Aluminum Die Casters for OEMs — HPDC, CNC & Fast RFQ

If you’re an OEM buyer looking for aluminum die casters you can actually count on, we get where you’re coming from. You don’t just need a supplier — you need a partner who can handle mold development, deliver consistent part quality, and stay on schedule. That’s been our focus for over 20 years.

What Do Aluminum Die Casters Really Offer OEM Buyers?

When people think of die casting, they usually picture molten metal going into a mold. But for OEM projects, it’s far more than that. We provide an end-to-end production service that ensures your design gets translated into a stable, repeatable part.

Here’s what we offer:

  • Mold design and engineering support (DFM-ready)
  • High-pressure die casting (180T to 2000T machines)
  • Precision CNC machining (±0.01 mm accuracy)
  • Surface finishing: sandblasting, powder coating, anodizing, and more
  • Dimensional and material reports (CMM, X-ray, spectrometer)
  • Packaging and labeling tailored to your warehouse standards

We’ve worked with everything from simple brackets to complex medical housings, and each customer receives the same detailed workflow and documentation.

Which Alloys Do We Cast Most Often?

Most buyers already have preferred alloys or local equivalents. Here’s what we use regularly and why:

AlloyComposition SummaryWhy It’s Common
ADC12Aluminum-Silicon-CopperBest for flowability, tight tolerance, and general structural parts.
A380Aluminum-Silicon-CopperNorth American standard; great balance of strength and weight.
ZL101Aluminum with High SiliconHigh heat dissipation; often used in electronics and lighting parts.
Custom AlloysPer drawing specsWe match to customer requirements for mechanical properties or coatings.

If you’re not sure what to pick, we usually start with ADC12 unless your part requires special strength or conductivity properties.

How Fast Can We Quote and Deliver Aluminum Castings?

Speed matters — especially when you’re managing multiple suppliers or facing a tight product launch window.

  • 3 working days: Full quote with mold cost, unit price, and delivery terms
  • 15 to 30 days: New mold completion (depends on part complexity)
  • Weekly capacity: 100,000–200,000 parts
  • Shipping: EXW, FOB, or CIF — we’ve shipped to over 30 countries

We also support small-batch prototyping (50–200 units) before going full-scale.

How We Ensure Dimensional Accuracy and Part Repeatability

We currently operate high-pressure die casting machines ranging from 180T to 2000T, depending on your part size and clamping force requirements.

  • 180T–280T: Small brackets, sensor housings, USB connectors
  • 400T–800T: Lighting parts, motor enclosures, pump covers
  • 1000T–2000T: Structural parts, heat sinks, inverter boxes

To guarantee repeatability:

  • Mold temperatures are stabilized using mold temperature controllers
  • Spray systems and injection parameters are fully automated
  • All CNC-finished parts are checked with 3D coordinate measuring machines (CMM)
  • We routinely inspect ±0.05 mm tolerances, and for critical features, we go up to ±0.01 mm

Quality isn’t just about precision — it’s also about consistency batch after batch.

What Kind of Parts Do We Die Cast for OEMs?

Here are some real examples of aluminum die cast parts we produce for clients across various industries:

ProductIndustryHighlights
Motor HousingsAutomotive, EVMachined post-casting; includes sealing grooves
EnclosuresMedical, IndustrialMulti-cavity parts with threaded holes
Heat SinksEnergy, LEDLong fin profiles with thermal coatings
Covers & CapsGeneral OEMSimple shapes, low tooling costs
Custom PartsAny IndustryMade to drawing — with full technical review

Every new part starts with a drawing or 3D file. We’ll review it, quote tooling, and walk you through the next steps.

Why OEM Buyers Choose Our Aluminum Die Casting Factory

We’re not a broker or trading company. Everything — from mold building to casting to CNC finishing — is done in-house or under our direct supervision.

Here’s why customers stay with us:

  • 20+ years of exporting experience, especially to the EU, US, and Japan
  • Clear RFQ process with fast communication (WhatsApp or email)
  • One project manager per order, who understands engineering + logistics
  • Mold maintenance and support for repeat orders at minimal cost
  • Flexible MOQs: From 500 pcs to 50,000 pcs depending on part type

We also offer packaging options that meet Amazon FBA, industrial crate, and custom box requirements.

FAQs About Aluminum Die Casters
