In the world of custom metal parts manufacturing, casting provides an efficient way to form complex geometries — but precision often starts after the pour. To achieve tight tolerances, consistent performance, and high-end finishes, CNC machining is the key that unlocks the full potential of cast components.

At Yuhuan Mindao, we integrate precision CNC milling and turning into our workflow to bridge the gap between rough casting and final specification, offering customers components that not only fit but also perform flawlessly.

Why Machining Matters After Casting

Casting techniques — whether sand, investment, or die casting— are excellent for near-net shapes. However, they inherently come with dimensional variation, surface irregularities, and internal stress points.

CNC machining ensures:

Dimensional Accuracy: Critical dimensions are brought within ±0.01 mm tolerances, eliminating fitment issues in complex assemblies.

Surface Quality: Machining smooths rough surfaces and prepares parts for coating, sealing, or direct use in demanding applications.

Repeatability: Every part is machined identically, ensuring consistency from batch to batch.

Key CNC Processes We Apply

CNC Milling

Ideal for precision surfaces, slots, and hole patterns. We use multi-axis mills to handle complex geometries without repositioning.

CNC Turning

Essential for round or cylindrical parts, such as shafts, flanges, and valve components — especially where concentricity is critical.

Post-Machining Inspection

All parts undergo CMM inspection or digital measurement to confirm accuracy before shipment.

Real Benefits for Cast Component Applications

Whether your components are used in pumps, valves, automotive assemblies, or medical equipment, the combination of casting and CNC machining offers:

Lower Cost per Part (compared to full billet machining)

High Material Utilization

Design Flexibility with Guaranteed Precision

We often support projects where castings alone do not meet performance requirements — and our CNC capabilities allow us to add the necessary precision where it matters most.
