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.

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

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.

Frequently Asked Questions

Clear answers for sourcing professionals.

What is the minimum order quantity (MOQ)?
While we do not have a strict MOQ, die casting is most economical for runs of 1,000+ parts due to the tooling setup costs. For lower volumes, we may recommend our CNC machining services.
Can you machine die cast parts?
Yes, absolutely. Most die cast parts require secondary CNC machining for tight tolerances, threads, or perfectly flat mating surfaces. We have a massive in-house CNC facility to handle this seamlessly.
Who owns the mold? Can molds be transferred?
You own the mold 100% once the tooling invoice is paid. While molds are designed to fit specific machines, they can technically be transferred. However, keeping the mold with us ensures we provide free lifetime maintenance for production runs.
Can you stock inventory in the USA?
Yes! We have a USA Warehouse support system. For high-volume contracts, we can produce in bulk, ship by sea to our US facility, and release inventory to you just-in-time, improving your cash flow and lead times.
Can you ship DDP?
Yes, we offer DDP (Delivered Duty Paid) global shipping. We handle all customs, duties, and logistics, delivering the parts directly to your dock with no hidden fees or paperwork hassles.
