production
Alloy, component geometry, quantity, repeat demand and the agreed casting requirements.
03
Machining & finish
Functional surfaces, setups, finishing specification, cosmetic standards and masking.
04
Inspection & delivery
Acceptance criteria, reporting, sample or batch checks, packaging and delivery terms.
Supply both the as-cast model and finished-part drawing when available. Keep revisions and the machining scope aligned.
Review the full scopeMATERIAL & SURFACE SPECIFICATION
The alloy is
part of the design.
Specify a casting alloy and its applicable standard. Material selection, geometry and finish need to work together.
Discuss alloy & finishUse the exact casting specification.
Include alloy designation, material standard, condition and any required documentation. A CNC bar-stock grade is not automatically a casting grade.
Make the finish requirements visible.
Identify appearance zones, texture, coating requirements and protected interfaces. Discuss finish compatibility, including anodizing appearance on the requested casting alloy.
Tell us how the component will work.
Share temperature, corrosion exposure, sealing needs or other functional requirements that affect material, finish and acceptance.
FROM SAMPLE APPROVAL TO REPEAT ORDER
Control the handovers.
Check the finished result.
The drawing revision and acceptance plan stay connected through tooling, sampling, machining and delivery.

Clear scope.
Better decisions.
Why combine die casting with CNC machining?+
Die casting creates the component’s main geometry. Secondary machining can define selected functional faces, bores, threads and mounting features. The drawing review determines which features can remain as-cast and which require machining.
Is die casting suitable for my first small batch?+
Tooling adds an upfront investment, so the answer depends on geometry, quantity and repeat demand. WEKO can review a CNC-machined prototype or a small-batch machining route alongside a casting program. A machined prototype does not validate every property or risk of the final casting.
Which casting alloy should I specify?+
Use the exact casting alloy, applicable material standard and any condition or treatment requirements. A familiar CNC stock grade is not automatically a suitable casting specification. We review the requested alloy and part before confirming the route.
Which tolerances can you achieve?+
Specify limits separately for as-cast features and machined features, including datums and measurement requirements. Part size, alloy, tool layout and access affect feasibility. Final tolerances are confirmed for the quoted component; CNC equipment accuracy is not a blanket casting tolerance.
Can you machine castings we already have?+
Send the casting and finished-part drawings, material, available machining stock, quantity and any known condition issues. WEKO will review datum access, fixturing and the requested secondary operations before confirming suitability.
How are tooling ownership and costs handled?+
Ask the quotation to separate tooling, sampling, component production, machining and finishing. Agree tooling ownership, storage, maintenance, expected-life assumptions, engineering changes and transfer terms before release.
Do you include leak testing or internal-defect testing?+
Tell us the function and acceptance requirements in the RFQ. If leak, pressure or internal-defect checks are required, define the method, limits, sampling and documentation for a separate process review. They are not automatically included with every casting order.
Can die-cast parts be anodized or coated?+
Finish suitability and appearance depend on the casting alloy, surface condition and coating requirements. Send the finish specification, cosmetic zones and reference sample or color standard when applicable. We confirm the finish and acceptance criteria for your part.
What should I send for a quotation?+
Send a 3D model, dimensioned drawing and revision, casting alloy, first-order and repeat quantities, critical interfaces, finish, inspection needs and target schedule. If you have both as-cast and finished-part files, include both. Request an NDA before sharing sensitive drawings.
