Custom Aluminum & Zinc Die Casting Services
High-precision die cast components with integrated CNC machining, finishing, assembly, and global DDP delivery. Built for scalability and tooling ROI.
Why Procurement Leaders Choose Die Casting
We don't just pour metal. We optimize your supply chain by converting expensive multi-part assemblies and heavily machined components into single, cost-effective die castings.
Lower Unit Cost
The ultimate solution for medium and high-volume production. Once the tool is paid off, the piece price drops dramatically compared to CNC machining.
Complex Geometries
Consolidate multiple parts into one. Cast thin walls, complex internal features, and near-net shapes that reduce costly assembly and secondary machining operations.
Fast Production
High-speed injection allows thousands of parts to be produced consistently and rapidly, ensuring your supply chain never faces stockouts.
Excellent Surface Finish
Ideal for cosmetic and visible components. Parts come out of the mold with smooth finishes, ready for powder coating, plating, or painting.
Strong Mechanical Properties
Aluminum and zinc alloys offer high strength-to-weight ratios, dimensional stability, and excellent EMI/RFI shielding for electronic housings.
Integrated Manufacturing
We don't just cast. We provide Casting + Precision CNC Machining + Surface Finishing + Assembly, delivering a ready-to-use component.
When Does Die Casting Become Cost Effective?

Max Savings
Pro Tip for Sourcing: While die casting tooling requires an upfront investment, the dramatic reduction in per-part cycle time means the tooling cost is typically amortized quickly. For volumes over 1,000 parts annually, die casting often delivers a 30% to 60% cost reduction compared to machining from solid billet.
Most Popular Die Casting Alloys
Selecting the right alloy balances material cost, structural integrity, and secondary finishing capabilities.
Aluminum Alloys
Lightweight, high dimensional stability, excellent for high operating temperatures.
| Alloy | Best For | Machinability |
|---|---|---|
| ADC12 | General purpose, excellent castability, automotive parts. | Good |
| A380 | Most common US standard. Great balance of properties. | Good |
| A360 | High corrosion resistance, pressure tightness. | Fair |
| AlSi9Cu3 | European standard, high strength, engine components. | Good |
Zinc Alloys
Superior strength, excellent formability, ideal for very tight tolerances and plating.
| Alloy | Best For | Plating |
|---|---|---|
| Zamak 3 | Industry standard for zinc. Excellent balance of physical properties. | Excellent |
| Zamak 5 | Higher strength and hardness than Zamak 3. Used in automotive. | Excellent |
| ZA-8 | High performance, excellent creep resistance, can be hot-chamber cast. | Good |

Proven Across Demanding Industries
From heat dissipation in EV chargers to rugged enclosures for industrial automation.
Die Casting + CNC Machining
Experienced buyers know that die cast parts rarely come out of the mold 100% ready for assembly. Tight tolerances, threads, and perfectly flat mating surfaces require secondary operations. We manage the entire process in-house.
Surface Finishes & Coatings
Can Die Cast Parts Be Anodized?
Not all die casting alloys are suitable for cosmetic anodizing. Common alloys like ADC12 and A380 contain high silicon levels, which turn dark gray or black when anodized. If a clear or brightly colored anodized finish is required, we must carefully select specific low-silicon alloys or recommend alternative finishes like powder coating or painting. We help you avoid this common engineering pitfall.

Die Casting Tooling & Molds
Everything you need to know about the upfront investment and long-term asset management.
Tooling Cost
Costs range from $3,000 for simple single-cavity zinc molds to $50,000+ for complex multi-cavity aluminum molds. We offer competitive tooling pricing by manufacturing molds in-house.
Tool Lead Time
Typical lead time for tool design, manufacturing, and T1 samples is 3 to 6 weeks, depending on part complexity and mold size.
Tool Life
Aluminum molds typically last 50,000 to 100,000 shots. Zinc molds can last 500,000 to 1,000,000+ shots due to lower melting temperatures.
Engineering Changes
"Metal safe" changes (removing tool steel to add part volume) are relatively inexpensive. Adding tool steel requires welding or inserts and is more costly.
Tool Ownership
You own the mold. Once the tooling invoice is fully paid, the custom mold is your exclusive property, though it remains at our facility for production.
Tool Maintenance
We provide lifetime routine maintenance for your mold as long as it stays in our facility for production, ensuring consistent part quality over time.
From Drawing to Global Delivery
Automotive-Grade Quality Control
We adhere to strict ISO 9001 standards, providing comprehensive documentation for OEM manufacturers.
- CMM Inspection for tight tolerances
- First Article Inspection (FAI) Reports
- Material Certification & Spectrometer Testing
- PPAP Level 1-3 Support
- Process Traceability & Control Plans
