Solutions
Die Casting + CNC Post-Machining
FSD Precision supports aluminum and zinc die cast parts that need trimming, CNC post-machining, deburring, surface finishing, dimensional inspection, and delivery coordination.
Project Stage
What This Solution Supports
This solution focuses on a project stage or coordination problem, not an industry category or a single manufacturing service.
Challenges
Common Project Challenges
02
Holes, threads, sealing faces, datums, and assembly areas often need CNC post-machining.
03
Trimming and deburring must be coordinated before finishing.
04
Surface finishing must match corrosion, appearance, conductivity, or functional needs.
05
Dimensional control is needed after casting and machining.
Project Flow
Project Flow
The flow keeps drawing review, engineering review, sample validation, tooling or production planning, manufacturing, finishing, inspection, and delivery connected.
Step 01
Drawing Review
Review casting geometry, machined features, tolerances, finish requirements, and application needs.
Step 02
Die Casting Planning
Plan material, mold requirements, parting line, gates, ejector areas, and machining allowance.
Step 03
Casting, Trimming, and Deburring
Coordinate casting production, trim removal, deburring, and cleaning before machining.
Step 04
CNC Post-Machining
Machine critical holes, threads, sealing surfaces, datums, and assembly features.
Step 05
Surface Finishing
Coordinate powder coating, painting, plating, sandblasting, polishing, or other suitable finish routes.
Step 06
Inspection and Delivery
Inspect cast and machined dimensions, surface finish, packaging, and shipment readiness.
Engineering Review
Engineering Review Before Manufacturing
Before quotation or production, FSD reviews the part structure, tolerance requirements, material selection, surface finish, assembly fit, and possible manufacturing risks.
Machining allowance and critical feature review before die casting.
CNC post-machining coordination for assembly-critical surfaces.
Surface finish route selection for cast aluminum and zinc parts.
Dimensional inspection and reports upon request.
Packaging and delivery coordination for finished die cast parts.

FAQ
Die Casting + CNC Post-Machining FAQ
Common questions buyers ask before sending drawings, confirming samples, or moving into production.
Why do die cast parts need CNC post-machining?
Die casting is efficient for repeat shapes, but holes, threads, sealing faces, datums, and tight-tolerance assembly features often need CNC machining.
Which die cast features are usually machined?
Common features include threaded holes, precision bores, flat sealing faces, bearing seats, mounting datums, and connector interfaces.
Can FSD coordinate casting, machining, and finishing together?
Yes. FSD can coordinate die casting, trimming, CNC post-machining, deburring, finishing, inspection, and delivery.
What materials are used for this solution?
The main materials are aluminum and zinc alloy, depending on part size, detail, strength, weight, and finish requirements.
