Aluminum Die Casting Manufacturer | High-Precision OEM Parts by EATHU
The Power of Aluminum Die Casting
Aluminum die casting is a highly efficient and reliable manufacturing process that enables the production of complex and dimensionally stable components with excellent mechanical properties. For industries such as automotive, aerospace, electronics, and industrial machinery, die-cast aluminum parts are an essential component of modern engineering.
At EATHU, we specialize in OEM aluminum die casting solutions tailored to meet the unique needs of our global clients. With advanced manufacturing capabilities, a skilled technical team, and strict quality control, we deliver high-precision parts with competitive pricing and fast turnaround times.
What is Aluminum Die Casting?
Aluminum die casting is a non-ferrous metal casting process that involves injecting molten aluminum under high pressure into reusable steel molds, known as dies. This process is ideal for producing high-volume, net-shape components with fine surface finishes and tight dimensional tolerances.
Unlike traditional casting methods such as sand casting or gravity casting, aluminum die casting provides:
Superior surface quality
Minimal post-processing
Repeatable accuracy
Enhanced material strength
The result Reliable parts with consistent quality at lower production costs—perfect for mass production.
How the Aluminum Die Casting Process Works at EATHU
At EATHU, we manage every step of the aluminum die casting process with precision and professionalism:
Mold Design & Prototyping
Our engineers collaborate with clients to design optimal mold geometry based on part specifications. Using CAD/CAM and simulation software, we ensure minimal material waste, perfect fill flow, and long tool life.
Melting & Injection
High-quality aluminum alloy ingots are melted in advanced electric furnaces. The molten metal is then injected into the die at pressures up to 1500 bar, ensuring uniform density and detailed features.
Cooling & Ejection
Once the part cools and solidifies inside the mold, it is ejected by automatic ejector pins. The cycle time is short—ranging from a few seconds to under a minute—making it ideal for high-volume production.
Post-Casting Finishing
We offer a full range of post-casting services, including:
Deburring & Surface Cleaning
CNC Machining
Anodizing, Powder Coating, Electroplating
Assembly and Packaging
Each part undergoes rigorous inspection before delivery.
Materials We Use: High-Performance Aluminum Alloys
EATHU primarily works with industry-standard aluminum alloys including:
| Alloy | Key Features | Typical Applications |
|---|---|---|
| A380 | Excellent castability, corrosion resistance, pressure tightness | Automotive, communication housings |
| ADC12 | Good strength, dimensional stability, cost-effective | Motor housings, general hardware |
| A360 | High corrosion resistance, good fluidity | Marine, electronics components |
We help clients select the most suitable alloy for their specific use case, balancing mechanical performance, surface quality, and cost-efficiency.

Why Aluminum? Key Advantages of Die Cast Aluminum Parts
Aluminum is one of the most widely used metals in die casting due to its unique combination of physical and chemical properties:
Lightweight yet Strong – Ideal for reducing part weight without compromising durability.
Excellent Corrosion Resistance – Suitable for outdoor and harsh environments.
Thermal Conductivity – Helps with heat dissipation in electronic components.
Dimensional Stability – Maintains shape and tolerance over time.
Eco-Friendly – Fully recyclable, contributing to sustainable production.
Compared to steel, zinc, or plastic, aluminum offers a better strength-to-weight ratio and more refined appearance—especially important in automotive and consumer applications.
