The material used for die-casting—aluminum or its alloys—must be chosen based on the part’s intended use, required strength, and environmental factors. Different aluminum alloys (such as ADC12, A380, or A360) offer varying properties such as strength, corrosion resistance, and casting fluidity, and selecting the right alloy ensures optimal performance of the final product.

Process Planning:

The designer must plan the die-casting process, considering the best casting method (such as high-pressure die-casting or gravity die-casting) and how to manage aspects like material flow, mold cooling, and venting. Planning also includes evaluating the need for any post-casting operations, such as machining, polishing, or surface treatments.

2. Mold Design

Precision and Accuracy:

The design of the mold is a critical factor in achieving the desired quality and precision of the final part. Molds should be designed to accommodate complex shapes while ensuring that parts are produced with consistent dimensions and minimal defects. The mold design must provide adequate venting for gas escape, proper cooling channels to control the rate of cooling, and an efficient gating system that ensures uniform flow of molten metal.

Mold Materials and Durability:

Molds are typically made from high-strength steel or other durable alloys, as they need to withstand the high pressures and temperatures during the casting process. The mold’s ability to resist wear and tear is vital, as molds can become damaged or deformed after repeated use. High-quality, durable mold designs can help reduce production costs by extending the mold's lifespan and improving the consistency of each casting.
