Aluminum Alloy Die-Casting
We utilize a fleet of up to 40 die casting machines with tonnages ranging from 180 to 1,200 tons, enabling the production of both small and large batches of aluminum die castings. Our capabilities extend to the manufacture of extremely small and thin parts, with a minimum weight of 2 grams, and a minimum thickness of 1.2 millimeters.
Chi-Tai offers a variety of aluminum alloy die casting materials, which include:
- ASTM Standards: A356, A360, A380, A383
- These alloys adhere to the standards set by the American Society for Testing and Materials (ASTM), which are widely recognized across the United States and other countries.
- Each alloy features unique characteristics. For example, A356 is characterized by having excellent mechanical properties that are ideal for complex shapes; A380 ensures dimensional stability, making it suitable for precise applications; A383 provides high strength and dimensional stability, fulfilling demanding mechanical performance requirements.
- JIS Standards: ADC1, ADC3, ADC6, ADC10, ADC12
- These alloys comply with Japanese Industrial Standards (JIS), which are predominantly used in Japan and other Asian countries.
- Like ASTM alloys, each JIS alloy has distinct properties. For instance, ADC12 is recognized for its superior fluidity and casting performance, making it widely applicable in the manufacturing of automotive and electronics components.
Our expertise in die casting ensures precision and reliability across a wide range of industrial applications.
Advantages and Applications of Aluminum Die Casting
Aluminum die casting delivers several advantages:
- High Precision: producing intricately shaped and precisely dimensioned castings, making them ideal for demanding engineering applications.
- High Efficiency: rapid production speeds enable large-scale manufacturing with shorter lead times, helping to reduce costs.
- Lightweight: Aluminum alloys have a density of approximately 2.7 g/cm³, which is significantly lighter than zinc alloys, contributing to weight reduction, energy efficiency, and enhanced performance.
- Superior Mechanical Properties: Aluminum die castings offer strength, high-temperature resistance, and corrosion resistance, suitable for various industrial applications.
- Excellent Heat Dissipation: Thanks to their outstanding thermal conductivity, aluminum die castings are perfect for components requiring efficient heat dissipation, such as electronic heat sinks and LED lamp housings.
- Ease of Machining: Aluminum alloys are highly machinable, making them well-suited for manufacturing complex parts requiring subsequent machining and surface treatments.
- Environmental Sustainability: Aluminum is recyclable and can be reused indefinitely without degrading in quality, minimizing environmental impact and supporting sustainable development goals.
