The automotive industry today is the world's largest buyer of aluminum sand casting services, but it's not the only sector of interest. At the same time, more than half of the cars on the road have at least one part made with a mold. This material and process has been used to make safe, efficient, lightweight vehicles since the early 1900s, from aluminum transmission housings and pistons to rims and radio components.

If you're looking for an inexpensive and versatile method of aluminum forming, casting may be the key. This is a relatively simple process and is often used to process automotive and aerospace products, but can be found elsewhere as well. Most large aluminum fabrication projects use sand molds to cast aluminum safely and efficiently. Therefore, aluminum sand casting has grown rapidly in popularity and practicality.

What are the advantages of sand casting process?
Any legitimate mechanic will tell you that sand casting has several advantages, especially when you compare the process to more complicated and expensive alternatives. This is because aluminum parts cast in sand molds behave similarly to gray cast iron parts. In fact, here are the top 5 reasons why sand casting is often the best choice for large metal fabrication projects:
1. machinability of materials
Highly machinable materials such as aluminum offer greater flexibility in the design process. Machinists can easily cast intricate core components and parts with complex feet, while still adhering to strict industry standards and innovative practices.
2. Low mold cost
The aluminum sand casting process has one of the lowest tooling costs of all machining methods because it uses one-shot tooling. As a result, ASC also shortens lead times, giving project managers more leeway for prototyping and redesign.
3. High-quality, high-speed rendering
Whether you're making parts for small projects or mass production is a major industry, the fast production speed of cast aluminum is very beneficial. In fact, the efficient way each part is manufactured allows manufacturers to produce thousands of parts per day.
4. wide availability
There are many different aluminum grades and alloys to choose from, making it easier for you to customize your metal products and machining results. You can also use a variety of properties, with tensile strengths ranging from 16k to 50k, which provide excellent corrosion resistance.
5. excellent surface finish
When machined correctly, high-density aluminum molds provide an excellent surface finish that can be used in countless applications. This is because the increased pressure and advanced machining techniques create castings with great looks and solid interiors. This process and material also provides the least sensitive gate, feed and heat sink structures available in modern mass production. Mechanics can use it with almost any ferrous or non-ferrous alloy known to man, and it's still not as expensive as other crafts.
