Aluminum and Zinc Alloy Die Casting Services
Support for custom die cast metal parts, from drawing review and tooling planning to aluminum die casting, zinc die casting, CNC machining, surface finishing, inspection and export packing.
What Buyers Usually Call This Service
In the United States and Europe, aluminum alloy and zinc alloy metal part production is usually described as aluminum die casting, zinc die casting, custom die casting, pressure die casting or high pressure die casting. These terms are more natural than a direct translation such as alloy manufacturing.
We review 2D drawings, 3D files, material requirements, tolerance targets, surface finish, assembly fit and annual volume before recommending the practical manufacturing route.

Die Casting Parts We Can Support
Die casting is suitable for many metal housings, covers, brackets, connector shells and functional components that need stable shape, good strength and repeat production.

Aluminum Die Casting
For housings, brackets, covers, heat sink parts and structural components where weight, strength and machining accuracy matter.

Zinc Alloy Die Casting
For smaller precision parts, connector shells, latch parts, decorative components and hardware with detailed features.

CNC Machining and Finishing
Secondary machining, drilling, tapping, deburring, polishing, coating, plating and dimensional inspection before packing.
Typical Die Casting Project Workflow
A clear review process helps reduce risks around tooling, shrinkage, porosity, machining allowance, surface finish and assembly fit.

We check 2D drawings, 3D files, material, tolerance, appearance and annual quantity.

Wall thickness, draft, ribs, holes, bosses, machining allowance and parting line are reviewed.

Tool steel, cavity layout, gate, runner, cooling and ejection requirements are discussed.

Aluminum or zinc alloy is cast according to the confirmed tool and production plan.

Flash, gates and runners are removed before machining or surface treatment.

Critical holes, threads, flatness, sealing faces or bearing positions are machined as required.

Options may include polishing, sand blasting, powder coating, painting, plating or anodizing.

Dimensions, appearance, thread quality and packing protection are checked before shipment.
Common Aluminum and Zinc Alloy Materials
| Material | Typical Use | Review Point |
|---|---|---|
| ADC12 / A380 | Aluminum housings, covers, brackets and general die cast parts | Strength, machinability, surface finish and porosity control |
| A360 / A413 | Aluminum components requiring better corrosion or pressure-tight performance | Application, leakage risk, machining allowance and finishing |
| Zamak 3 | Zinc alloy hardware, connector shells and small precision components | Dimensional stability, plating and detailed features |
| Zamak 5 | Zinc alloy parts needing higher strength than common zinc die castings | Load, wear, assembly and surface treatment |
Important Points Before Quotation
- Part size, wall thickness and draft angle
- Material grade and mechanical requirement
- Machined holes, threads, sealing faces and flatness
- Surface finish such as powder coating, plating, painting or anodizing
- Porosity, leakage, cosmetic area and assembly risk
- Sample approval, inspection standard and export packing
Aluminum and Zinc Die Casting FAQ
What should I send for a die casting quotation?
Please send 3D files, 2D drawings, material grade, annual quantity, surface finish, tolerance requirements and any critical assembly information.
What is the difference between aluminum die casting and zinc die casting?
Aluminum die casting is often used for larger lightweight structural parts and housings. Zinc die casting is commonly used for smaller precision parts with detailed features and good surface finish.
Can die cast parts be CNC machined?
Yes. Critical holes, threads, sealing faces, flatness areas and assembly features are often machined after casting.
Can you support both plastic and metal parts for one project?
Yes. If your project includes plastic injection molded parts, molds, CNC machined parts or die cast metal components, we can review the drawings together and help organize the manufacturing route.
Send Die Casting Project Details
Please include drawings, material grade, tolerance, finish, estimated annual quantity and application details. We will review whether die casting, CNC machining or another process is more suitable.

Need aluminum or zinc die cast parts?
Send your drawings and requirements. We will review tooling, material, machining, finishing and inspection points before quotation.
