Eathu takes you through the difference between sand-cast aluminum and cast aluminum

Sand casting aluminum and casting aluminum are two commonly used aluminum alloy casting processes. Although they can all produce high-quality aluminum alloy products, there are some differences between them. In this article, we will explore the differences between sand-cast aluminum and cast aluminum, as well as their respective advantages and disadvantages.

1. Process flow

Sand casting aluminum is a traditional casting process, which uses sand mold as a casting mold. First, the manufacturer needs to make a sand mold, and then pour the melted aluminum alloy into the sand mold. Once the aluminum alloy has solidified, the manufacturer can open the sand mold and remove the finished product.

Casting aluminum is another commonly used casting process, which uses metal molds as casting molds. First, the manufacturer needs to design and manufacture a metal mold, and then pour the melted aluminum alloy into it. Once the aluminum alloy has solidified, the manufacturer can open the metal mold and remove the finished product.

Step 2: Applicability

Sand cast aluminum is suitable for the production of large and complex parts, because the sand mold can be manufactured into any shape and size. In addition, the sand mold can be reused many times, making production costs lower.

Casting aluminum is suitable for the production of small and precision parts, as metal molds can provide higher precision and surface quality. In addition, metal molds can withstand higher pressures and temperatures, making them more suitable for the production of high-strength and high-temperature stress parts.

3. Cost

The production cost of sand-cast aluminum is relatively low because the sand mold can be reused many times and the manufacturing cost is low. In addition, the sand molding process does not require special equipment or skills.

The production cost of cast aluminum is relatively high because of the high cost of metal mold manufacturing. In addition, the metal mold manufacturing process requires special equipment and skills.

Step 4 Summarize

In general, sand casting aluminum and casting aluminum are important aluminum alloy casting processes. Which process to choose depends on the size, shape, accuracy and requirements of the part. If you need to produce large or complex parts, and the cost is low, you should choose sand-cast aluminum. If small or precision parts need to be produced, and high precision and surface quality are required, cast aluminum should be chosen.

No matter which process you choose, you need to pay attention to safety and environmental protection issues. In any type of aluminum alloy manufacturing process, relevant regulations and standards must be complied with to ensure that the production process is safe and reliable and has no negative impact on the environment.
