What is Aluminum Die Casting?
Casting is a process of metal smelting and processing, usually using the gravity of the metal in the mold for casting. But, aluminum die casting is not done by gravity, but by applying pressure. It’s kind of like injection molding. But it has a high technical content of core pulling, cooling and other systems. In general, the material is delivered through a central entrance into a cavity to be cast and “injected” to form parts.
Pros:
1. Good product quality, including:
- High size accuracy, generally equivalent to ISO CT6~CT7, or even up to CT4.
- Better surface finish than that of investment casting process.
- The strength and hardness are high. The strength is generally increased by 25~30% compared with sand casting, but the elongation is reduced by about 70%.
- Stable sizes, allowing for thin-walled complex castings.
2. High production efficiency: even if a small hot chamber die casting machine can die cast aluminum parts3,000~7,000 times in eight hours on average. The mold of aluminum die casting has a long life, which can reach hundreds of thousands of times, even millions of times.
3. Excellent economic effect: due to the precise size and good surface finish of aluminum die castings, generally no or little machining is required after casting. It not only improves the utilization rate of metal, but also reduces a lot of machining equipments and man-hours, that is why aluminum die casting is cheaper than aluminum sand casting process.
Cons:
Aluminum die casting is not suitable for small batch production, the main reason is that the manufacturing cost of die casting aluminum mold is high, so the small batch production is not economic. For aluminum castings with low volume, aluminum gravity casting process can be selected.
